1. What is the difference between scavengers and decomposers?  

Explanation

Scavengers and decomposers have different roles in the process of breaking down organic matter. Scavengers, such as vultures and hyenas, consume the organic debris, especially animal remains, as a source of food. On the other hand, decomposers, which are bacteria and fungi, play a crucial role in breaking down the remaining organic matter into simpler substances, thus completing the final step in the food web. Therefore, scavengers primarily consume the organic debris, while decomposers break it down into simpler substances.

Explanation

Strong winds can cause the fine sand particles on an ocean beach to bounce and mound into piles. This process is known as saltation. Transpiration refers to the process by which plants release water vapor into the atmosphere. Ocean waves are the result of the wind's interaction with the surface of the ocean. Mineralization refers to the process of converting organic matter into minerals.

Submit
3. Identify the event shown in the image.

Explanation

The event shown in the image is the "Birth of an inlet." This term refers to the formation of a new waterway or channel that connects a body of water, such as a river or ocean, to a previously landlocked area. It typically occurs due to natural processes such as erosion, sedimentation, or changes in water flow. In the image, we can see the creation of a new inlet where the land is being eroded and water is flowing into the previously dry area.

Submit
4. Identify each of the seven barrier island coastal habitats in order from 1-7:

Explanation

The correct answer is Ocean, Ocean Beach, Sand Dune, Maritime Forest, Salt Marsh, Sound, Tidal Flat. This order represents the typical progression of barrier island coastal habitats from the open ocean towards the mainland. The ocean is the first habitat, followed by the ocean beach, which is the area of the beach directly impacted by waves and tides. Next is the sand dune, which forms behind the beach and provides protection from storms. The maritime forest is a wooded area that develops behind the dunes. The salt marsh is a wetland habitat that forms in the low-lying areas behind the forest. The sound refers to the body of water between the island and the mainland. Finally, the tidal flat is an area of mud or sandy sediment that is exposed during low tide.

Submit
5. Nitrogen is scarce on the dunes because:

Explanation

The reason why nitrogen is scarce on the dunes is because there is little or no decaying plant and animal material to enrich the dunes. Nitrogen is an essential nutrient for plant growth, and it is typically obtained from the decomposition of organic matter. In the absence of decaying material, there is a lack of nitrogen available for plants to take up and use for their growth and development.

Submit
6. Why are dunes made of finer sand than the beaches?

Explanation

Saltation is the process by which sand grains are transported by wind in a bouncing or hopping motion. This process tends to carry only the finest sand grains, as larger grains are too heavy to be lifted and transported effectively. Therefore, dunes, which are formed by the accumulation of wind-blown sand, are made up of finer sand particles compared to the beaches where larger grains can be found.

Submit
7. What is the original source of energy for the entire seashore community?  

Explanation

The sun is the original source of energy for the entire seashore community. It provides sunlight which is essential for photosynthesis in plants and algae, the primary producers in the community. These producers convert solar energy into chemical energy through photosynthesis, which is then passed on to the rest of the community through the food chain. Therefore, the sun is the ultimate source of energy for all organisms in the seashore community.

Submit
8. Identify this hard stabilization image and what occurs as a result of its presence:

Explanation

A seawall is a hard stabilization structure that is built parallel to the coastline to protect land from erosion by redirecting wave energy. However, the presence of a seawall can also lead to increased erosion of both the front and sides of the wall. This occurs because the redirected wave energy causes increased turbulence and scouring, which can undermine the stability of the wall and lead to erosion.

Submit
9. IDENTIFY: the barrier island formation step in this diagram:

Explanation

Step 4 explains that the barrier spits, which were formed in Step 3, become separated from the mainland due to a combination of sea level rise and storms. These factors breach the barrier spits, cutting them off from their original source of sand. As sea levels continue to rise, the low coastal plain on the mainland becomes flooded, causing the mainland shore to retreat. This further separates and isolates the barrier island from the mainland.

Submit
10. Match the location where the subtidal zone is found.

Explanation

The subtidal zone is always covered by water, below the low tide water line. This means that even at low tide, the subtidal zone remains submerged. It is located below the low tide water line, which is the point where the water recedes to during low tide. This distinguishes the subtidal zone from the intertidal zone, which is the area between the high and low tide lines and is exposed to air during low tide. The subtidal zone is characterized by a constant presence of water, making it an important habitat for marine organisms.

Submit
11. Match the location where the supratidal zone is found.

Explanation

The supratidal zone is the area above the high tide line. This means that it is located above the point where the highest tide reaches during a tidal cycle. It is the highest part of the intertidal zone and is only exposed to air during low tide. The supratidal zone is characterized by its dry conditions and is often influenced by wind and wave action. It is home to organisms that are adapted to survive in this harsh environment, such as specialized plants and insects.

Submit
12. What does this arrow identify?

Explanation

This arrow identifies a longshore current. A longshore current is a current that flows parallel to the shoreline, caused by the oblique angle at which waves approach the beach. It moves sediment along the coast, resulting in the formation of sandbars and beaches. The arrow in the question indicates the direction in which the longshore current is flowing.

Submit
13. What does this diagram show?

Explanation

This diagram shows the process of barrier island migration. Barrier islands are dynamic landforms that constantly shift and move over time due to various natural processes such as waves, tides, and currents. This diagram likely illustrates the movement of a barrier island as it migrates or moves in response to these forces.

Submit
14. Identify a key adaptation of the mole crab and coquina clam for living in the in the ocean beach intertidal zone:

Explanation

Both the mole crab and coquina clam have adapted to living in the ocean beach intertidal zone by burrowing rapidly into the sand. The coquina clam burrows as a wave recedes, while the mole crab burrows backward each time a wave advances. This adaptation allows them to avoid being washed away by the waves and provides them with protection from predators. By burrowing into the sand, they can also maintain a stable environment and access food sources that are found within the sand.

Submit
15. Match the location where the intertidal zone is found.

Explanation

The intertidal zone is the area that is exposed to air at low tide and covered by water at high tide. It is the region between the high and low tide lines, where organisms are adapted to survive in both aquatic and terrestrial conditions. This zone experiences regular fluctuations in temperature, salinity, and moisture levels, creating a challenging environment for organisms to inhabit.

Submit
16. Choose the best definition of a barrier island.

Explanation

A barrier island is a long, narrow body of sand that is separated from the mainland by a sound and from other islands by inlets at both ends. This definition accurately describes the characteristics of a barrier island, including its shape, composition, and geographical location. The mention of a sound and inlets emphasizes the isolation of the island from the mainland and other islands, further highlighting its unique features.

Submit
17. Identify this structure:

Explanation

A seawall is a structure built along the shoreline to protect land from erosion caused by waves and tides. It is typically made of concrete or stone and is designed to withstand the force of the water. Seawalls are usually built parallel to the coastline and act as a barrier, preventing the waves from reaching the land. They are commonly found in areas where there is a high risk of coastal erosion and are used to protect coastal communities, infrastructure, and beaches.

Submit
18. Spartina alterniflora (marsh cordgrass) is the most abundant and ecologically most important large plant of the marsh. What makes it so important?

Explanation

Spartina alterniflora, also known as marsh cordgrass, is considered the most abundant and ecologically important large plant of the marsh due to its salt tolerance. This means that it can thrive in environments with high salt content, such as coastal areas or marshes. This ability allows it to outcompete other plant species and establish itself as a dominant species in these habitats. Its salt tolerance also enables it to provide important ecosystem services, such as stabilizing and protecting coastal areas from erosion.

Submit
19. What is the effect of salt spray on back dune trees and shrubs?

Explanation

Salt spray from wind kills back the tips of the tree and shrub branches causing them to look sheared and grow stunted and twisted. This is because salt spray contains high levels of salt, which is detrimental to the growth and health of plants. The salt damages the tissues of the branches, leading to their death and causing the plants to appear sheared and distorted. Additionally, the salt can also hinder the absorption of water and nutrients by the plants, further stunting their growth.

Submit
20. Identify the sand movement in the diagram in the order of these numbers: #1 _______________, #2 ______________, #3 ______________

Explanation

The correct answer is #1 suspension, #2 saltation, #3 creep. In the diagram, sand particles are initially lifted into the air and suspended in the wind, which is known as suspension. Then, these suspended particles start to fall back to the ground due to gravity, but some of them gain enough momentum to be lifted back into the air again, creating a bouncing or hopping motion, known as saltation. Finally, the sand particles that do not get lifted into the air settle on the ground and move slowly along the surface through a process called creep.

23. How deep/thick are Barrier Islands?

Explanation

Barrier islands are typically formed by the accumulation of sand and sediment over time. They are long, narrow strips of land that run parallel to the mainland coast. The depth or thickness of barrier islands can vary, but on average, they are known to be around 30 to 60 feet deep. This depth is a result of the deposition of sand and sediment by waves and currents, as well as the natural processes of erosion and accretion. The specific depth can also be influenced by factors such as tides, storms, and the overall geology of the area.

Submit
24. What is littoral drift?

Explanation

Littoral drift refers to the movement of sand along the shoreline caused by the long shore current. This current runs parallel to the shore and carries sand and sediment in a zigzag pattern. As the waves approach the shore at an angle, they create a current that moves sediment along the coast. This process is responsible for shaping and reshaping beaches and coastal landforms over time.

Submit
25. What kind of sediment settle in the sound?

Explanation

Fine silt is the type of sediment that settles in the sound. Silt particles are smaller than sand particles but larger than clay particles. They have a smooth texture and can be easily transported by water. In a sound, where water movement is relatively calm, fine silt particles have the opportunity to settle and accumulate over time. This sediment type is commonly found in estuaries and coastal areas where rivers meet the ocean.

Submit
26. What kind of sediments settle on the ocean beach?

Explanation

Coarse sand is the correct answer because it is the type of sediment that commonly settles on the ocean beach. Coarse sand particles are larger in size compared to silt and clay, and they are often found in abundance on beaches due to the action of waves and currents. Gravel, although also found on some beaches, is less common than coarse sand.

Submit
27. Most supratidal animals are ____________ that feed on debris and detritus along the strand line.

Explanation

Supratidal animals are those that live above the high tide line, where they have access to debris and detritus. Scavengers are organisms that feed on dead or decaying organic matter, making them well-suited to this environment. They play an important role in breaking down and recycling organic material, helping to maintain the ecosystem's balance. Decomposers, producers, and herbivores are not specifically mentioned in the context of supratidal animals and their feeding habits.

Submit
28. What causes red tide?

Explanation

Dinoflagellates cause 'red tides' when sudden blooms of certain species occur. These organisms have tiny whiplike tails that enable them to move and swirl about in the water. When there is an excessive growth of dinoflagellates, it leads to a red tide phenomenon. The sudden increase in their population can be triggered by various factors such as nutrient availability, temperature, and light conditions. The red coloration is caused by the pigments present in the dinoflagellates, which can give the water a reddish or brownish appearance.

Submit
29. IDENTIFY: The two major currents that affect North Carolina's climate.

Explanation

The correct answer is Laborador/Virginia and the Gulf Stream currents. These two major currents have a significant impact on North Carolina's climate. The Laborador/Virginia current is a cold current that flows southward along the coast, bringing cooler temperatures to the region. On the other hand, the Gulf Stream current is a warm current that flows northward offshore, bringing warmer temperatures to the area. The interaction between these two currents influences the temperature and weather patterns in North Carolina.

Submit
30. What causes shoreline habitats to have extremes in water temperature?

Explanation

Shoreline habitats experience extremes in water temperature due to the influence of currents and tides. Currents refer to the movement of water in a particular direction, which can bring warmer or colder water to the shoreline habitats. Tides, on the other hand, are the rise and fall of sea levels caused by the gravitational pull of the moon and the sun. The changing tides can also affect water temperature by bringing in warmer or colder water. Therefore, the combination of currents and tides is responsible for the extremes in water temperature observed in shoreline habitats.

Submit
31. Why are estuaries considered brackish?

Explanation

Estuaries are considered brackish because they are a mixture of fresh and saltwater. This occurs when rivers or streams flow into the ocean, creating a transition zone where the freshwater mixes with the saltwater. The varying levels of salinity in estuaries create a unique environment that supports a diverse range of plant and animal species adapted to these conditions.

Submit
32. What are the three basic components of a food web?

Explanation

The correct answer is "Three basic components of a food web are producers, consumers and decomposers." This answer accurately identifies the three main groups of organisms that play a crucial role in a food web. Producers, such as plants and algae, convert energy from the sun into food through photosynthesis. Consumers, including herbivores, carnivores, and omnivores, obtain energy by consuming other organisms. Decomposers, such as bacteria and fungi, break down dead organisms and organic matter, returning nutrients back into the ecosystem. These three components are interconnected and form the foundation of energy flow and nutrient cycling in a food web.

Submit
33. Identify which beach season is shown in the diagram below:

Explanation

The diagram shows leaves falling from the trees, indicating that it is autumn or fall. The other options, winter, spring, and summer, do not match the visual cues in the diagram.

Submit
34. How is energy passed through the community? 

Explanation

Energy is passed through the community through feeding relationships. This means that energy flows from one organism to another as they consume and are consumed by other organisms in the community. Producers, such as plants, convert sunlight into energy through photosynthesis. Herbivores then consume these plants, transferring the energy to themselves. Carnivores, in turn, consume the herbivores, continuing the transfer of energy. This process continues throughout the community, creating a food chain or web, and ensuring that energy is passed along to different organisms.

Submit
35. Ocean beach habitats have three distinct zones:

Explanation

The correct answer is the subtidal zone of crashing breakers with swirling sand and shallow water; the intertidal zone, alternately covered and exposed by tidal waters; and the dry, sandy supratidal zone extending to the base of the sand dunes. This answer accurately describes the three distinct zones found in ocean beach habitats. The subtidal zone refers to the area below the low tide mark where the waves crash and the water is shallow. The intertidal zone is the area between the high and low tide marks that is alternately covered and exposed by tidal waters. The supratidal zone is the area above the high tide mark and extends to the base of the sand dunes.

Submit
36. Phytoplankton are_______________________

Explanation

Phytoplankton are free floating microscopic plants that are the basis of the marine food chain. They are responsible for producing most of the oxygen in the atmosphere through photosynthesis and serve as a primary food source for many marine organisms. They play a crucial role in maintaining the balance of marine ecosystems and are essential for the survival of other organisms in the food chain.

Submit
37. Why do marshes have that characteristically rotten egg odor?

Explanation

The marshes have a characteristically rotten egg odor because decomposition in the marshes uses up a lot of oxygen and releases hydrogen sulfide. The reduced oxygen level in combination with the release of hydrogen sulfide creates the unpleasant smell.

Submit
38. What is surface creep?

Explanation

Surface creep refers to the phenomenon where saltating grains of sand, which are grains that are bouncing or hopping along the surface due to wind or water movement, collide with heavier grains that are larger than one millimeter in diameter. This collision causes the heavier grains to experience a slight forward movement along the surface.

Submit
39. Identify the sides of a dune.  #1 ____________  and  #2 _____________

Explanation

The sides of a dune are commonly referred to as the leeward side and the windward side. The leeward side is the side of the dune that is sheltered from the wind and is typically less steep. The windward side, on the other hand, is the side that faces the oncoming wind and is usually steeper and more exposed to erosion.

Submit
40. Why are the Outer Banks so far from the mainland coast of North Carolina?

Explanation

As sea levels rise, the mainland coastal plain is receding at a faster rate than the islands are migrating landward. This means that the islands are being left behind and are becoming further from the mainland coast of North Carolina.

A gastropod is a type of mollusk that has one shell. It is specifically referred to as a marine snail.

Submit
53. Why do North Carolina eastern oysters cluster in oyster beds? 

Explanation

The reason North Carolina eastern oysters cluster in oyster beds is because competition is fierce among organisms that need to attach to solid substrate. However, North Carolina lacks rocky solid substrate for these organisms to live attached to. Therefore, the oysters cluster together as a survival strategy, as they are unable to easily attach to cordgrass or other solid surfaces in the sound or marsh.

Submit
54. The kind of sediment deposited in shoreline habitats depends on:

Explanation

Water turbulence refers to the movement and agitation of water caused by various factors such as waves, currents, and wind. In shoreline habitats, water turbulence plays a significant role in determining the type of sediment that gets deposited. High levels of turbulence result in the deposition of coarser sediments such as sand and gravel, while low levels of turbulence lead to the deposition of finer sediments like silt and clay. Therefore, the kind of sediment deposited in shoreline habitats is directly influenced by the level of water turbulence present in the area.

Submit
55. The deep root system of American Beach grass and Sea Oats help these plants avoid _________________ & _________________.  

Explanation

The deep root system of American Beach grass and Sea Oats help these plants avoid dehydration and evaporation. The deep roots allow the plants to access water from deeper soil layers, reducing the risk of dehydration.

It covers the entire beach area and specifies the factors that contribute to its formation and characteristics.

Submit
57. On which side of the maritime forest is there evidence of the effects of salt spray on trees and shrubs?

Explanation

The correct answer is the seaward side. The effects of salt spray on trees and shrubs can be observed on the side facing the sea. The salt spray carried by the wind from the ocean can cause damage to vegetation, resulting in stunted growth, leaf discoloration, and even death of plants. This is because salt can accumulate in the soil and interfere with the plant's ability to take up water and nutrients. Therefore, the seaward side of the maritime forest is where evidence of the effects of salt spray on trees and shrubs can be found.

Submit
58. Why does air temperature change more quickly than water temperature?

Explanation

Water has a high specific heat, meaning it requires a large amount of energy to change its temperature. On the other hand, air has a lower density due to the movement of gas molecules. This means that air can heat up or cool down more quickly compared to water.

Submit
59. What is the "fluid threshold" of saltation?

Explanation

The fluid threshold of saltation refers to the wind speed required for sand to begin saltating, which means to be lifted and moved by the wind under direct pressure. This is the point at which the sand particles become airborne and start to bounce and skip along the ground. The fluid threshold is not about maintaining saltation once it has started, how surfaces respond to each other, or wind speeds above 20 mph on the windy side of a dune.

Submit
60. What makes sand accumulate into piles rather than spread out evenly over an area?

Explanation

Sand tends to accumulate into piles rather than spread out evenly over an area because when there is a sufficient reduction of wind energy in the direction that sand drifts in, and there are obstacles such as rock outcrops or stands of vegetation, the wind speed is lowered. This reduction in wind speed allows the sand particles to settle and accumulate in these areas, forming piles. The obstacles act as barriers, disrupting the flow of wind and causing the sand to accumulate in their vicinity.

Submit
61. Identify the three major forces that effects the row of dunes nearest the ocean:

Explanation

The correct answer is "Strong winds, whipping sands, glaring sun." These three forces are the major factors that affect the row of dunes nearest the ocean. Strong winds can shape and move the sand, while whipping sands can erode and reshape the dunes. The glaring sun can also contribute to the drying and shifting of the sand, further affecting the formation and stability of the dunes.

Submit
62. Elevation and slope of the coastal habitats land determine:

Explanation

The elevation and slope of coastal habitats land determine how far the tidal zones extend in a habitat. This is because the elevation and slope affect the reach of the tides, with higher elevations and steeper slopes allowing the tides to penetrate further inland. The tidal zones are the areas that are regularly submerged and exposed by the tides, and their extent is influenced by the topography of the land. Therefore, the elevation and slope of the coastal habitats land directly impact the distance that the tidal zones reach into the habitat.

Submit
63. Identify the six key environmental factors that affect shoreline habitat:  

Explanation

The correct answer is "Six key shoreline environmental factors: climate, water level, salinity, water temperature, air temperature and substrate." This answer includes all the key environmental factors that affect shoreline habitat, such as climate, water level, salinity, water temperature, air temperature, and substrate. These factors play a crucial role in determining the conditions and suitability of the shoreline habitat for various organisms.

Submit
64. What is the 'impact threshold' of saltation?

Explanation

The impact threshold of saltation refers to the wind speed necessary to maintain the movement of sand grains once they have started moving under direct wind pressure. Lower wind speeds are sufficient to maintain sand movement because the impact of saltating grains is enough to knock new sand grains into the air. This means that once saltation has begun, it can continue with lower wind speeds.

Submit
65. Coarse sand settles in the intertidal zone because:

Explanation

Turbulent ocean waves have enough energy to carry coarse sand and deposit it on the shoreline. The force of the waves causes the sediment to be transported and then settled in the intertidal zone. This process is responsible for the accumulation of coarse sand in this area.

Submit
66. On the NC coast the tidal range is between ____ and ____ meters, depending on the general location of the shoreline.

Explanation

The tidal range on the NC coast varies between 0.6 and 1.3 meters, depending on the general location of the shoreline.

Submit
67. IDENTIFY: the barrier island formation step in this diagram:

Explanation

During the peak of glacial covering of the land, the sea level is low. This means that there is less water in the ocean, and as a result, the coastal areas are exposed. The low sea level allows sediment to accumulate in the trenches and river valleys, creating estuaries. This is the first step in the formation of barrier islands because it sets the stage for the subsequent processes of sediment transport and island formation.

Submit
68. IDENTIFY: the barrier island formation step in this diagram:

Explanation

This step describes the process of glacial meltwater flooding the coastal plain lowland and filling trenches and river valleys with fresh water, which in turn leads to the formation of estuaries. This step is important in the formation of barrier islands because it contributes to the deposition of sediment that eventually forms the barrier island spits along the coastal headlands.

Submit
69. What does the presence of a maritime forest indicate about a barrier island?

Explanation

The presence of a maritime forest indicates that the barrier island is wide. Maritime forests are typically found on wide barrier islands where there is enough space for vegetation to grow and thrive. These forests are characterized by trees and shrubs that can withstand the harsh coastal conditions, such as salt spray and high winds. Therefore, the presence of a maritime forest suggests that the island has enough width to support the growth of vegetation and provide a suitable habitat for a diverse range of plant species.

Submit
70. Debris and detritus are deposited ___________________

Explanation

Debris and detritus are deposited at the high tide line because this is the area where the highest point of the tide reaches on the shoreline. As the tide rises, it carries along with it various materials such as seaweed, shells, and other organic matter which get deposited at the high tide line. This area is easily distinguishable as it marks the highest point reached by the tide before it recedes again.

Submit
71. How does water level affect organisms in the subtidal zone?

Explanation

The correct answer explains that organisms in the subtidal zone need to be able to breathe water or hold their breath for long periods of time. This is because the water level in the subtidal zone fluctuates, with organisms being submerged at high tide and exposed to air at low tide. Therefore, they must have adaptations that allow them to survive in both submerged and exposed conditions, such as the ability to extract oxygen from water or hold their breath until the tide returns.

Submit
73. Intertidal beach life is nourished largely by _______________ brought in by ____________.

Explanation

Intertidal beach life relies on the nutrients provided by plankton, which are brought in by the tides. Plankton serve as a food source for many organisms in the intertidal zone, and the regular ebb and flow of the tides helps to distribute these nutrients along the beach. The tides carry plankton from deeper waters to the shore, where they become available as food for various intertidal organisms. This symbiotic relationship between plankton and tides is essential for the nourishment and survival of intertidal beach life.

Submit
74. Ghost crabs are unique organisms that live in deep tunnels with front and back entrances. They rarely leave their burrow during the day. Though they live in the dunes, the female deposits eggs in the ocean and the young develop there. How do ghost crabs breathe?

Explanation

Ghost crabs have gills that need to be moistened with ocean water on a daily basis in order for them to breathe. This suggests that they primarily rely on extracting oxygen from the water through their gills. However, once they come onto land, they switch to breathing air. This adaptation allows them to survive in both aquatic and terrestrial environments.

Submit
75. Maritime forest is critical to the stabilization of an island because it is efficient at retaining two key growth elements.

Explanation

Maritime forests play a crucial role in stabilizing islands due to their ability to retain rainfall and nutrients. Rainfall is important as it helps to provide moisture for the plants and trees in the forest, supporting their growth and survival. Nutrients, on the other hand, are essential for the plants to obtain the necessary minerals and elements for their development. The combination of rainfall and nutrients ensures that the maritime forest can thrive and contribute to the stability of the island ecosystem.

76. The action of ____________________ sweeps larger shell particles and sand across the substrate surface, sometimes causing abrasions or burying plants and animals.

Explanation

Waves have the ability to move larger shell particles and sand across the substrate surface due to their strong force. This movement can sometimes lead to abrasions or burying of plants and animals. Waves can be powerful and their constant motion can cause significant changes in the coastal environment.

77. Oxygen is plentiful in the ocean beach habitat because of which three factors:

Explanation

The correct answer is the wind coming off the ocean, the presence of water coming in with the tides, and in the space between the sand sediment. This is because the wind brings oxygen from the atmosphere, the water coming in with the tides contains dissolved oxygen, and the space between the sand sediment allows for oxygen diffusion from the water into the sediment.

78. Identify the two forces that caused the barrier spits to become islands:

Explanation

Storm events that separated the spits from their sand supply and gradual sea level rise in the high latitudes that flooded the coastal lowlands behind the sand spit dune ridges are the two forces that caused the barrier spits to become islands. The storm events caused the spits to be separated from their source of sand, while the gradual sea level rise flooded the coastal lowlands behind the spits, turning them into islands.

Submit
79. Tides- the twice daily high and low flow of water onto and into a low lying shore area caused by the:

Explanation

The tides are caused by the gravitational pull of both the moon and the sun on Earth. The moon's gravitational force is stronger than the sun's, which leads to the dominant influence of the moon on tides. As the moon orbits around the Earth, it creates a gravitational force that causes the water on the side of the Earth facing the moon to be pulled towards it, creating a high tide. At the same time, there is a high tide on the opposite side of the Earth due to the centrifugal force created by the Earth-moon system. The sun also exerts a gravitational force on Earth, although it is weaker than the moon's. The combined gravitational pull of the moon and the sun causes the twice-daily high and low flow of water, resulting in tides.

80. Why is Oxygen plentiful in the dune habitat?

Explanation

Ocean breezes provide a steady inflow of wind to the dune habitat. This wind carries oxygen molecules from the ocean and disperses them throughout the dune area. As a result, oxygen becomes plentiful in the dune habitat.
