Sand dune habitats form by____________
-
Sand dune habitats form by wind transport of sand and the growth of stabilizing vegetation.
-
Sand dune habitats form by wind transport of sand captured by detritus along the strand line.
-
Sand dune habitats form by onshore winds transporting sand from the nearshore sandbar.
-
Sand dune habitats form by onshore winds transporting sand from the berm.
Correct Answer
A. Sand dune habitats form by wind transport of sand and the growth of stabilizing vegetation.Explanation
Sand dune habitats form through a combination of wind transport of sand and the establishment of stabilizing vegetation. The wind carries sand particles and deposits them in certain areas, forming dunes. Over time, plants begin to grow in these areas, their roots helping to stabilize the sand and prevent further erosion. This process creates a unique habitat that is able to support a variety of specialized plant and animal species.Rate this question:

The wind velocity necessary to initiate sand movement is about __________mph.
-
The wind velocity necessary to initiate sand movement is about 10 mph
-
The wind velocity necessary to initiate sand movement is about 15 mph
-
The wind velocity necessary to initiate sand movement is about 15-25 mph
-
The wind velocity necessary to initiate sand movement is about 35 mph
Correct Answer
A. The wind velocity necessary to initiate sand movement is about 10 mphExplanation
The correct answer is 10 mph because this is the lowest wind velocity mentioned among the options. It suggests that sand movement can be initiated at a relatively low wind speed.Rate this question:

Sand dune tidal litter includes:
-
Sand dune tidal litter includes: decomposing grasses and organism remains.
-
Sand dune tidal litter includes: cordgrass (spartina) and organism remains.
-
Sand dune tidal litter includes: decomposing grasses, salt spray and organism remains.
-
Sand dune tidal litter includes: decomposing grasses and ghost crab remains.
Correct Answer
A. Sand dune tidal litter includes: decomposing grasses and organism remains.Explanation
Sand dune tidal litter refers to the debris and organic matter that accumulates on sand dunes along the shoreline. This can include decomposing grasses and remains of various organisms. The correct answer states that sand dune tidal litter includes decomposing grasses and organism remains, which accurately describes the typical composition of this type of litter.Rate this question:

Dunes are made of finer sands because______________
-
Dunes are made of finer sands because only the smallest grains of beach sand usually move.
-
Dunes are made of finer sands because only silt grains can be moved.
-
Dunes are made of finer sands because only finer sand is found at the berm.
-
Dunes are made of finer sands because finer sands form mounds in which dune plants can take root.
Correct Answer
A. Dunes are made of finer sands because only the smallest grains of beach sand usually move.Explanation
Dunes are made of finer sands because only the smallest grains of beach sand usually move. This is because the larger grains are too heavy to be easily lifted and transported by wind. As the wind blows, it picks up and carries the smaller sand grains, allowing them to accumulate and form dunes. Therefore, dunes are composed of finer sands, as the larger grains tend to remain stationary on the beach.Rate this question:

Vegetation at the high tide line or in a dune increases sand accumulation by____________
-
Vegetation at the high tide line or in a dune increases sand accumulation by reducing the wind velocity.
-
Vegetation at the high tide line or in a dune increases sand accumulation by increasing the wind velocity.
-
Vegetation at the high tide line or in a dune increases sand accumulation by reducing wave turbulence.
-
Vegetation at the high tide line or in a dune increases sand accumulation by reducing tide turbulence.
Correct Answer
A. Vegetation at the high tide line or in a dune increases sand accumulation by reducing the wind velocity.Explanation
Vegetation at the high tide line or in a dune increases sand accumulation by reducing the wind velocity. When there is vegetation present, it acts as a barrier that slows down the wind, preventing it from carrying away the sand particles. This allows the sand to settle and accumulate in the area, leading to increased sand accumulation.Rate this question:

Water supply is scarce on the frontal dune. How do dune plants hydrate?
-
Plants hydrate by capturing moisture from rainfall and using their deep root system to reach the water table below the dunes.
-
Plants hydrate from the tides at high tide and use their deep root system to reach the low tide line below the dunes.
-
Plants hydrate by using their deep root system to reach deep into the dunes.
-
Plants hydrate by capturing moisture from detritus at the high tide strand line.
Correct Answer
A. Plants hydrate by capturing moisture from rainfall and using their deep root system to reach the water table below the dunes.Explanation
Dune plants hydrate by capturing moisture from rainfall and utilizing their deep root system to access the water table beneath the dunes. This means that they are able to obtain water from the precipitation that falls onto the dunes, and their extensive root system allows them to reach deep into the ground to access the water stored in the water table.Rate this question:

What provides the main source of nutrients on frontal dunes?
-
Salt spray provides the main source of nutrients on frontal dunes.
-
Detritus provides the main source of nutrients on frontal dunes.
-
Sea oats provides the main source of nutrients on frontal dunes.
-
Oxygen provides the main source of nutrients on frontal dunes.
Correct Answer
A. Salt spray provides the main source of nutrients on frontal dunes.Explanation
Salt spray provides the main source of nutrients on frontal dunes. Salt spray contains dissolved minerals and nutrients that are carried by ocean waves and deposited on the dunes. These nutrients are essential for the growth and survival of plants and other organisms in this harsh coastal environment. The salt spray also helps to maintain the moisture levels in the sand, which is important for the survival of dune vegetation. Therefore, salt spray plays a crucial role in providing the main source of nutrients for frontal dunes.Rate this question:

Why is oxygen plentiful in the sand dune habitat?
-
Oxygen is plentiful in the sand dune habitat because of wind.
-
Oxygen is plentiful in the sand dune habitat because of the abundance of plants.
-
Oxygen is plentiful in the sand dune habitat because of the plant and animal life.
-
Oxygen is plentiful in the sand dune habitat because of salt spray and plants.
Correct Answer
A. Oxygen is plentiful in the sand dune habitat because of wind.Explanation
Wind plays a crucial role in providing oxygen in the sand dune habitat. The constant movement of air helps in the circulation of oxygen, ensuring a constant supply. Additionally, wind also helps in dispersing oxygen from the surrounding areas, contributing to the overall abundance of oxygen in the sand dune habitat.Rate this question:

Correct Answer
A. What two things does the deep root system of American beach grass and sea oats help these plants avoid? a. surface heat b. evaporationExplanation
The deep root system of American beach grass and sea oats helps these plants avoid surface heat and evaporation. The deep roots allow the plants to access water from deeper soil layers, reducing their reliance on surface water sources and minimizing the risk of evaporation. Additionally, the deep roots help to anchor the plants firmly in the ground, providing stability and preventing them from being uprooted by strong winds or wave turbulence.Rate this question:
