Moving water laying down sediment is a process called ____________
Correct Answer
depositionExplanation
Moving water has the ability to transport and carry sediment, such as sand, silt, and clay particles. However, when the water slows down or comes to a stop, it loses its energy and is no longer able to carry the sediment. As a result, the sediment settles and is laid down on the bottom of the body of water. This process is known as deposition.Rate this question:
- 3.
The process in which water vapor changes back into liquids as water vapor cools is called ___________
Correct Answer
condensation
condensationsExplanation
Condensation is the correct answer for this question. When water vapor cools down, it changes back into liquid water through the process of condensation. This occurs when the temperature of the air decreases, causing the water vapor molecules to slow down and come together, forming tiny water droplets. Condensation is an important part of the water cycle and can be observed in everyday situations, such as when droplets form on the outside of a cold glass of water or when clouds form in the sky.Rate this question:
- 4.
____________ is the process that gradually changes water from liquid to water vapor.
Correct Answer
evaporationExplanation
Evaporation is the process that gradually changes water from liquid to water vapor. It occurs when heat energy is applied to water, causing the water molecules to gain enough energy to break free and transform into gas. This process commonly takes place at the surface of bodies of water, such as oceans, lakes, and rivers, as well as from moist soil and plants. Evaporation plays a crucial role in the water cycle, as it is responsible for transferring water from the Earth's surface back into the atmosphere.Rate this question:
- 5.
Water droplets that fall from the clouds to the earth is called
Correct Answer
precipitationExplanation
Precipitation refers to the process in which water droplets fall from the clouds to the Earth's surface. It includes various forms such as rain, snow, sleet, and hail. This natural phenomenon occurs when the moisture in the atmosphere condenses and becomes too heavy to remain suspended in the air. As a result, the water droplets or ice crystals fall to the ground due to the force of gravity. Precipitation is an essential part of the Earth's water cycle and plays a crucial role in replenishing the planet's water resources.Rate this question:
- 6.
The _________ cycle is the constant cycling of water between Earth's surface and the atmosphere through evaporation, condensation and precipitation.
Correct Answer
waterExplanation
The water cycle, also known as the hydrological cycle, refers to the continuous movement of water on Earth's surface and in the atmosphere. It involves various processes such as evaporation, condensation, and precipitation. Water evaporates from bodies of water, such as oceans and lakes, and rises into the atmosphere. It then condenses to form clouds and eventually falls back to the surface as precipitation, which can be in the form of rain, snow, or hail. This constant cycling of water helps maintain the balance of water resources on Earth.Rate this question:
- 7.
________ is water that flows over land and eventually flows into lakes, rivers or streams affeced by the intensity and amount of rain.
Correct Answer
runoff
run offExplanation
Runoff, also known as run off, refers to the water that flows over the land surface and eventually makes its way into lakes, rivers, or streams. It is influenced by the intensity and quantity of rainfall. This water accumulates and moves across the land, picking up pollutants and sediments along the way, before reaching its final destination. The terms "runoff" and "run off" are interchangeable and both refer to the same process of water flowing over the land and into bodies of water.Rate this question:
- 8.
___________ is the wearing away of earth's surface when soil or rock is loosend by wind and water and moved from one place to another.
Correct Answer
Explanation
Erosion is the process by which the earth's surface is gradually worn away through the action of wind and water, causing soil or rock to be loosened and transported from one location to another. This natural phenomenon can occur in various forms such as water erosion, where flowing water carries away sediment, or wind erosion, where wind picks up and transports particles. Erosion plays a significant role in shaping the Earth's landscape over time, creating features like valleys, canyons, and deltas.Rate this question:
- 9.
The wide bends in a stream forms caused when the stream erodes its banks more than the channel depth is called _____________
Correct Answer
meanders
meanderingExplanation
The wide bends in a stream are formed when the stream erodes its banks more than the channel depth. This erosion causes the stream to curve and create meanders. Meanders are characterized by their sinuous shape and are commonly found in low-gradient streams. The continuous erosion and deposition of sediment along the banks of the stream contribute to the formation and evolution of meanders over time.Rate this question:
- 10.
____________ water is water that soaks into the ground and collects in small spaces between bits of soil and rock.
Correct Answer
ground
GroundExplanation
Groundwater is water that infiltrates into the ground and accumulates in the tiny gaps between soil particles and rocks. It is an essential natural resource that is stored underground in aquifers. Groundwater plays a vital role in supplying water for drinking, irrigation, and industrial purposes. It is replenished through precipitation and seepage from rivers and lakes. The term "ground" refers to the Earth's surface, while "Ground" is likely a typographical error as it is capitalized.Rate this question:

The place where a river starts is called the
- A.
Delta
- B.
Expansion
- C.
Headwaters
- D.
Riverstart
Correct Answer
C. HeadwatersExplanation
The place where a river starts is called the headwaters. This is the point where the river begins its journey, usually at the highest elevation or the source of the river. It is the starting point of the river's flow and is often located in mountains or hills. The headwaters are crucial as they determine the size, direction, and characteristics of the river as it continues to flow downstream.Rate this question:

Rivers are useful to saltwater animals because they can use it to ____________
- A.
Keep warm
- B.
Get food
- C.
Nurse their young
- D.
Go on vacation
Correct Answer
C. Nurse their youngExplanation
Rivers are useful to saltwater animals because they can use it to nurse their young. Many marine species, such as fish and crustaceans, have a part of their life cycle that involves migrating to freshwater rivers or estuaries to reproduce and raise their offspring. These rivers provide a suitable environment with lower salinity levels and abundant food sources for the young animals to thrive. The freshwater environment also offers protection from predators that are typically found in the open ocean. Therefore, rivers play a crucial role in the reproductive success and survival of saltwater animals.Rate this question:

Instead of sinking in or evaporating, ___________ flows over the ground surface
Correct Answer
runoff
run offExplanation
When precipitation falls on the ground, it does not always get absorbed or evaporated immediately. Instead, it tends to flow over the ground surface, forming what is known as runoff or run off. This occurs especially when the ground is saturated or unable to absorb the water, or when the precipitation rate exceeds the infiltration capacity of the soil. Runoff can cause erosion, carry pollutants, and contribute to flooding in areas with poor drainage.Rate this question:

Erosion causes soil and rocks to ____________
- A.
Get wet
- B.
Move
- C.
Get bigger
- D.
Get warmer
Correct Answer
B. MoveExplanation
Erosion is the process by which soil and rocks are worn away and transported by wind, water, or ice. As a result of erosion, soil and rocks are moved from one location to another. This movement can occur downhill, along riverbeds, or through the action of wind. Therefore, the correct answer is "move".Rate this question:

Deposition is one way ___________ is left behind my moving water
Correct Answer
sedimentExplanation
Deposition is the process by which sediment is left behind by moving water. When water slows down or loses its energy, it can no longer carry the sediment it was transporting, causing it to settle and be deposited on the ground or at the bottom of a body of water. This can occur in rivers, streams, or even ocean currents, where the sediment gets dropped and accumulates over time.Rate this question:

What happens in a stream as the land levels out?
- A.
Goes slower
- B.
Goes faster
Correct Answer
B. Goes fasterExplanation
As the land levels out, the gradient of the stream decreases, resulting in a decrease in the stream's slope. This decrease in slope leads to a decrease in the stream's velocity, causing it to flow slower. Therefore, the given answer "Goes faster" is incorrect.Rate this question:
