CH 7.1-7.2 Review: The Role of Water + The Water Cycle

Front

What happens during evaporation?

Back

Evaporation occurs when the sun heats up water and turns it into vapor.

Front

What force is responsible for bringing water downwards in infiltration, precipitation, and run-off?

Back

Gravity is responsible for bringing water downwards.

Front

What percentage of the Earth's water is saltwater?

Back

97% of the Earth's water is saltwater.

Front

What is transpiration?

Back

Transpiration is when a plant absorbs water through its roots and releases water vapor through its leaves.

Front

What is the Water Cycle?

Back

The Water Cycle is the movement of water between the atmosphere, land, oceans, and living things.

Front

What is condensation?

Back

Condensation is the process where water vapor turns into liquid water due to a decrease in temperature.

Front

What is precipitation?

Back

Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from the atmosphere to the Earth's surface.

Front

What role does the sun play in the water cycle?

Back

The sun provides the energy needed for evaporation to occur.

Front

What is infiltration?

Back

Infiltration is the process by which water on the ground surface enters the soil.

Front

What is run-off?

Back

Run-off is the flow of water that occurs when excess water from rain or melting snow flows over the ground and returns to bodies of water.
