Hydrosphere and Water Cycle Checkpoint

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.

Front

What process occurs when water changes from a liquid to a gas?

Front

What happens when water vapor in clouds becomes too heavy?

Back

Back

Transpiration is the process by which water is absorbed by plants and then released as water vapor into the atmosphere.

Front

What is the main source of Earth's freshwater?

Back

The main source of Earth's freshwater is glaciers and ice caps.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves through the environment, including evaporation, condensation, precipitation, and collection.

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is run-off?

Back

Run-off is the water that flows over the ground surface and returns to bodies of water, such as rivers, lakes, and oceans.

Front

What role do clouds play in the water cycle?

Back

Clouds are formed by condensation and are essential for precipitation, returning water to the Earth's surface.
