Water Cycle

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, and precipitation.

Front

What process causes water to change from liquid to vapor?

Back

Evaporation is the process that causes water to change from liquid to vapor, usually due to heat from the sun.

Front

What is condensation in the water cycle?

Back

Condensation is the process where water vapor cools and changes back into liquid water, forming droplets.

Front

What are clouds made of?

Back

Clouds are made of tiny droplets of water or ice crystals that form when water vapor condenses in the atmosphere.

Front

What is precipitation?

Back

Precipitation is any form of water, such as rain, snow, sleet, or hail, that falls from clouds 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, which is the first step in the water cycle.

Front

What happens to water vapor when it rises in the atmosphere?

Back

As water vapor rises, it cools and condenses to form clouds.

Front

What is runoff in the water cycle?

Back

Runoff is the flow of water, from rain or melting snow, that moves over the ground and returns to rivers, lakes, and oceans.

Front

What is transpiration?

Back

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

Front

How do clouds form?

Back

Clouds form when water vapor in the air cools and condenses into tiny water droplets or ice crystals.
