• 3%
• 23%
• 77%
• 97%

How does the amount of water circulating in the water cycle change?

• The amount of water remains constant

• The amount of water increases each time it rains

• The amount of water decreases and then increases each day

• The amount of water decreases every time evaporation occurs

What is evaporation?

• The part of the water cycle when the sun heats up water, turning it from a liquid into water vapor or steam. It rises from the ground into the air.
• The part of the water cycle when the water vapor in the air gets cold. The water turns back into a liquid and forms clouds.
• The part of the water cycle when clouds get heavy and can no longer hold the liquid water. This causes the water to fall from the sky to the earth as rain, snow, sleet, or hail.
