What is the energy source for the water cycle?

• the sun
• the earth
• water
• the moon

What part of the water cycle does this picture show?

• condensation
• precipitation
• evaporation

What part of the water cycle does this picture show?

• condensation
• precipitation
• evaporation

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.

What is condensation?

• 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.

Which best explains why runoff is important?
