Front

What is dew?

Back

Dew is water droplets that form on cool surfaces at night when water vapor condenses.

Front

What causes evaporation to happen faster?

Back

Evaporation happens faster on hot days because heat increases the energy of water molecules.

Front

What is the role of the sun in the water cycle?

Back

The sun provides the energy needed for evaporation to occur.

Front

What happens to water when it freezes?

Back

When water freezes, it changes from a liquid to a solid, forming ice.

Front

What is the difference between liquid water and water vapor?
