Water Cycle

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth.

Front

What is evaporation?

Back

Evaporation is the process where water changes from a liquid to a gas, usually when it is heated.

Front

What is condensation?

Back

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

Front

What is precipitation?

Back

Precipitation is any form of water that falls from the sky, such as rain, snow, sleet, or hail.

Front

What is dew?

Back

Dew is water vapor that has condensed into tiny droplets on cool surfaces, like grass.

Front

What is water vapor?

Back

Water vapor is water in its gas form, which is invisible and can be found in the air.

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 role of the sun in the water cycle?

Back

The sun provides heat that causes water to evaporate, starting the water cycle.

Front

What is the difference between evaporation and boiling?

Back

Evaporation occurs at any temperature, while boiling happens at a specific temperature when water reaches its boiling point.

Front

How does temperature affect evaporation?

Back

Higher temperatures increase the rate of evaporation because heat gives water molecules more energy to escape into the air.
