Water Cycle

Front

What is the water cycle?

Back

The water cycle is the constant movement of water between the Earth and the atmosphere, involving processes like evaporation, condensation, and precipitation.

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, forming droplets.

Front

What is precipitation?

Back

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

Front

What is water vapor?

Back

Water vapor is water in its gas form, which is invisible and present in the air.

Front

When does water evaporate fastest?

Back

Water evaporates fastest on a hot day because heat increases the energy of water molecules.

Front

What happens to water when it freezes?

Back

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

Front

What happens to water when it boils?

Back

When water boils, it changes from a liquid to a gas, creating steam.

Front

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

Back

The sun provides the heat energy needed for evaporation to occur in the water cycle.

Front

What is the difference between liquid water and water vapor?

Back

Liquid water is water in its liquid form, while water vapor is water in its gas form.
