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. It includes processes like evaporation, condensation, and precipitation.

Front

What happens during 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 (gas) cools down 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 water vapor?

Back

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

Front

How does temperature affect evaporation?

Back

Evaporation happens faster on hot days because heat gives energy to the water molecules, allowing them to escape into the air.

Front

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

Back

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

Front

What is the difference between evaporation and boiling?

Back

Evaporation occurs at any temperature when water changes to gas, while boiling happens at a specific temperature (100°C or 212°F at sea level).

Front

What is the process of water turning into ice called?

Back

The process of water turning into ice is called freezing.

Front

What is melting?

Back

Melting is the process where ice (solid) changes back into liquid water when it is heated.
