What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth, involving processes like evaporation, condensation, and precipitation.

Front

What are the main processes of the water cycle?

Back

The main processes of the water cycle are evaporation, condensation, precipitation, infiltration, and runoff.

Front

How does evaporation occur?

Back

Evaporation occurs when water is heated by the sun and changes from a liquid to a gas (water vapor).

Front

What is condensation in the water cycle?

Back

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

Front

What is precipitation?

Back

Precipitation is any form of water that falls from clouds to the Earth's surface, including rain, snow, sleet, and hail.

Front

What role does the sun play in the water cycle?

Back

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

Front

What is groundwater?

Back

Groundwater is water that is stored underground in soil and rock layers, and it is a significant source of freshwater.

Front

How do humans impact the water cycle?

Back

Humans impact the water cycle by redirecting rivers, building dams, using water for various purposes, and polluting water sources.

Front

Where is most of the freshwater stored on Earth?

Back

Most of the freshwater on Earth is stored in freshwater lakes and rivers.

Front

What is runoff?

Back

Runoff is the flow of water over the land surface, often after precipitation, which can lead to rivers and streams.
