Water Cycle

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, and precipitation.

Front

What is evaporation?

Back

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

Front

What is condensation?

Back

Condensation is the process where water vapor in the air cools down 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 is runoff?

Back

Runoff is the water that flows over the ground surface and returns to bodies of water, such as rivers, lakes, and oceans.

Front

How does temperature affect evaporation?

Back

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

Front

What role does the sun play in the water cycle?

Back

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

Front

What happens to water vapor in the atmosphere?

Back

Water vapor can cool and condense to form clouds, or it can rise higher into the atmosphere.

Front

What is the difference between evaporation and transpiration?

Back

Evaporation is the process of water turning into vapor from surfaces like lakes, while transpiration is the release of water vapor from plants into the air.

Front

What is the significance of the water cycle?

Back

The water cycle is essential for maintaining the Earth's water supply, supporting ecosystems, and regulating climate.
