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 again through evaporation, condensation, and precipitation.

What is evaporation?

Back

Evaporation is the process where water is heated by the sun, turning it from a liquid into water vapor or steam, which rises into the air.

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 the part of the water cycle when clouds become heavy and release water in the form of rain, snow, sleet, or hail.

Front

What role does the sun play in the water cycle?

Back

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

Front

What is runoff?

Back

Runoff is the water that flows over the ground and returns to rivers, lakes, and oceans, helping to replenish water sources.

Front

What happens during the process of transpiration?

Back

Transpiration is the process where plants release water vapor into the air from their leaves, contributing to the water cycle.

Front

What is the difference between evaporation and transpiration?

Back

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

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.
