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, precipitation, and runoff.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas (water vapor) due to heat from the sun.

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 that falls from clouds to the Earth's surface, including rain, snow, sleet, and hail.

Front

What is runoff?

Back

Runoff is the flow of water, usually from rain, that moves across the ground and returns to rivers, lakes, and oceans.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plants and then released as water vapor into the atmosphere.

Front

How does the sun affect the water cycle?

Back

The sun provides the energy needed for evaporation, which is a key part of the water cycle.

Front

What is the role of clouds in the water cycle?

Back

Clouds are formed by condensation and play a crucial role in transporting water vapor and eventually releasing it as precipitation.

Front

What happens during the process of evaporation?

Back

During evaporation, water molecules gain energy from the sun and escape into the air as water vapor.

Front

What is the difference between evaporation and condensation?

Back

Evaporation is the process of water turning into vapor, while condensation is the process of vapor turning back into liquid water.
