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 again through evaporation, condensation, and precipitation.

Front

What is evaporation?

Back

Evaporation is the process where water changes from a liquid to a gas, usually 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 clouds.

Front

What is precipitation?

Back

Precipitation is any form of water that falls from the sky, including rain, snow, sleet, and hail.

Front

What is runoff?

Back

Runoff is the water that flows over the ground surface and returns to rivers, lakes, and oceans after precipitation.

Front

What is water vapor?

Back

Water vapor is the gaseous form of water that is present in the air.

Front

How do clouds form?

Back

Clouds form when water vapor condenses into tiny water droplets or ice crystals in the atmosphere.

Front

What role does the sun play in the water cycle?

Back

The sun provides the heat energy needed for evaporation to occur.

Front

What happens during the evaporation stage of the water cycle?

Back

During evaporation, water from oceans, rivers, and lakes turns into vapor and rises into the atmosphere.

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.
