The 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, precipitation, and runoff.

Front

What happens during evaporation?

Back

Evaporation is the process where 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 droplets, 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 rivers, lakes, and oceans after precipitation.

Front

What is the correct order of the water cycle?

Back

The correct order is: evaporation, condensation, precipitation, and runoff.

Front

How do clouds form?

Back

Clouds form when water vapor condenses into tiny droplets around dust particles in the air.

Front

What role do oceans play in the water cycle?

Back

Oceans provide a large source of water that evaporates into the atmosphere, contributing to the water cycle.

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.

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.
