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

Front

What role does the sun play in the water cycle?

Back

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

Front

What are clouds made of?

Back

Clouds are made of tiny water droplets or ice crystals that form when water vapor condenses.

Front

What is runoff?

Back

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

Front

What is transpiration?

Back

Transpiration is the process by which plants release water vapor into the air from their leaves.

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.

Front

What happens during the condensation process?

Back

During condensation, water vapor cools and forms tiny droplets, which cluster together to create clouds.
