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, 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 (water vapor) due to heat.

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, such as rain, snow, sleet, or hail, that falls from the atmosphere to the Earth's surface.

Front

What is transpiration?

Back

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

Front

How does the sun affect the water cycle?

Back

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

Front

What happens during evaporation?

Back

During evaporation, water absorbs heat and changes from a liquid to a gas, rising into the atmosphere.

Front

What role do clouds play in the water cycle?

Back

Clouds are formed by condensed water vapor and are essential for precipitation to occur.

Front

What is run-off in the water cycle?

Back

Run-off is the movement of water, usually from precipitation, across the ground and into bodies of water like rivers and lakes.

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.
