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 happens during 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.

Front

What is precipitation?

Back

Precipitation is any form of water that falls from the atmosphere to the Earth's surface, such as rain, snow, sleet, or hail.

Front

What is transpiration?

Back

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

Front

What is run-off?

Back

Run-off is the water that flows over the ground and returns to oceans, rivers, and lakes after precipitation.

Front

How much of the Earth's surface is covered by water?

Back

About 75% of the Earth's surface is covered by water.

Front

What role does the sun play in the water cycle?

Back

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

Front

What is the difference between evaporation and transpiration?

Back

Evaporation is the process of water turning into vapor from surfaces like lakes and rivers, while transpiration is the release of water vapor from plants.

Front

What is the significance of the water cycle?

Back

The water cycle is essential for maintaining life on Earth, regulating climate, and supporting ecosystems.
