Water Cycle Test Practice

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 by which water changes from a liquid to a gas, usually due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

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

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 energy needed for evaporation, driving the water cycle by warming water bodies and causing water to rise into the atmosphere.

Front

What role do clouds play in the water cycle?

Back

Clouds are formed during condensation and are essential for precipitation, as they hold water vapor that eventually falls back to the Earth.

Front

What happens during the process of evaporation?

Back

During evaporation, water molecules gain energy and escape from the surface of a liquid, turning into water vapor.

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 crucial for maintaining the Earth's climate, supporting ecosystems, and providing fresh water for all living organisms.
