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 where liquid water is heated by the sun and turns into water vapor, rising into the atmosphere.

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 clouds 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 energy needed for evaporation, which helps to form clouds and ultimately leads to precipitation.

Front

What role do clouds play in the water cycle?

Back

Clouds are formed by condensation and are essential for precipitation, as they hold water vapor that eventually falls as rain or snow.

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 happens during the process of precipitation?

Back

During precipitation, water droplets in clouds combine and grow heavy enough to fall to the ground as rain, snow, sleet, or hail.

Front

Why is the water cycle important?

Back

The water cycle is important because it distributes fresh water across the planet, supports ecosystems, and regulates climate.
