4.8B 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 process describes water turning into vapor?

Back

Evaporation is the process where water is heated by the sun and changes from liquid to gas (vapor).

Front

What is condensation in the water cycle?

Back

Condensation is the process where water vapor cools and changes back into liquid water, forming clouds or dew.

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 role do plants play in the water cycle?

Back

Plants contribute to the water cycle through transpiration, where they 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, warming the water and turning it into vapor.

Front

What is dew?

Back

Dew is water droplets that form on surfaces when water vapor in the air cools and condenses into liquid water.

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 process of evaporation?

Back

During evaporation, liquid water is heated and changes into water vapor, rising into the atmosphere.

Front

What is the significance of the water cycle?

Back

The water cycle is essential for maintaining ecosystems, providing fresh water, and regulating climate.
