Water Cycle Review

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 liquid water turns into water vapor and enters the atmosphere, usually due to heat from the sun.

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 water is absorbed by plants and then released as water vapor into the atmosphere.

Front

Does water evaporate from oceans contain salt?

Back

No, when water evaporates from oceans, the salt remains in the ocean; only pure water vapor enters the atmosphere.

Front

What is the role of the sun in the water cycle?

Back

The sun provides the energy needed for evaporation, driving the water cycle by heating water in oceans, lakes, and rivers.

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

Can the water cycle be considered a closed system?

Back

Yes, the water cycle is often considered a closed system because the total amount of water remains constant, cycling through different forms.

Front

What is the significance of the water cycle for the environment?

Back

The water cycle is crucial for maintaining ecosystems, regulating climate, and providing fresh water for plants, animals, and humans.
