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 again through evaporation, condensation, precipitation, and collection.

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

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas or vapor, usually due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process by which 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 the main source of energy for the water cycle?

Back

The main source of energy for the water cycle is the Sun.

Front

What happens to a puddle when the sun shines on it?

Back

The puddle evaporates, turning from liquid water into water vapor.

Front

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

Back

The ocean acts as a major reservoir of water, providing moisture that evaporates into the atmosphere.

Front

How do clouds form?

Back

Clouds form when water vapor in the air cools and condenses into tiny water droplets or ice crystals.

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.
