Back

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

Front

What role does the sun play in the water cycle?

Back

The sun provides the energy needed for evaporation, driving the water cycle.

Front

What happens to a puddle on a sunny day?

Back

On a sunny day, a puddle can evaporate due to the heat from the sun.

Front

What is the difference between evaporation and transpiration?

Back

Evaporation is the process of water turning into vapor from surfaces like lakes and puddles, while transpiration is the release of water vapor from plants.

Front

What is the process of water returning to the Earth after condensation?

Back

The process of water returning to the Earth after condensation is called precipitation.

Front

What is the main source of water for the water cycle?

Back

The main source of water for the water cycle is the oceans, lakes, and rivers.
