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 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

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

How does the Sun affect the water cycle?

Back

The Sun heats water in rivers, lakes, and oceans, causing evaporation, which is the first step in the water cycle.

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, while transpiration is the release of water vapor from plants.

Front

What is an example of precipitation?

Back

Rain is a common example of precipitation, but it can also include snow, sleet, and hail.
