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 is evaporation?

Back

Evaporation is the process where liquid water heats up and changes into water vapor, rising into the atmosphere.

Front

What is condensation?

Back

Condensation is the process where water vapor cools off 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 clouds to the Earth's surface.

Front

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

Back

The stratosphere contains the ozone layer, which protects living things from harmful UV radiation, but it is not directly involved in the water cycle.

Front

What is the troposphere?

Back

The troposphere is the lowest layer of the atmosphere where weather occurs and where most of the water vapor is found.

Front

What is the exosphere?

Back

The exosphere is the outermost layer of the atmosphere where unmanned satellites orbit the Earth.

Front

What is the ozone layer?

Back

The ozone layer is a region of the stratosphere that contains a high concentration of ozone (O3) and protects the Earth from the Sun's harmful ultraviolet radiation.

Front

What happens during the process of evaporation?

Back

During evaporation, water absorbs heat energy, causing it to change from a liquid to a gas (water vapor).

Front

What is the sequence of the water cycle processes?

Back

The correct sequence is Evaporation, Condensation, Precipitation.
