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 by which water changes from a liquid to a gas (water vapor) due to heat.

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 clouds to the Earth's surface.

Front

What role does temperature play in precipitation?

Back

Temperature affects the form of precipitation; warmer temperatures can lead to rain, while colder temperatures can lead to snow.

Front

What is convection?

Back

Convection is the movement of warmer, less dense air rising and cooler, denser air sinking, which helps transfer heat in the atmosphere.

Front

How does the Sun's energy reach Earth?

Back

The Sun's energy reaches Earth through radiation, which is the transfer of energy in the form of electromagnetic waves.

Front

What is run-off in the water cycle?

Back

Run-off is the movement of water, usually from precipitation, across the ground and into bodies of water.

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 sequence of processes in the water cycle?

Back

The correct sequence is Evaporation, Condensation, Precipitation.
