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, and precipitation.

Front

What is evaporation?

Back

Evaporation is the process where liquid water turns into water vapor (gas) 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 that falls from clouds to the Earth's surface, including rain, snow, sleet, and hail.

Front

What role does the sun play in the water cycle?

Back

The sun provides heat that causes evaporation, driving the water cycle.

Front

What happens to water vapor in the atmosphere?

Back

Water vapor rises, cools, and condenses to form clouds.

Front

What is the difference between liquid water and water vapor?

Back

Front

What is the process of water turning from a gas to a liquid called?

Back

The process is called condensation.

Front

What is runoff in the water cycle?

Back

Runoff is the water that flows over the ground and returns to rivers, lakes, and oceans after precipitation.

Front

What is infiltration?

Back

Infiltration is the process by which water soaks into the ground and becomes groundwater.
