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 from the sun.

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds or dew.

Front

What is precipitation?

Back

Precipitation is any form of water that falls from the atmosphere 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 the energy needed for evaporation, driving the water cycle by heating water in oceans, lakes, and rivers.

Front

What is runoff?

Back

Runoff is the flow of water, from rain or melting snow, that moves across the ground and returns to bodies of water, replenishing them.

Front

What is transpiration?

Back

Transpiration is the process by which plants release water vapor into the atmosphere from their leaves.

Front

How does temperature affect evaporation?

Back

Higher temperatures increase the rate of evaporation, as more water molecules gain enough energy to escape into the air.

Front

What is the difference between evaporation and condensation?

Back

Evaporation is the process of water turning into vapor, while condensation is the process of vapor turning back into liquid water.

Front

What is the significance of the water cycle?

Back

The water cycle is essential for maintaining ecosystems, regulating climate, and providing fresh water for all living organisms.
