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 the main source of energy for the water cycle?

Back

The Sun is the main source of energy for the water cycle, providing the heat needed for evaporation.

Front

What happens during evaporation in the water cycle?

Back

Evaporation is the process where water changes from a liquid to a gas (water vapor) due to heat.

Front

Why do clouds form high in the sky?

Back

Clouds usually form high in the sky because it is cold enough there for the water vapor to condense into tiny water droplets.

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 is sleet?

Back

Sleet is a mixture of rain and snow that occurs when rain freezes as it falls to the ground.

Front

What role does gravity play in the water cycle?

Back

Gravity pulls precipitation down to the Earth's surface, allowing water to flow into rivers, lakes, and oceans.

Front

What is condensation in the water cycle?

Back

Condensation is the process where water vapor cools and changes back into liquid water, forming clouds.

Front

How does the Sun affect the water cycle?

Back

The Sun heats water in oceans, lakes, and rivers, causing it to evaporate and enter the atmosphere as water vapor.

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.
