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 again through evaporation, condensation, and precipitation.

Front

What is evaporation?

Back

Evaporation is the process where water changes from a liquid to a gas, usually 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 the energy needed for evaporation, driving the water cycle.

Front

What is transpiration?

Back

Transpiration is the process by which plants release water vapor into the air through their leaves.

Front

What happens to water molecules during evaporation?

Back

During evaporation, water molecules gain energy, move faster, and spread apart, turning from liquid to gas.

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.

Front

What is the main source of energy for the water cycle?

Back

The main source of energy for the water cycle is the sun.

Front

How do clouds form?

Back

Clouds form when water vapor in the air cools and condenses into tiny water droplets.
