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 liquid water turns into water vapor (gas) due to heat.

Front

What is condensation?

Back

Condensation is the process where water vapor (gas) cools and changes back into liquid water drops.

Front

What is precipitation?

Back

Precipitation is any form of water that falls from the atmosphere to the Earth's surface, such as rain, snow, sleet, or hail.

Front

What is runoff?

Back

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

Front

What are examples of precipitation?

Back

Examples of precipitation include rain, snow, sleet, and hail.

Front

How does water vapor form in the water cycle?

Back

Water vapor forms through evaporation when heat causes liquid water to change into gas.

Front

What happens during condensation in the water cycle?

Back

During condensation, water vapor cools and changes into tiny water droplets, forming clouds.

Front

What role does the sun play in the water cycle?

Back

The sun provides the heat energy needed for evaporation to occur, driving the water cycle.

Front

What is the difference between evaporation and condensation?

Back

Evaporation is the process of liquid turning into gas, while condensation is the process of gas turning into liquid.
