Water Cycle

Front

What is evaporation?

Back

Evaporation is the process by which water turns into a gas (water vapor) 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 is runoff?

Back

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

Front

What role does the sun play in the water cycle?

Back

The sun provides the energy needed for evaporation, which is a key part of the water cycle.

Front

What happens to water during evaporation?

Back

During evaporation, water absorbs heat and changes from a liquid to a gas.

Front

Why do droplets fall as precipitation?

Back

Droplets fall as precipitation because they become too heavy for the air to hold.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth.

Front

Does the water cycle have a beginning or an end?

Back

The water cycle has no beginning and no end; it is a continuous process.

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.
