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.

What happens to water molecules when they evaporate?

Back

When water molecules evaporate, they gain energy, move faster, and spread apart, changing from a liquid to a gas.

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

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 runoff?

Back

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

Front

What is groundwater?

Back

Groundwater is water that is stored underground in soil and rock layers, which can eventually return to the surface.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water is transformed into water vapor, usually due to heat.

Front

What role do clouds play in the water cycle?

Back

Clouds are formed by condensed water vapor and are essential for precipitation, as they release water back to the Earth's surface.

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 back into liquid.

Front

What is an example of precipitation?

Back

An example of precipitation is snow.
