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, precipitation, and runoff.

Front

What is evaporation?

Back

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

Front

What is condensation?

Back

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

Front

What is precipitation?

Back

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

Front

What is transpiration?

Back

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

Front

What role does the sun play in the water cycle?

Back

The sun provides heat energy that drives the processes of evaporation and helps to warm the atmosphere.

Front

What is runoff?

Back

Runoff is the flow of water, from rain or melting snow, that moves across the ground and returns to rivers, lakes, and oceans.

Front

What is groundwater?

Back

Groundwater is water that is stored underground in soil and rock layers, which can be accessed through wells.

Front

What is the difference between evaporation and transpiration?

Back

Evaporation is the process of water turning into vapor from surfaces like lakes and rivers, while transpiration is the release of water vapor from plants.

Front

What happens during the process of sublimation?

Back

Sublimation is the process where ice or snow changes directly into water vapor without first becoming liquid water.
