Water Cycle and Water Distribution

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 stages like evaporation, condensation, precipitation, and runoff.

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 water vapor?

Back

Water vapor is the gaseous form of water that is present in the air.

Front

What happens during evaporation?

Back

Evaporation is the process where liquid water is heated and changes into water vapor, rising into the atmosphere.

Front

What is condensation?

Back

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

Front

What is runoff?

Back

Runoff is the flow of water, usually from rain, that moves over the ground and eventually reaches bodies of water like rivers, lakes, and oceans.

Front

Where does runoff typically end up?

Back

Runoff can end up in ponds, streams, rivers, and other bodies of water.

Front

What role do clouds play in the water cycle?

Back

Clouds form during condensation and are essential for precipitation, as they hold water vapor that eventually falls as rain or snow.

Front

What is the difference between evaporation and transpiration?

Back

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

Front

What is the significance of the water cycle?

Back

The water cycle is crucial for maintaining the Earth's water supply, supporting ecosystems, and regulating climate.
