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, precipitation, and runoff.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, usually 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, such as rain, snow, sleet, or hail, that falls from clouds to the Earth's surface.

Front

What is runoff?

Back

Runoff is the flow of water that occurs when excess water from rain, melting snow, or other sources flows over the ground and returns to bodies of water.

Front

What is infiltration?

Back

Infiltration is the process where water soaks into the soil or porous rock from the surface.

Front

What is transpiration?

Back

Transpiration is the process by which plants release water vapor into the atmosphere as a waste product.

Front

How does temperature affect evaporation?

Back

Warm water evaporates quicker than cold water because heat provides energy for water molecules to escape into the air.

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 significance of the water cycle?

Back

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