Water Cycle and Water Distribution

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.

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

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

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

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

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.

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

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

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.

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