The Water Cycle

The water cycle, also known as the hydrologic cycle, is the continuous movement of water on, above, and below the surface of the Earth. It involves the processes of evaporation, condensation, precipitation, and runoff.

Evaporation

Evaporation is the process by which water from bodies of water, such as oceans, lakes, and rivers, is heated by the sun and turns into water vapor, which then rises into the atmosphere.

Condensation

As the water vapor rises into the atmosphere, it cools and condenses to form clouds. This process is known as condensation.

Precipitation

When the clouds become saturated with water vapor, the water droplets or ice crystals fall to the Earth's surface as precipitation. This can take the form of rain, snow, sleet, or hail.

Runoff

After precipitation falls to the ground, it can flow over the surface as runoff, eventually making its way back to bodies of water, where the cycle begins again.

The water cycle is essential for maintaining the Earth's water supply and plays a crucial role in weather patterns and the overall climate of the planet.
