The water cycle, also known as the hydrological cycle, is the continuous process through which water circulates in the environment. It involves the following key processes:
-
Evaporation: Water from oceans, lakes, and rivers is heated by the sun and turns into water vapor, rising into the atmosphere.
-
Condensation: As the water vapor rises, it cools and condenses to form clouds in the atmosphere.
-
Precipitation: When the clouds become saturated with water vapor, precipitation occurs in the form of rain, snow, sleet, or hail, bringing water back to the Earth's surface.
-
Runoff: Some of the precipitation flows over the land as runoff, eventually reaching rivers, lakes, and oceans.
-
Infiltration: Some of the precipitation seeps into the ground, replenishing groundwater reserves.
-
Transpiration: Plants absorb water from the soil through their roots and release excess water vapor through their leaves in a process called transpiration.
This continuous cycle of evaporation, condensation, precipitation, runoff, infiltration, and transpiration ensures the availability of water on Earth and plays a crucial role in sustaining life and ecosystems.
