Role of Solar Radiation in Water Cycle

Introduction:
The water cycle is a continuous process that involves the movement of water from the earth's surface to the atmosphere and back. It is powered by solar radiation and plays a crucial role in maintaining the balance of water on Earth.

Evaporation:
The first stage of the water cycle is evaporation. Solar radiation heats the surface of the earth, and water from oceans, lakes, rivers, and other bodies of water turns into water vapor and rises into the atmosphere.

Condensation:
As the water vapor rises, it cools down and condenses into clouds. The clouds are then carried by winds to different parts of the globe.

Precipitation:
The third stage of the water cycle is precipitation. Clouds release their moisture in the form of rain, snow, or hail, which falls to the earth's surface.

Infiltration and Runoff:
The final stage of the water cycle is infiltration and runoff. Some of the precipitation is absorbed by the ground and becomes groundwater, while the rest runs off into rivers and streams, eventually making its way back to the oceans.

Conclusion:
Solar radiation is essential for the water cycle to occur. Without it, the earth's surface would not be heated, and water would not evaporate into the atmosphere, leading to a severe water shortage. Therefore, it is crucial to understand the role of solar radiation in the water cycle and how it affects the global climate.
