HOW DOES PRECIPITATION AFFECT THE WATERSHED?

The water from rain runs off the land after heavy rainfall or small showers. This rainwater reaches the surface of the earth and enters the water cycle.

The water cycle is an exchange of water molecules through the processes of evaporation, condensation, infiltration and precipitation. Evaporation is the loss of water molecules from the land surface and waterbodies. It supplies the moisture in the atmosphere. This moisture content is known as humidity. Moisture droplets gather together in the atmosphere where they condense around particles of dust or other substances. Droplets become heavy, and eventually precipitation (rain) occurs.
