Precipitation: Return to Earth
Precipitation is any type of water that falls from clouds to the Earth’s floor. This consists of rain, snow, sleet, and hail. The kind of precipitation is determined by the temperature of the ambiance. When the temperature is above freezing, rain is the most typical type of precipitation. When the temperature is under freezing, snow, sleet, or hail could happen.
Precipitation happens when water droplets or ice crystals in clouds change into too heavy to stay suspended within the air. These droplets or crystals then fall to the bottom as a result of gravity. Rainfall quantities differ considerably relying on atmospheric situations, geographic location, and time of yr. Sure areas of the world expertise heavy rains and others little or no.
Precipitation is the first mechanism by which water returns to the Earth’s floor. It replenishes rivers, lakes, and groundwater reserves. It additionally gives important moisture for crops and animals. Precipitation can also be important to agriculture.
Runoff: The Floor Circulation
When precipitation falls on the Earth’s floor, a few of it’s absorbed by the bottom, whereas the remainder flows over the land floor. This movement known as runoff. The quantity of runoff is determined by a number of elements, together with rainfall depth, the slope of the land, the kind of soil, and the vegetation cowl. Heavy rainfall on steep slopes with impermeable soil will end in excessive quantities of runoff.
