An Overview Evaporation in the Water Cycle
The water cycle, also known as the hydrologic cycle, consists of the evaporation of water, snow and ice from various sources on land and sea in a continuous cycle. Evaporation is the first stage in this cycle, and its rate is governed by three important factors:
1. Temperature – the evaporation increases with temperature.
2. Wind – the higher the velocity of the wind, the more water is evaporated
3. Humidity- a low humidity enhances the evaporation rate.
The water is evaporated by the sun, forming vapor that rising up eventually forms the clouds. As the clouds rise higher, the vapor condenses and falls as precipitation, rain, sleet, snow or hailstones depending on the altitude and temperature.
