The Occurrence of Rain

Water is a natural resource that is vital vital for the survival and development of life on Earth. The occurrence of rainfall is strongly influenced by convection in the Earth's atmosphere and oceans. Convection is the transfer of heat by the mass movement of a fluid from one region to another. Water-Water is composed of sea water, river water, waste water, and so are generally undergo a process of evaporation or evaporation due to the help of the hot sun. The water vapor then be floated into the air and eventually continue to move toward the high ceiling with water vapors others.

 
Arriving at the top, the vapors undergo a process commonly referred to as compaction or condensation forming clouds. Moving by wind, the clouds converge and swell and then headed into the earth's atmosphere where the temperature is lower or cool and eventually form ice granules and water. Because it was too heavy and could no longer sustained wind eventually water droplets or ice that falls to the earth's surface, this process is called precipitation process. Due to the lower, resulting in the temperature goes up, the ice / snow will melt, but if the temperature is very low, it will remain a snow fall.
