explain role of air in bringing rain
Water bodies such as oceans, lakes, rivers etc are heated during the day time as a result large amount of water evaporates and goes into the air. This air also gets heated. The hot air rises up carrying the water vapour with it. As the air rises, it expands and cools. This cooling causes the water vapour in the air to condense in the form of tiny droplets. This condensation of water is facilitated if some particles could act as the ‘nucleus’ for these drops to form around. Once the water droplets are formed, they grow bigger by the ‘condensation’ of these water droplets. When the drops have grown big and heavy, they fall down in the form of rain.Winds also play an important role in the rainfall patterns.
