Solution

The correct option is A True
Water from all the reservoirs present on land evaporates due to heat. Even plants contribute to evaporation by the process of transpiration. It then exists in the form of water vapour in the atmosphere. The water vapour expands and cools as it goes up. Due to cooling, they form water droplets around a 'nucleus'. Here any dust particle or particulate matter acts as a nucleus around which water molecules gather and condense to form water droplet. These water droplets further condense and form clouds. When the clouds become large and heavy, the water droplets fall down as rain. All of the water that falls on the land does not immediately flow back into the sea. Some of it seeps into the soil and becomes part of the underground reservoir of fresh water.
