How are clouds formed?
- Clouds are formed by the process of evaporation and condensation.
- Water from the oceans , rivers, lakes, ponds, plants, fields, and other land surfaces evaporates, gets into air, and rises up in the atmosphere.
- At a certain height when the air becomes cooler, water vapour contained in air condenses.
- On condensation, these form water droplets. These water droplets collect and float in air as clouds.
