Due to evaporation of water from various water bodies, open fields and transpiration from the surface of leaves, water vapours are formed in the air. As this air moves up, it gets cooler and at certain height, it becomes cool enough for condensation. There, the water vapours present in the air condense into tiny droplets of water. These tiny droplets of water remain floating in the air and appear to us as clouds.

Drought occurs when there is scanty rainfall or no rainfall for a year or more in a particular region. As the lakes and ponds dry up due to continuous evaporation, the water level lowers down. The soil continues to lose water by evaporation and transpiration and ultimately becomes dry. This condition leads to drought.
