The process of changing of water from the liquid state to the gaseous state is called evaporation. It occurs every day in natural and man-made environments. It occurs most often around the areas which are situated near water bodies. It is the most important process in case of water cycle because the water from water bodies goes into atmosphere through the process of evaporation. The rate of evaporation increases with the increase in the temperature.

The amount of water vapor in the air is known as humidity. It can make hot temperatures even more unbearable than they already are. It affects both weather as well as climate. It also affects global climate change. Both low humidity as well as high humidity is harmful for us. Humidity is of two types:- Absolute humidity and Relative humidity.

Hail is a small ball of ice in the atmosphere, especially at night. It is a result of precipitation. It is produced by intense thunderstorms when snow and rain coexists. As the snowflakes fall, liquid water freezes onto them. It forms ice pellets that continue to grow as more droplets accumulate. When the ball of ice becomes so large and heavy, they fall as hailstones.

Cirrus, cumulus, and stratus are the types of cloud. Cirrus clouds are very thin and white in colour. They are formed of ice crystals and give a feathery appearance. They are the highest clouds. Cumulus clouds are generally dense and with sharp outlines, developing vertically in the form of rising mounds, domes or towers, of which the bulging upper parts often resemble a cauliflower. Stratus clouds resemble fog and made up of almost equal layers. Occasionally, they are broken into patches separated by blue sky by the incoming wind. Stratus clouds are grey in colour.
