Evaporation: When water evaporates from land and other water bodies, it changes into water vapour, which is the most important form of moisture in the atmosphere. Water can change from one form to another by absorbing or giving out heat. During the day, water bodies on the earth absorb heat and some of the water changes into water vapour and goes into the atmosphere. The process by which water chances into water vapour is known as evaporation.
The rate of evaporation is highest on a hot, windy and dry day and the lowest on a cold and wet day.
Humidity: The amount of water vapour present in the atmosphere is known as humidity. Humidity decreases in winter and increases in summer and rainy seasons. It also decreases as we go higher into the atmosphere. When it is hot we sweat and when this sweat evaporates we feel cool. But when the humidity is high in the atmosphere, the rate of evaporation is reduced and the sweat does not evaporate. This makes us feel hot and uncomfortable. At a particular temperature, the ratio between the actual amount of water vapour present in the air and the maximum capacity of the air to hold moisture at the same temperature is its relative humidity. It always expressed in percentage. Condensation: As the moist air rises up, it becomes cool and the water vapour changes into small drops of water. This process is known as condensation. Dew, fog, frost and clouds are the important forms of condensation.
