Evaporation: It is a process by which water gets heated and enters into the atmosphere in the form of water vapour.
Condensation: It is a process by which water vapour gets converted into tiny droplets of water or ice.
Humidity: The amount of water vapour present in the atmosphere is known as humidity.
Latent Heat: It is the hidden heat which changes solids into liquids or water vapour, or liquid into vapour without a change in the temperature.
Precipitation: The process by which condensed water vapour falls on the surface of the Earth in various forms like rainfall, snowfall, hail etc.
