Rain

Keshav Bhatia, Academic Content writer at Edumarz

Rain is an important natural resource, it ensures the continuation of life for almost all plants and animals by providing them water. It is the main reason why water in the atmosphere falls down on earth, enriches life on earth and recharges our water bodies. It is essential for the Earth’s water cycle.

  • When water bodies heat up during the day, they are converted into water vapour and it rises up. Biological activities such as transpiration also produce water vapour.

  • This air gets heated and rises with the water vapour.

  • As the air rises up it expands and cools down.

  • Tiny droplets are formed as the result of this cooling.

  • Dust and other suspended particles act as a nucleus around which droplets form and this also helps facilitate the condensation.

  • When the droplets get big and heavy enough, they fall down in the form of rain.

  • In certain cases, when the temperature of the atmosphere is low/cold enough, snowfall, sleet or hail can be observed.


  • Rainfall patterns are usually decided by wind patterns.

In large parts of India, prevailing wind patterns cause rains by the south-west or north -east monsoons.
