Formation of rain. ( Short note 5 marks.)

Dear Student,

Formation of rain is based on the physical phenomena of evaporation and condensation and is an important part of the water cycle.

Water is present in the atmosphere, on land, in the ocean and even underground. It gets used through what the water cycle. In this cycle water changes from liquid, solid and gas (water vapour).

By evaporation, the water in liquid form from the top of oceans,lakes and rivers is converted to gaseous form, known as water vapour. This vapour can also be from snow and ice too.

The water vapour rises in the atmosphere and there it cools down and forms tiny water droplets through condensation. These then turn into clouds. When the water droplets combine together, they grow bigger and are too heavy to stay up there in the air. This is when they will fall to the ground as rain, or maybe snow or hail by gravity.

Hope it helps.

Regards

HOW RAIN IS FORMED The oceans are the chief source of rain, but lakes and rivers also contribute to it. The Sun’s heat evaporates the water. It remains in the atmosphere as an invisible vapor until it condenses, first into clouds and then into raindrops. Condensation happens when the air is cooled. Air cools either through expansion or by coming into contact with a cool object such as a cold landmass or an ice-covered expanse. When air passes over… Thus rain is formed.
