9. Use the following flow chart to write a paragraph on how rain is formed: (in about 100
words)
[Points: Water from water bodies sucked by sunrays-water vapour formed-vapour rises
high in the sky--becomes cool-condenses--forms tiny particles of water--floats in the air
as clouds-large and heavy particles---clouds fall on earth as rain.)

Answer:
Water from the water body gets evaporated by sun rays and form water vapours which then rises to sky. In the sky they become cool and gets condensed which in result, form tiny water particles. They floats in air and become large by joining with each other and forms cloud. When cloud becomes large and heavy it results yo rain on the earth.
Answer:
Rain is droplets of water that are condensed as a result of evaporation. During the water cycle formation of clouds takes place. Rain is also called precipitation.
Water is absorbed from different water bodies, a large amount of which vaporizes and enters the atmospheric air. Water gets evaporated because of various other biological processes as well. This hot air containing water molecules thus rises above the ground level expands and cools after reaching a suitable height. On cooling, water vapour turns into droplets of water, this process is called condensation. It is facilitated by substances such as dust and other particles suspended in the air which accelerates the process and forms the nucleus for these droplets. The cluster of such droplets clamps together to form huge water masses appearing to us as clouds. Once they grow big and heavy, they fall down to the ground as rain. Hence, they are precipitations. These precipitations are sometimes in the form of snow, hail or sleet if the temperature is low.
