why does rain fall in drops
Answers
Rains fall in the form of droplets. The main reasons are as follows:
1) When water evaporates as water vapour and goes up in the sky which has a cooler environment, it remains suspended for a limited time.
2) when a certain amount of vapour gets accumulated, it form clouds. The water droplets remain suspended in them.
3) They gradually become heavy, and when they finally cant withstand the gravitational force, they start falling as rain drops.
4) They take the shape of small spheres as spheres have the smallest surface area out of all regular shapes.
why does rain fall in drops?
Rain is the result of condensation of vapour when the air is cooled below the dew point. All the vapour in a cloud cannot condense at the same time and turn into a large pool of water. Pockets of air move up independently and slowly cool till condensation begins and water droplets form. It is believed that most raindrops start out as tiny ice crystals - so tiny that they float down, slowly accreting more moisture on the way; at lower altitudes, the crystals melt into water droplets. In colder climates, the crystals reach the ground as snowflakes.
