rain
This is precipitation, part of the water cycle.
airRain are water droplets that fall from the sky.If it is very cold, or there are layers of vary cold air that the rain passes through on the way down, the water droplets can become snow or balls of hail.
how do droplets become heavy enogh so that the droplets fall as rain and snow
Simple answer: They don't. Clouds ARE water - tiny, tiny droplets of water just like fog. If colder air moves into a cloud, it causes there to be even more water droplets forming. When the droplets get close enough together, they start touching and turning themselves into even larger droplets. Then the "even larger" water droplets touch, and make water drops . . . at some point in this process, the water droplets grow large enough that they are too heavy to stay where they are, and then they fall to the ground. This falling to the ground is what we call, "Rain".

condensation
All water droplets in the air is different just like when they fall down.

drizzle
The cold air wedges underneath a large warm airmass. This causes the warm air to rise up and condensate. The action of the water droplets rubbing together produces a static charge which creates lightning in the storm. The water droplets fall as rain.
they get bigger because the water droplets are cold and there is also water vapour in the air which is hotand when they meet the water vapour changes back to water droplets which then combine with the water droplets falling from the thunder cloud!!
Precipitation
Why do the clouds droplets not fall to the earth

Because of gravity! And also because of the weight of the water droplets.
