What keeps a cloud suspended in the sky?

The answer is quite simple: clouds are very light. Even though
they contain many tons of water, they are still composed of tiny
water droplets and ice particles that are too small to feel the
effects of gravity, so they float with the surrounding air.
Atmospheric updrafts also keep clouds afloat by countering the
small amount of gravity pulling them down. Clouds generally form,
survive and grow in air that is moving upward, allowing moist wet
air to reach cold dry air and cause condensation.
So, even though clouds do contain a lot of water, they are in
the form of tiny droplets that are spread out for miles, which are
so small that the effect of gravity on them is negligible. That is
why clouds float in the sky.

How rains are caused?

Rain is caused by the evaporation of water. The sun evaporates
the water up into the sky and it gets stored in the clouds. It does
this everyday and soon the clouds start to get heavy because of the
water they carry and once it gets to full it starts to rain. Oh yes
the air up in the sky is getting more and more cold and the clouds
are starting to cover up the sun's light.
