Question

how clouds formed? when do the water droplet fall down as rain

Answer 1

As the water vapor rises in the atmosphere it cools, forming tiny water droplets high in the sky by a process called condensation. Those water droplets make up clouds. If they grow large enough they eventually become too heavy to stay in the air, falling to the ground as rain, snow, and other types of precipitation.
