Why the clouds are up in the sky?
Interesting. Is there a limit to how high clouds can form in the sky?
Yes, there is a limit to how high clouds can form in the sky. This limit is known as the tropopause, which is the boundary between the troposphere and the stratosphere. Clouds cannot form above this level because the air is too dry and cold for water droplets or ice crystals to group together.
