Water vapor in the air cools.

Snow flakes accumulate in the upper atmosphere and form light fluffy clouds.

Hot air rises and keeps on adding air to it until it clumps.

Hail and snow defrost as it gets higher in the atmosphere, this causes their structure to break and form clouds.

Once water vapor turns into liquid drops, those drops cling to the particles of dust around them and gradually press together.
