Why are the tops of clouds all poofy and fun, but the bottoms are totally flat and boring?
In: Physics
Air gets colder as you go up.
Clouds form when invisible water vapour rizes and gets cold enough to turn into droplets, making the cloud.
This happens at a specific distance from the ground (altitude), making the bottom of the cloud flat (and boring).
Further up, the cloud can grow in fun shapes and sizes. It also starts to get cold enough for the water vapour/ droplets to freeze into poofy ice. Making it a cool white colour.
