Question

How come rain only comes from dark gray clouds?

In: Earth Science

Answer 1

Clouds are made of water in a gaseous form – the darker they are means they are much more dense, and thus it’s harder to see through them. When they are too full and heavy, they will dispense the water load they contain. if it isn’t ‘Overflowing’ and grey, it won’t reduce it’s water contents.
