Why do clouds turn gray when it’s about to rain?
In: Earth Science
Hold up a tissue to a lamp. You can see through it, hold up two tissues to a lamp, you can still kinda see through it, but it’s a lot darker.
Clouds are made up of water vapor. A little bit of water vapor is see through. A little more looks white/ like a cloud. If you have a whole lot of water vapor, like right before it’s about to rain, it looks grey.
The clouds are thicker/ denser with more moisture in them. This blocks more sunlight passing through, and as a result, they look darker.
