WEATHER QUESTION:
"Why are some clouds dark?"- Max and Logan Sentner

EXPLANATION:
This depends mostly on the density, or thickness, of the cloud. Clouds are made up of tiny water droplets that reflect the sunlight. As the light passes through a cloud, it reflects evenly off of all the droplets making it appear white to our eyes.

As clouds build vertically and get thicker, such as a cumulonimbus cloud, less light can pass through the cloud. This will give it a darker appearance. This is also the reason why the bottom of clouds sometimes appear darker than the top.
