Clouds are made up of water, dust, air, and other particles.

Stratus Clouds are a small, thin, low to the ground cloud.

Cumulus clouds are like Stratus clouds but a bit more dense looking.

Stratocumulus clouds are just a bigger version of the Cumulus clouds. 

Altocumulus clouds are a big group of small clouds really high up in the sky.

Cumulonimbus clouds are the biggest types of clouds and are also the ones that hold the most rain and are what thunderstorms are made of.

Cirrus clouds are a thin wispy cloud. They kind of look like long, flowing hair. They form really high up in the sky

Cirrocumulus clouds are similar to Altocumulus clouds but the clouds in the group are much smaller and these clouds can be found much higher up than Altocumulus clouds.
