Cirrus clouds are wispy, horse hair like clouds that are often a sign of changing weather. They are made entirely of ice crystals and found high up in the atmosphere.

Cirrocumulus are high patches of lumpy clouds, often very tightly knit together. These clouds aren't like the other ones in it's height category, as instead of ice, there's still liquid water present. However, the water at this altitude really wants to freeze into either cirrostratus or cirrus clouds so these don't often last very long.

Cirrostratus clouds are difficult to spot, not out of rarity, but transparency. These clouds look like a layer of fog really high up, often with little texture other than the occasional waviness. These often produce halos and other optical phenomena. 

Altocumulus as a whole has a very wide range of appearances, with 35 possible combinations of species and varieties. All of these clouds are mid level, made up of a bunch of small cumuliform clumps, often covering a large area.

Altostratus clouds are rarely clouds people get exited about. They come in one species and are mostly gray flat, sheets with little texture that can either dim or block out the sun entirely and make it dark outside.

Cumulus clouds are poofy and shaped like cauliflower, very easy to pick out from other clouds. They can be small or large, depending on the variety.

Stratocumulus clouds are low lying lumpy clouds that often will have patches of blue between them. There is a lot of variety in these cloud forms, with 35 listed possible combinations of species and varieties. 

Stratus clouds appear as dark and low, often as a blanket of grey. These often produce light rain and snow. They often have very little texture to them and aren't well defined.

Nimbostratus is like a stratus cloud but stretches higher into the atmosphere. Compared to stratus clouds, these are usually darker, have a slight bluish hue to them, slightly more defined and almost always accompanied with rain. 

The cumulonimbus cloud is often considered the king of clouds, being the largest of the main 10. These towering monsters go through all cloud layers, often have flat tops and you can often see it surrounded by other cloud types. These often are associated with heavy rain and lightning.
