This is a rare cloud that only forms and keeps its shape for only six minutes. It is called a Cirrus cloud.
This cloud is a Manmatus cloud, it is usually left after a very severe storm.
This is a Nacreous cloud, it most often shows up in northern areas of the world, but not exclusively.
This is a mushroom cloud, they show up only from very large explosions, such as nuclear bombs, or volcanoes.
This is a roll cloud, they form from jet streams in the air and then when they exit the jet stream this is the result.
This is a shelf cloud, which is similar to a roll cloud, only it is being blown by the wind sideways into a much larger looking shape.
That was all for now, but I will be coming up with new articles soon, please comment! I hope you enjoyed my knowledge.
