Additionally, varieties of clouds are discussed according to their arrangement and transparency. There is a classification of heights called high, medium and low altitudes. The different types of clouds are found in these three divisions depending on the altitude of the clouds. First, we have the high clouds which range in altitude from 16,500 to 45,000 feet. In this division we have cirrus clouds, cirrocumulus clouds and cirrostratus clouds. A cirrus cloud appears as delicate, feather-like bands that are not attached to each other and are usually white without shadow. Cirrocumulus clouds look like very small round balls or flakes.
