What kinds of Clouds can we see ?


Clouds are made of millions of tiny water droplets or ice crystals suspended in the air. They are named according to their shape and heights.

Cirrostratus is a thin , almost transparent layer of cloud at a high level. Altostratus is a thicker layer of cloud at a higher level. Nimbostratus forms at a lower level, while stratus clouds are layers within 500 meters of the Earth's surface .'Puffy' clouds, known as cumulus clouds, are called altocumulus at a high level. When they join together they form stratocumulus.
Cumulonimbus are towering thunder clouds. A third type of cloud is cirrus, wisps of clouds high in the sky.
