Water undergo a long journey at it's cycle. One of the process in water cycle is water evaporation which transform water's form from liquid into gas. This water then evaporate and go to troposphere layer (one of the atmosphere layer) and form cloud there. This cloud is divided into 3 kind of clouds based on it's height, "Low Clouds, Medium Clouds, High Clouds". This cloud is also has it's own name and it's own form.

The lowest cloud is "Stratus". This cloud usually formed at morning until day time. This cloud has a layered shape. This cloud isn't cause rain. Higher than this cloud, there's "Stratocumulus".

On the higher height, there's "Cumulus", a cloud that shaped like a thick cloud. This cloud usually formed at afternoon and potentially cause rain. Especially if this cloud accumulated and formed "Cumulonimbus", a giant rain cloud.

Higher than Cumulus are clouds which classified as "Medium Clouds" the example of medium clouds are "Altocumulus, Altostratus, etc. These clouds classified as medium clouds because their height that reach more than 2000 meters from Earth surface. Most of them have a clod shaped.

The rest of the clouds are classified as "High Clouds". These clouds height usually more than 7000 meters above earth. "Cirrocumulus and Cirrus are the example of High Clouds.

The largest cloud is "Cumulonimbus". Amazingly, this cloud stands from 1000 meters above earth surface (the height of the lowest cloud) and reach around 7600 meters height from earth. This cloud usully cause heavy rain, thunderstorm, tornado, and tropic cyclone. That's why this "Gray-Clotted Clouds" called "Rain cloud".9xujrw46da
