Types of Cloud

Today I'm going to talk about types of cloud. Cloud is made by water molecules and there is lots of types of clouds. Scientists classify the cloud based on height of cloud. There is 3 kinds of cloud. First one is high-level clouds. They form above 20,000feet and usually because of cold weather, water molecules freezes and formed a cloud. Second type of cloud is mid-level cloud. Mid-level clouds form between 6,500 ft to 20,000 feet. Because of their low altitude, a lot of mid-level clouds become the rain. If weather is cold enough, they can be changed in ice crystals and make snows. Last type of cloud is low-level clouds. Low-level clouds lie below 6,500 feet and it is the primary reason of raining. Also, if weather is cold enough to freeze them, it can be ice crystals and make snow also.
