The document discusses the four basic cloud types: cirrus, stratus, cumulus, and nimbus. Cirrus clouds are thin and wispy, while stratus clouds are flat and close to the ground. Cumulus clouds are puffy and can develop towers bringing thunderstorms. Nimbus clouds produce rain. The clouds are further classified by height into high, middle, and low-level clouds. Common cloud types are described along with different forms of precipitation.
