The droplets or particles are suspended in the atmosphere above the surface of a planetary body. On Earth, clouds are formed by the saturation of air in the homosphere (which includes the troposphere, stratosphere, and mesosphere).

Nephology is the science of clouds which is undertaken in the cloud physics branch of meteorology.
