Volcanic degassing   ---  Carbon Dioxide.Comets and meteoroids  --  Icy debris.Condensation of water vapour.   --  rain.

Explanation:

A volcanic degassing represents the essential components of the global geochemical cycles. As volcanic gases are composed fo the carbon and other primordial gases and also have constituted the earth mantle and the atmosphere. Comets and the meteoroids are a small piece of rocks that are broken off the comets and consist of the debris forms and thus are pulled by the gravity of the earth, as they are bodies if ice, dust, and rocks. The roan drips are a result of the condensation of the water vapor s that result from the condensation of the water in high altitudes in the cloud layers.
