Nitrogen.
nitrogen
At reasonable temperature nitrogen is a gas. Most of the air is nitrogen.
Not a lot, most volcanoes have solidified on the surface so there is no open lava at the surface. It would be pouring liquid nitrogen onto rock which would not do much at all. Even if there were some lava on the surface pouring liquid nitrogen onto it would just accelerate the cooling and solidifying into rocks dependent on what type of lava it is.
It is nitrogen, followed by oxygen.
it is the part of the nitrogen cycle
Bacteria is the organism most critical in the nitrogen cycle. Bacteria in the nitrogen cycle provides different forms of nitrogen compounds used by higher organisms.
