The next most abundant gas is (3) water vapor. Water vapor varies in concentration in the atmosphere both spatially and temporally. The highest concentrations of water vapor are found near the equator over the oceans and tropical rain forests.
The most abundant gases found in our atmosphere are nitrogen and oxygen. Nitrogen makes up around 78% of the total atmosphere, while oxygen makes up 21%. The remaining 1% is made up mostly of a gas called argon.xygen is the most important of the gases in our atmosphere in relation to animal life.
