What is the most important gas in atmosphere?
Not only does it contain the oxygen we need to live, but it also protects us from harmful ultraviolet solar radiation. It creates the pressure without which liquid water couldn’t exist on our planet’s surface. And it warms our planet and keeps temperatures habitable for our living Earth.

What are the minor gases?
2.2 The Minor (Trace) Constituents of the Atmosphere. The remaining 0.1% of the atmosphere consists of the trace constituents. These include water vapor, carbon dioxide, ozone, methane, various oxides of nitrogen, neon, and helium. They are called trace gases because they exist in small amounts.
