Carbon, Oxygen, Nitrogen, Hydrogen

The two main gases are Nitrogen (N2) and Oxygen (O2), which comprise around 78% and 21% of the atmosphere by volume respectively. The remaining 1% is mostly Argon (Ar), followed by Carbon Dioxide (CO2) as well as several other gases present in trace amounts. All of these figures are for dry air, however water vapour (H2O) is also present in air at levels of up to 4%, but this is highly variable depending on localised conditions, and it makes up a lower percentage of the atmosphere as a whole.
Sorry, but your data is wrong. Nitrogen does reach the surface. Its 4/5 th of the atmosphere.
Because those are 4 of the most abundant (or most reccuring) gases in Earth's atmosphere.
The atmosphere protects us tons of ways but here are most important ones. 1) It protects from sun rays because we would all be dead right now. 2) It helps airplanes because the Troposphere (the layer we are in) is the only layer that has weather so airplanes go up higher to the Stratosphere (layer on top of us) 3)It burns up asteroids before they touch down to Earth. 4) It lets us breath!!!!!!!!!!!!!!
78% nitrogen, 21% oxygen, 1% carbon dioxide and other minute gases
argon
Nitrogen and oxygen together make up about 99% of the atmosphere by volume. Most of the remaining 1% is argon. Under humid conditions water vapor may make up 2-4% of the air.

There are not a lot of noble gases that are in the atmosphere. It is estimated that about 2 percent of the atmosphere contains them.
Their are 4 ways that gases enter the ocean. Gases can enter the ocean from streams, volcanoes, organisms, and the atmosphere.

biosphere ,hydrosphere ,atmosphere ,lithosphere are the four spheres of the earth
carbon monoxide, oxygen, nitrogen, carbon dioxide
It was about 4 billion years ago, that the Earths oceans formed
Nitrogen, Oxygen, Carbon Dioxide, and Water Vapor
You must be thinking of water. It varies a lot, but can be up to about 4%.
