Answer 2

The air in our atmosphere is composed of molecules of different gases. The most common gases are nitrogen (78%), oxygen (about 21%), and argon (almost 1%). Other molecules are present in the atmosphere as well, but in very small quantities.

While the composition doesn’t change much as you travel up through the lower layers of the atmosphere, what does change is the number of molecules.
