Answer the following question given this paragraph: A: Air in the atmosphere is a gaseous solution. It is a mixture that contains mainly nitrogen and oxygen gases, with very small amounts of several other gases. The circle graph in the Figure below shows the composition of air. Because air is a solution, it is homogeneous. In other words, no matter where you go, the air always contains the same proportion of gases that are shown in the graph. Q: Which two gases make up the bulk of earth's atmosphere? Choices: - carbon and oxygen - phosphorus and oxygen - nitrogen and argon - nitrogen and oxygen A:
(A).
nitrogen and oxygen
