Question

What percent of our atmosphere is made up of gases other than oxygen and nitrogen?

Answer 1

Answer: Less than 1%

Explanation:

The atmosphere is the gaseous part of the earth. in essence, it consists of only gases. The percentage distribution of gases is as follows:

Nitrogen: 78%

Oxygen: 21%

Carbon dioxide: 0.03%

unreactive gases (argon, neon etc): Remainder

Thus, since oxygen and nitrogen account for about 99%, less than 1% is the portion shared by other gases in the atmosphere
