What elements make up the earth's atmosphere?

Answer 1

Nitrogen gas, oxygen gas, argon, carbondioxide, etc.

The makeup of pure, dry air is

Nitrogen (#N_2#) 78.08%; oxygen (#O_2#) 20.95%; argon (Ar) 0.93%; carbondioxide (#CO_2#) 0.04%; neon (Ne) 0.0018%; helium (He) 0.0005%), etc.

Because of the continuous increase in greenhouse gas emissions and the decline in photosynthetic plants, natural areas, etc., carbon dioxide levels have been rising noticeably.
