What is the third most abundant gas in the earth's atmosphere?

Answer 1

Argon: "It contains roughly (by molar content/volume) 78% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide,"

Answer 2

The third most abundant gas in the earth's atmosphere is a rare gas 'argon' (which constitutes 0.9% of the air).

Answer 3

The thin envelope of air that surrounds our planet is a mixture of gases, each with its own physical properties. The mixture is far from evenly divided. Two elements, nitrogen and oxygen, make up 99% of the volume of air.

!!____The other 1% is composed of "trace" gases, the most prevalent of which is the inert gaseous element argon.____!!

The rest of the trace gases, although present in only minute amounts, are very important to life on earth. Two in particular, carbon dioxide and ozone, can have a large impact on atmospheric processes.

Answer 4

Nitrogen 78.084%
Oxygen 20.946%
Argon 0.9340%
Carbon dioxide 0.0383%
Neon 0.001818%
Helium 0.000524%
Methane 0.0001745%
Krypton 0.000114
Hydrogen 0.000055%
Water vapor- .25% overall, typically 1-4% closer to surface

theres even a tiny amount of nitrous oxide (yes, laughing gas), Xenon, Carbon Monoxide, methane and ammonia

Answer 5

The third most abundant gas element is argon at 0.93% but there is about 1% water vapor.

Answer 6

ARGON ( amout 1% vol.)
Argon in an inert gas from the family of
He, Ne, A, Kr, Xr, Rn

Answer 7

In absolutely dry air it is argon at 0.93 % of the volume. In very humid air it is watervapour but the amount of watervapour vaires greatly while the level of argon is pretty much constant.

Answer 8

There is 78% Nitrogen, 20.95% Oxygen, .93% argon, and .83% carbon dioxide. So i think it is argon but people fight over it and water vapor. hope this helps! :)

Answer 9

Most people say argon. But water vapor puts up a good fight.

Answer 10

Argon (~1%).
