What kind of gas is most of the atmosphere made of?

Answer 1

The Earth's atmosphere is composed of the following molecules: nitrogen (78%), oxygen (21%), argon (1%), and then trace amounts of carbon dioxide, neon, helium, methane, krypton, hydrogen, nitrous oxide, xenon, ozone, iodine, carbon monoxide, and ammonia. Lower altitudes also have quantities of water vapor.

The earth's atmosphere is made up of:

• Nitrogen (N2) 78.084%
• Oxygen (O2) 20.946%
• Argon (Ar) 0.934%
• Carbon dioxide (CO2) 0.0400%
• Neon (Ne) 0.001818 %
• Helium (He) 0.000524 %
• Methane (CH4) 0.0001745 %
• Krypton (Kr) 0.000114%
• Hydrogen (H2) 0.000055 %

There is also a varying amount of water vapor, depending on the altitude and conditions where it is measured.
The most common gases in Earth's atmosphere are nitrogen, oxygen, and some argon. Nitrogen makes up about 78% and oxygen about 21%, with argon making up less than 1%.

There are a few other gases present in very small amounts, including carbon dioxide, ozone, and methane. These can have significant effects even in very small concentrations.

Water vapour is present in Earth's atmosphere, sometimes in large quantities, but it is not included above because it is a vapour, not a gas. That is, it is capable of condensing to a liquid or solid at the normal temperatures of Earth's atmosphere, and "rains out".

Answer 2

The Earth's atmosphere consists of mainly these gases:

1. Nitrogen- 78%
2. Oxygen- 21%
3. Argon-1%
4. Carbon Dioxide- less than 1%

There are also several other gases present, in even smaller amounts.

Answer 3

The atmosphere of Earth is conducive to supporting life. The atmosphere is made up of 78.08% nitrogen, 20.95% oxygen, 0.930% argon, 0.039% carbon dioxide, and about 1% water vapor depending on the climate. This means that a climate that is more humid will likely have more water vapor in the air than a climate that is arid and dry.

Answer 4

Probably carbon-dioxide and sulfur compounds from volcanoes.

Hydrogen and Helium

A

nswer:

Depends how far you go back:

• First Atmosphere: Probably H2, He
• Second Atmosphere from volcanic out gassing: Based on modern volcanic gases - H2O, CO2, SO2, CO, S2, Cl2, N2, H2) and NH3 (ammonia) and CH4 (methane)
• Present atmosphere: 78% Nitrogen, 21% Oxygen, 1% Argon and traces of other gases

Answer 5

The Earth's atmosphere is about 79% nitrogen, 20% oxygen, and 1% "other" gasses. The "Other" includes water vapor (H2O), carbon dioxide (CO2), various nitrogen oxides (NOX, where "x" can be 2, 3 or 4), "noble" gasses such as argon, neon, or helium, or organic gasses such as methane.

Answer 6

Earth is surrounded by an atmosphere of gases and contains mostly nitrogen (78%) and oxygen (21%) with traces of argon, carbon dioxide, and water.

Answer 7

78% nitrogen

21% oxygen

1% other gases like argon, carbon dioxide etc.

Answer 8

The Earth's atmosphere is 79% nitrogen, 20% oxygen, and 1% other stuff. The "other" includes carbon dioxide, carbon monoxide, methane, hydrogen, helium, neon, radon, and all the other gases.

Answer 9

Most of the earth's atmosphere ... about 78% ... is nitrogen.

Answer 10

The earth's atmosphere is made up OS fuzzy puppys. They all are black incase you are wondering.
