By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.
Likewise, what gases are in the layers of the atmosphere?
According to NASA, the gases in Earth's atmosphere include:
- Nitrogen — 78 percent.
- Oxygen — 21 percent.
- Argon — 0.93 percent.
- Carbon dioxide — 0.04 percent.
- Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor.
What are the gases in the troposphere?
Most prevalent gases are nitrogen (78 percent) and oxygen (21 percent), with the remaining 1- percent consisting of argon, (.9 percent) and traces of hydrogen ozone ( a form of oxygen), and other constituents. Temperature and water vapor content in the troposphere decrease rapidly with altitude.
What are the gases found in the mesosphere?
The gases in Earth's atmosphere include:
- Nitrogen – 78 percent.
- Oxygen – 21 percent.
- Argon – 0.93 percent.
- Carbon dioxide – 0.038 percent.
