Carbon dioxide in 2014 made up 0.04% of the atmosphere. This figure is rising every year.
Argon is the unreactive gas that makes up 1 percent of the Earth's atmosphere. It is a noble gas and is commonly used in applications where an inert atmosphere is required, such as in light bulbs and welding.
Nitrogen (N2) is the most abundant gas in the Earth's atmosphere having percent volume of 78.8 compare to Oxygen 20.95 %, which falls on the second place after Nitrogen.
Nitrogen makes up approximately 78% of the Earth's atmosphere by volume. This makes it the most abundant gas in the atmosphere, followed by oxygen, which constitutes about 21%. The remaining 1% includes argon, carbon dioxide, and other trace gases.
The dominant atmospheric gases on Mercury are oxygen, sodium, hydrogen, helium, and potassium. However, the atmosphere on Mercury is very thin, with a pressure about 10^-15 times that of Earth's atmosphere.
Approximately 20 percent of the Earth's atmosphere is made up of oxygen.
Oxygen is the gas that makes up about 21 percent of the Earth's atmosphere.
Carbon dioxide (CO2) is the gas that makes up 0.036 percent of Earth's atmosphere.
Oxygen is the gas that accounts for about 20 percent of Earth's atmosphere.
Oxygen makes up 21 percent of Earth's atmosphere.
