These gases are nitrogen and oxygen.
These gases are nitrogen and oxygen.
The second most abundant gas in the Earth's atmosphere is oxygen, which makes up about 21% of the gases in the atmosphere.
The Abundant gases are Nitrogen, Helium, and other gases in the Secondary Atmosphere.
The most abundant gases are nitrogen and oxygen in the Earth atmosphere.
Nitrogen is the most abundant gas in Earth's atmosphere, followed by oxygen, argon, and carbon dioxide.
Helium is the most abundant of the Noble gases in the universe.
The Earth atmosphere is formed from gases.
These gases are hydrogen and helium.
The two most abundant gases in Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%).
The most abundant gas in Earth's first atmosphere was likely hydrogen gas (H2), along with smaller amounts of helium and trace gases like methane and ammonia. Over time, these gases were modified as a result of volcanic activity and the emergence of life forms on Earth.
Nitrogen leads the way, with Oxygen running second. The rest are not "abundant", but on a humid day water vapor can get up to 4 or 5 percent.
