78% of the Earth's atmosphere is Nitrogen. Another 21% is oxygen, and the final 1% are other gases found is small amounts such as carbon dioxide, helium and methane.
Nitrogen and oxygen make up about 99% of the Earth's atmosphere. Nitrogen accounts for about 78% and oxygen for about 21%.
Earths atmosphere is rich in Oxygen, some 21% of the air is Oxygen. There is oxygen on other planets, but the percentage comes nowhere close to this. The percentage of Oxygen in earths atmosphere is thought to have been much higher in the past, before animals were about, but after the arrival of plants.
The two most abundant gases in Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%).
The 3 types of gases in Earth's atmosphere are argon, oxygen and nitrogen.
