The primary gas in Earth's atmosphere is nitrogen, accounting for about 78% of the total atmospheric composition.
Helium is not one of the primary gases found in Earth's atmosphere. The primary gases in Earth's atmosphere are nitrogen, oxygen, argon, and carbon dioxide. Helium makes up a very small percentage of the atmosphere.
Volcanic activity was the primary source of CO2 in the Earth's early atmosphere. During this time, volcanic eruptions released large amounts of gases, including carbon dioxide, into the atmosphere.
The primary gas found in Earth's atmosphere is nitrogen, making up about 78% of the air we breathe. Oxygen is the second most abundant gas, making up about 21% of the atmosphere.
