The primary gases in Earth's primitive atmosphere were likely hydrogen, helium, methane, ammonia, and water vapor. Over time, these gases were likely transformed by geological and biological processes into the current composition of the atmosphere.
Nitrogen is the largest component of Earth's present atmosphere, making up about 78% of the total gases in the atmosphere.
Oxygen was lacking in the atmosphere of primitive Earth. Instead, the atmosphere was primarily composed of gases such as carbon dioxide, nitrogen, methane, ammonia, and water vapor.
The primary gas in Earth's atmosphere is nitrogen, accounting for about 78% of the total atmospheric composition.
Oxygen is the gas that accounts for about 20 percent of Earth's atmosphere.
Nitrogen makes up about 78% of Earth's atmosphere.
Nitrogen is about 79% of the Earth's atmosphere.
Nitrogen is the largest component of Earth's present atmosphere, making up about 78% of the total gases in the atmosphere.
Nitrogen is the most abundant gas but the interesting thing about it, is that we can not use it in the gaseous state.
Ozone gas is present as ozone layer. It absorbs the UV rays of the sun.
