Which gas makes up the majority of the atmosphere?
The answer is: nitrogen.
The majority of Earth's atmosphere is made up of a group of gases, the most prominent of which is nitrogen.
Nitrogen makes up about 78% of the atmosphere, as well as about 21% oxygen, 0.9% argon, and 0.032% carbon dioxide.
These gases are essential to life on Earth and play an important role in regulating climate and weather patterns.
In addition, trace amounts of water vapor and other gases such as methane, nitrous oxide, and ozone are also present in the atmosphere.
Collectively, these gases form a protective layer that helps keep Earth's surface warm enough to sustain life.
