This table lists the eleven most abundant gases in the lower portion of Earth's atmosphere (up to 25 km). While the percentage of nitrogen and oxygen are fairly stable, the amount of greenhouse gases changes and depends on location. Water vapor is extremely variable. In arid or extremely cold regions, water vapor may be nearly absent. In warm, trop...
It's important to know which gas is most abundant, what the other gases are in the Earth's atmosphere, and how the composition of air changes with altitude and over time for multiple reasons. The information helps us understand and predict the weather. The amount of water vapor in the air is particularly relevant to weather forecasting. The gas com...

- Nitrogen (78.1%) While nitrogen is the most abundant gas in Earth’s atmosphere, it only makes up 0.005% of Earth’s crust in weight (David Darling). Nitrogen is incredibly stable and requires a lot of energy to change forms.
- Oxygen (20.9%) Earth has the conditions for life to flourish. Oxygen is essential to human life as our lungs respire oxygen and uses it in metabolism.
- Argon (0.93%) As an inert gas, argon doesn’t bond or do much in the atmosphere. This is why there’s no argon cycle. But we have nitrogen and carbon because of their ability to bond with other elements.
- Carbon Dioxide (0.04%) Carbon is the most important element for building molecules essential for living things. As you can see from the long-term carbon cycle, carbon takes up various forms such as carbon dioxide (CO2), methane (CH4), and glucose (C6H12O6).
Jun 25, 2024 · The atmosphere’s most abundant greenhouse gases are carbon dioxide, water vapor, and methane. Fast-moving, high-altitude winds called jet streams swirl around the planet near the upper boundary of the troposphere.
Jun 14, 2019 · The most abundant gas in the atmosphere is nitrogen. The Earth’s atmosphere is composed of approximately 78 percent nitrogen, 21 percent oxygen, 1 percent argon and trace amounts of other gases that include carbon dioxide and neon.

Gases in the Air. The most abundant naturally occurring gas is nitrogen (N 2), which makes up about 78% of air. Oxygen (O 2) is the second most abundant gas at about 21%. The inert gas argon (Ar) is the third most abundant gas at 0.93%.
Nitrogen and oxygen are by far the most common gases in our atmosphere. Dry air is composed of about 78% nitrogen (N 2) and about 21% oxygen (O 2). The remaining less than 1% of the atmosphere is a mixture of gases, including argon (Ar) and carbon dioxide (CO 2).
