Nearly all of the Earth's atmosphere is made up of only five gases: nitrogen, oxygen, water vapor, argon, and carbon dioxide.Several other compounds are also present. Although this CRC table does not list water vapor, air can contain as much as 5% water vapor, more commonly ranging from 1-3%.The 1-5% range places water vapor as the third most common gas (which alters the other percentages ...

Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements. Our atmosphere also contains water vapor. In addition, Earth's atmosphere contains traces of dust particles, pollen, plant grains and other solid particles.

The stratosphere is a layer of the atmosphere that consists of nearly 19 percent of the atmosphere's gases, which are nitrogen, oxygen, argon and trace elements like neon and helium. The atmosphere consists of five layers, and its gas composition is 78 percent nitrogen, 21 percent oxygen and 0.9 percent argon.

Fifty percent of the total mass of the atmosphere is located in the lower 5.6 km (3.5 mi; 18,000 ft) of the troposphere. Nearly all atmospheric water vapor or moisture is found in the troposphere, so it is the layer where most of Earth's weather takes place.
