Answer:

Earth's atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.

Answer 2

Explanation:

Earth's atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. Trace amounts of carbon dioxide, methane, water vapor, and neon are some of the other gases that make up the remaining 0.1 percent.

Nitrogen and oxygen together make up 99% of the planet's atmosphere. The rest of the gases are minor components but sometimes are very important (Figure below). Nitrogen and oxygen make up 99% of the atmosphere; carbon dioxide is a very important minor component. Humidity is the amount of water vapor in the air.
