What makes up are air?

Standard Dry Air is made up of nitrogen, oxygen, argon, carbon dioxide, neon, helium, krypton, hydrogen, and xenon. It does not include water vapor because the amount of vapor changes based on humidity and temperature. Nitrogen and oxygen make up about 99 percent of Earth’s air.

What 5 elements make up the air?

According to NASA, the gases in Earth’s atmosphere include:

• Nitrogen — 78 percent.
• Oxygen — 21 percent.
• Argon — 0.93 percent.
• Carbon dioxide — 0.04 percent.
• Trace amounts of neon, helium, methane, krypton and hydrogen, as well as water vapor.

How do you explain air to a child?

Air is a tasteless, odorless and invisible mix of gases that is primarily made up of oxygen and nitrogen. There are layers of air that cover the earth, which is known as the atmosphere. All over the world, there are large and small bodies of air called air masses that remain about the same temperature and moisture.

What 3 things make up air?

The molecules of two different elements, nitrogen and oxygen, make up about 99 percent of the air. The rest includes small amounts of argon and carbon dioxide. (Other gases such as neon, helium, and methane are present in trace amounts.) Oxygen is the life-giving element in the air.

What kind of stuff is in the air?

Air also contains dust, pollen, spores, bacteria, and other bits of solid and liquid matter. Air can be greatly compressed. All the air in a space as big as a house can be squeezed into a small tank. On the other hand, air can expand almost indefinitely.

Which is the most common element in air?

In air the most common of these elements are nitrogen and oxygen. Oxygen is an important component of air because humans and other animals need it to survive. In addition to nitrogen and oxygen, air consists of small amounts of the gases argon, neon, helium, and methane. Besides gases, air also contains water vapor, dust, pollen, and bacteria.

What makes up 99 percent of the air?

The molecules of two different elements, nitrogen and oxygen, make up about 99 percent of the air. The rest includes small amounts of argon and carbon dioxide. (Other gases such as neon, helium, and methane are present in trace amounts.) Oxygen is the life-giving element in the air.

What makes up the air in the Earths atmosphere?

It’s a mixture of different gases. The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen. Air also has small amounts of lots of other gases, too, such as carbon dioxide, neon, and hydrogen. 1 of 11
