Nitrogen, oxygen and argon are called the "constant gases" because their concentration has remained virtually the same for much of recent earth history.Nitrogen (78%)is a relatively inert gas produced primarily by volcanic activity. It is an important component of protein in meat, milk, eggs and the tissues of plants, especially grains and members of the pea family. It cannot be ingested directly by organisms but made available to plants, and then to animals, by compounds in the soil. Most atmospheric nitrogen enters the soil by nitrogen-fixing microorganisms.
Oxygen (21%) is important for plant and animal respiratory processes. It is also important to chemical reactions (oxidation) that breakdown rock materials (chemical weathering). Without oxygen, things cannot burn either. Free oxygen in the atmosphere is a product of plant photosynthesis. Plants take up carbon dioxide and in the process of photosynthesis release oxygen.
Argon (.93%) is a colorless, odorless relatively inert gas, the reason it use to electric light bulbs, fluorescent tubes. It is used to form inert atmosphere for arc welding, and growing semiconductor crystals.
The three most abundant gases in Earth's atmosphere are nitrogen (78%), oxygen (21%), and argon (0.93%).
The three most common gases in the dry atmosphere are nitrogen (78%), oxygen (21%), and argon (0.93%).
The three most common gases in Earth's atmosphere are nitrogen (N2), oxygen (O2), and argon (Ar). Nitrogen makes up about 78% of the atmosphere, oxygen comprises about 21%, and argon is present at about 0.93%.
The 3 types of gases in Earth's atmosphere are argon, oxygen and nitrogen.
The atmosphere is primarily composed of nitrogen (78%), oxygen (21%), and argon (less than 1%). These three gases together make up the bulk of Earth's atmosphere, but there are also trace amounts of other gases like carbon dioxide, water vapor, and methane.
Three gases in the atmosphere are nitrogen, oxygen, and carbon dioxide.
The three main gases in Earth's atmosphere are nitrogen, oxygen, and argon. Nitrogen makes up about 78% of the atmosphere, oxygen about 21%, and argon about 0.93%.
Three of the gases in Mars' atmosphere are carbon dioxide, nitrogen, and argon. Carbon dioxide makes up the majority of the atmosphere, followed by nitrogen and then argon.

The three most common gases in Earth's atmosphere are nitrogen (N2), oxygen (O2), and argon (Ar). Nitrogen makes up about 78% of the atmosphere, oxygen comprises about 21%, and argon is present at about 0.93%.
The 3 types of gases in Earth's atmosphere are argon, oxygen and nitrogen.
The three major gases in Earth's atmosphere are nitrogen (around 78%), oxygen (around 21%), and argon (around 0.9%). These gases play crucial roles in supporting life and regulating the Earth's climate.
These gases are: nitrogen (78,084 %), oxygen (20,9476 %), argon (0,934 %), carbon dioxide (0,0314).
The three most common gasses in our atmosphere are: nitrogen 78%, oxygen 21%, and argon <1%.
The atmosphere is primarily composed of nitrogen (78%), oxygen (21%), and argon (less than 1%). These three gases together make up the bulk of Earth's atmosphere, but there are also trace amounts of other gases like carbon dioxide, water vapor, and methane.
There are various gases that are released into the atmosphere. Carbon dioxide, methane, and nitrous oxide are three of them.
