How are the top 4 gases important?
Of the gases listed, nitrogen, oxygen, water vapor, carbon dioxide, methane, nitrous oxide, and ozone are extremely important to the health of the Earth’s biosphere. Oxygen is exchanged between the atmosphere and life through the processes of photosynthesis and respiration.
What are the two most common gasses in Earth’s atmosphere?
Nitrogen and oxygen are by far the most common; dry air is composed of about 78% nitrogen (N2) and about 21% oxygen (O2). Argon, carbon dioxide (CO2), and many other gases are also present in much lower amounts; each makes up less than 1% of the atmosphere’s mixture of gases. The atmosphere also includes water vapor.
What are the two most abundant gases in the atmosphere?
Gases. The most abundant naturally occurring gas is Nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%. The inert gas Argon (Ar) is the third most abundant gas at .

What are the two most common gases in earth’s atmosphere quizlet?
What are the atmospheric gases?
Atmospheric gases are gases located in the Earth’s atmosphere. These gases primarily include oxygen and nitrogen (making up 99% of the air); though greenhouse gases (carbon dioxide, methane, nitrous oxide, water vapor and ozone) make up 1% of the air.
Which gas is rare in atmosphere?
Neon, krypton and xenon, the rare or noble gases, are only present in the air in trace amounts. Air contains just 0.0018% neon, 0.00011% krypton and 0.000009% xenon.
