What are the main 4 gases in the atmosphere?

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.

What are the four gases?

I call them the four deadly gases – carbon dioxide, methane, nitrogen oxides, and F-gases – which are driving global climate change through the greenhouse effect . Each gas has a different warming effect.

What are the four main gases that make up the atmosphere?

Home Science Earth Science Atmosphere. The four main gases in the atmosphere are nitrogen, oxygen, argon and carbon dioxide. However, two of these gases make up most of the atmosphere. They are nitrogen and oxygen, which between them account for over 99 percent of the atmosphere. Nitrogen is the most common gas.

What makes up 99 percent of the atmosphere?

However, two of these gases make up most of the atmosphere. They are nitrogen and oxygen, which between them account for over 99 percent of the atmosphere.

Which is the smallest gas in the atmosphere?

Other gases that can be found in even smaller amounts include water vapor, methane, sulfur dioxide, ozone and nitrogen oxides. Apart from water vapor, these gases only contain trace elements. Water vapor varies from trace elements up to as much as 0.4 percent.

Why are some gases more abundant than others in the atmosphere?

Warm air holds more water than cool air. On a much smaller scale, near the surface forests, the amount of oxygen and carbon dioxide can vary slightly from day to night. While the atmosphere near the surface has a fairly homogeneous chemical composition, the abundance of gases changes at higher altitudes. The lower level is called the homosphere.
