which one of the following is the most abundant gas in the atmosphere course hero

Which of the following is the most abundant gas in the atmosphere *?

Nitrogen (N2)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 abundant variable gases in the atmosphere?

Water vapor and carbon dioxide are the most important of the variable gases because (1) they are the most abundant variable gases and (2) they both act as greenhouse gases, due to their ability to absorb infrared (IR) radiation, which causes the Earth's surface to be warmer than if there was no atmosphere.

What are the two most abundant gases in both the stratosphere and troposphere?

What are the two most abundant gases in Earth's atmosphere? Nitrogen and oxygen are the two most abundant gases.

Which of the following is the second most abundant gas in our atmosphere apex?

Which of the following is the second most abundant gas in our atmosphere apex? Oxygen. Oxygen is the second most abundant gas in the atmosphere and is the third most abundant element in the universe.

Why is nitrogen the most abundant gas?

Due to strong triple bond in N2(N≡N) or high activation energy, nitrogen is unreactive and thus is most abundant gas in the Earth's atmosphere.

Why is argon so abundant?

One reason is because it is non-reactive. Like other noble gases, it is stable and resists combining with other elements. Once it gets in the atmosphere it is difficult to get rid of. Another reason it is found in the atmosphere is because it is relatively heavy.

Which one of the following are the three most abundant gases in the dry atmosphere?

The most abundant gas in the atmosphere is nitrogen, second oxygen . Argon, an inert gas, is the third most abundant gas in the atmosphere.

What gas makes up most of the atmosphere?

nitrogenEarth'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.

What is the second most abundant greenhouse gas in the atmosphere?

MethaneMethane is the second most abundant anthropogenic GHG after carbon dioxide (CO2), accounting for about 20 percent of global emissions. Methane is more than 25 times as potent as carbon dioxide at trapping heat in the atmosphere.
