Cheating for your homework eh?

Most abundant - Water Vapor
Co2ch4n2oo3
Water vapor was the major gas produced in the secondary (post-formation) atmosphere on Earth. Oxygen was gradually maintained as an abundant gas by the action of biological organisms.
Well, water vapor and carbon dioxide are definatley abundant in our world down here on earth and in the atmosphere. Also methane.
When magma is formed, it is composed of water vapor, carbon dioxide, and sulfur dioxide. The most abundant gas in magma is water vapor.
The water is not so abundant in the atmosphere and is very variable (o-1 %).
on ancient Earth, nitrogen, water vapor, carbon dioxide, and methane were probably the most abundant gases in the atmosphere.
Most abundant - Water Vapor
The third most abundant gas in the atmosphere is argon.
The Troposhere has the most water vapor then any other layer in the atmosphere.
The water vapor condenses.
Co2ch4n2oo3
About 78% of the atmosphere is nitrogen, while 20% is oxygen. Argon makes up less than 1%. Depending on the location, water vapor would be the third or fourth most abundant, comprising up to 4% of the atmosphere.
Troposphere. This is the lowest section of the earths atmosphere that contains 75% of the earths atmosphere by mass and 99% of the earths water vapour. This section of the atmosphere starts at the surface and extends 7-20km up, the thickness depending largely on where you are in the world.
The % of water vapor is called Humidity. The attached link will give you more information.
