No. Most of the atmosphere (regardless of the up to 1% water in the lower troposphere) is composed of nitrogen. Wikipedia lists the average composition of dry atmosphere, by volume, as follows:
Nitrogen, N2 78.084% Oxygen, O2 20.946% Argon, Ar 0.934%

Is most of earth' s atmosphere oxygen?
Most of the oxygen is in the troposphere. Stratosphere contains ozone. It is the converted oxygen.
Why does the stratosphere have less oxygen than the troposphere?
We know that oxygen is just a bit heavier than the air like carbon dioxide ,nitrogen etc.Besides that the main source of oxygen,the trees is in troposphere. Because of this reasons oxygen density is much heavier in troposphere than the stratosphere
How does the troposphere affect life on earth?
The troposphere is where most life on earth lives. It is where we have our air and makes our weather.
What is the difference between troposphere and the thermoshpere?
The difference between the troposphere and the thermosphere is the troposphere is the second layer of the atmosphere where all of the birds hot air balloons and airplanes fly. The Thermosphere is the third layer of the atmosphere where their is less oxygen.
Most of Earths dry air is made up of whAT?
nitrogen and oxygen

What is the layer of the earth which is a form of oxygen and filters out most of the sun UV's radiation?
The oxygen is mostly found in the troposphere. However most of the oxygen formed OZONE is found in stratosphere. It is due to the pressure of air there and the UV rays.
How is oxygen in air replaced?
As the third most abundant element, oxygen in the air is made by plants and algae.
Most of the air you breathe is made up of?
Oxygen
Which layer of the atmosphere has the most air?
Troposphere
How does the troposphere affect life on earth?
The troposphere is where most life on earth lives. It is where we have our air and makes our weather.
Which layer would have the most air pollution on the atmosphere?
The troposphere

Most of Earths dry air is made up of whAT?
nitrogen and oxygen
Am air made of oxygen?
About 20% am. Most of it's nitrogen, though.
Where is air greater in the exosphere or in the troposphere?
troposphere
