The earths atmosphere is dominated by which two gases?
Nitrogen (N2) - 78% Oxygen (O2) - 21%
What two gases is the earths atmosphere dominated by?
Nitrogen and oxygen, respectively, are the two most abundant gases in the earth's atmosphere.
What two gases probably dominated Precambrian Earths atmosphere?
The two gases that probably dominated Earth's atmosphere during the Precambrian era were carbon dioxide (CO2) and nitrogen (N2). These gases were likely present in much higher concentrations than oxygen.
Earth's atmosphere presently dominated by which two gases?
If i remember right it should by nitrogen and oxygen :)
What are the two most abundant gases in earths atmosphere presently?
The two most abundant gases in Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%).

What two gases make up approximately 99 of earths atmosphere?
Nitrogen and Oxygen.
What is earths atmosphere two gases?
Nitrogen and oxygen make up the majority of the atmosphere, but there are other gases as well, such as carbon dioxide, ozone, and helium.
What are the two gases that existed in earths earlier atmosphere?
The original atmosphere of earth contained primarily ammonia and methane, very similar to the atmosphere on Venus and Jupiter today.
What are the two most abundant gases which make up the earths atmosphere?
Nitrogen N2 78.08% Oxygen O2 20.95%
Two most abundant gases in earths atmosphere presently?
78% nitrogen and 21% oxygen and other gasses make up the last 1% Earth science
Why do the properties of the two gases in the atmosphere does not change?
There are more than two gases in the atmosphere. You need to specify the ones you are asking about.
Which two gases in Earths atmosphere are believed by scientists to be greenhouse gases that are major contributors to global warming?
When we speak of global warming, we usually mean the recent increase in average global temperatures. The two gases considered to be the major contributors to this effect are carbon dioxide and methane.
