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%).
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.
Earths atmosphere is dominated by which two gases?
Nitrogen and Oxygen are the two main constituents of air.

What is the makeup of earths atmosphere?
Gases
Where do these main gases come from?
they come from earths atmosphere and gases
How did volcanoes affect the early earths atmosphere?
Early volcanoes discharged different combinations of gases into the Earth's atmosphere creating rain, which cooled the planet and formed solid land masses, and every other element discovered presently.
Which gases were parts of earths original atmosphere?
HIDROGEN
How do greenhouse gases affect the earths atmosphere?
They slow the loss of heat
Two most abundant gases in earths atmosphere presently?
78% nitrogen and 21% oxygen and other gasses make up the last 1% Earth science
What are the primary gases found in earths atmosphere?
Nitrogen and oxygen,
