Two gases that probably existed in Earth's early atmosphere are what?
Two gases that probably existed in Earth's early atmosphere are ammonia and methane. These gases were likely present in significant quantities before the atmosphere transformed into its current composition.
Which gases are most abudant to earth today?
The most abundant gases in Earth's atmosphere today are nitrogen (about 78%) and oxygen (about 21%). These two gases make up the majority of our atmosphere, with other gases like argon, carbon dioxide, and water vapor present in smaller amounts.
Two main components of the atmosphere of earth?

What are the two deadly gases Four billion years ago the earth's atmosphere?
The two deadly gases present in Earth's atmosphere four billion years ago were methane and ammonia. These gases were toxic to early organisms and would have made the atmosphere hostile to life as we know it today.
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.
