The original atmosphere of earth contained primarily ammonia and methane, very similar to the atmosphere on Venus and Jupiter today.
Gases
they come from earths atmosphere and gases
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.
HIDROGEN
They slow the loss of heat
Nitrogen and oxygen,
the entire atmosphere...
Nitrogen & oxygen.
These gases are nitrogen, oxygen, argon, carbon dioxide.
Hydrogen and helium
Nitrogen, Oxygen and Argon make up 99% of the atmosphere
The two most abundant gases in Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%).
