gases, primarily nitrogen and oxygen
Carbon dioxide makes up 95% of Mars' atmosphere.
oxygen,nitrogen,helium,hydrogen
that would be oxygen and nitrogen
Im pretty sure its oxygen and nytrogen
It comes from the process of planetary differentiation. light elements such as nitrogen rise up to form the atmosphere,whereas heavy elements such as iron sink to the mantle.
The Moon has no atmosphere.
nirtrogen
Hydrogen and Helium
Carbon dioxide makes up 95% of Mars' atmosphere.
nitrogen and oxygen
Hydrogen and Helium
carbon dioxide and nitrogen are 2.
Two elements,Nitrogen and Carbon Dioxide.Almost 99%
oxygen,nitrogen,helium,hydrogen
Not all of the elements are present in the Earth's atmosphere.
99% of the atmosphere is nitrogen (78%) and oxygen (21%).
that would be oxygen and nitrogen
