Oxygen is by far the more plentiful. There is about 21% of oxygen in fresh air, but only 0.04 % of carbon dioxide.
carbon dioxide
This gas is oxygen.
Carbon dioxide (CO2) gas rises in the atmosphere.
Carbon dioxide
The atmosphere is about 78% nitrogen. Next is oxygen at around 21%.
Carbon dioxide (CO2) is the main gas produced by human activity that is causing the atmosphere to grow warmer.
Nitrogen, approx. 80 %.
Nitrogen, approx. 80 %.
Water vapor is a more potent greenhouse gas than carbon dioxide (CO2) in the Earth's atmosphere. While CO2 is more abundant, water vapor has a stronger warming effect due to its ability to trap heat.
No Nitrogen is
There would be more carbon dioxide (CO2) in the atmosphere. Carbon dioxide is a greenhouse gas, so more heat would be captured in the atmosphere and global warming would increase.
CO2, H2O, methane.
