The most abundant element in Earth's atmosphere is nitrogen, making up about 78% of the air we breathe. Oxygen is the second most abundant element in the air, at around 21%.
Oxygen is the second most abundant element by volume in both the Earth's crust (after silicon) and in the Earth's atmosphere (after nitrogen).
The two Earth regions where oxygen is the second most abundant element by volume are the Earth's crust, after silicon, and the Earth's atmosphere, after nitrogen.
