Detailed explanation-1: -Oxygen is the most abundant element in the Earth’s crust. Since oxygen is reactive elements and forms compounds with most of the other elements hence it is found in abundance.
Detailed explanation-2: -#1: Oxygen Oxygen is by far the most abundant element in the Earth’s crust, making up 46% of mass-coming up just short of half of the total. Oxygen is a highly reactive element that combines with other elements, forming oxides.
Detailed explanation-3: -Nitrogen is the seventh most abundant element in the universe and is a major constituent of the atmosphere on Titan, the largest of Saturn’s 62 moons.
Detailed explanation-4: -Oxygen is a major component of the solid earth, along with Si and elements such as Mg, Ca and Na. Nitrogen is not stable as a part of a crystal lattice, so it is not incorporated into the solid Earth. This is one reason why nitrogen is so enriched in the atmosphere relative to oxygen.
