Atmosphere: Role, Structure & Composition | PMF IAStmosphere, then the dry air is very stable all over the earth up to an altitude of about 80 kilometres. The proportion of gases changes in the higher layers of the atmosphere in such a way that <span>oxygen will be almost in negligible quantity at the height of 120 km. Similarly, carbon dioxide and water vapour are found only up to 90 km from the surface of the earth. Nitrogen and oxygen make up nearly 99% of the clean, dry air. The remaining gases ar Summary
