WebbA majority portion of the atmosphere is composed of two gases: nitrogen and oxygen. Carbon dioxide, helium, ozone, argon, and hydrogen are all present in smaller quantities. Besides these gases, there are also small dust particles in the air. Fig.1: Composition of Air 2.1. Nitrogen Nitrogen is present in the largest amount in the atmosphere. Webb7 mars 2024 · We breathe oxygen and plants take CO 2 from us for photosynthesis. But besides these two gases, there are several other components that create our atmosphere. However, only two gases create the bulk of the atmosphere as they are present about 99% and the rest of the different gases are present about only 1%.
