The density of the atmosphere varies with height. It is the highest at sea level. It decreases rapidly with increase in height. Climbers experience problems in breathing due to decrease in density. Temperature also decreases with increase in height.
Composition of the Atmosphere. Atmosphere is composed mainly of nitrogen and oxygen. They both make up about 99% of clean, dry air (Nitrogen 78%; Oxygen 21%) Other gases like Carbon-dioxide; argon and others comprise 1% by volume. Oxygen is the breath of life while nitrogen helps in the growth of living organisms. Carbon-dioxide is present …
