Question
Why is the atmosphere essential for life?
Solution
The atmosphere consists of gases like nitrogen, oxygen, carbon dioxide and water vapour. All these gases are very essential for the survival of organisms. The atmosphere keeps the average temperature of the earth fairly steady and thus makes conditions suitable for the survival of organisms. The atmosphere prevents the sudden increase in temperature during the daylight hours. It also slows down the escape of heat into outer space during the night, keeping the Conditions favourable. Because of all these reasons atmosphere is very important.
