Question

The air in the atmospheric reaches 30 kms exerting a lot of pressure on earth. Why don't we get crushed under the weight

Answer 1

A very good question!The atmosphere around us exerts a huge force on us that might have crushed us.But this doesn't happen, we don't get crushed.This is so because the pressure outside our body is balanced by our internal body pressure.Where does this internal pressure comes from?Our body contains blood , and other fluids that applies internal pressure.This pressure is equal to the external pressure (of atmosphere) .Hence, we don't feel the huge weight of air around us!

Answer 2

HeY FriENd HeRe is YoUR AnsWEr :-
We not get crushed under the atmospheric pressure because external (atmospheric) pressure is balanced by internal pressure of our body. Our body also have it's own pressure as it consists blood, lungs etc. That's why we don't get crushed under the atmospheric pressure.
