Question

The atmosphere exerts enormous pressure on us. But, we do not feel it because:

  1. Our blood exerts a pressure slightly more than that of the atmosphere.
  2. We are used to it
  3. Our bones are very strong and can withstand the pressure.
  4. The surface area of our head is very small.

Answer:

Option A: Our blood exerts a pressure slightly more than that of the atmosphere.

Detailed Solution:

The correct answer is “Our blood exerts a pressure slightly more than that of the atmosphere.”.

Humans don't feel the pressure of the atmosphere because the pressure inside our bodies is slightly higher than the atmospheric pressure, so it balances it out.
