How does the atmospheric pressure at altitudes above sea level compare with atmospheric pressure at sea level? A. The atmospheric pressure above sea level is higher.
B. The atmospheric pressure at sea level is higher.
c. The pressures are the same.
D. Differences in pressures cannot be determined.

Option B

The atmospheric pressure at sea level is higher.

Explanation:

Atmospheric pressure can simply be understood as the weight of the air molecules in the atmosphere. The higher we go up into the atmosphere, the thinner the air becomes. This means that the air present at higher heights is not so much, and hence, the air is lighter. This is why most fighter jets and mountain climbers need oxygen tanks to breathe properly.

Due to the fact that the air is less dense (lighter) at higher altitudes, it also means that the atmospheric pressure at higher altitudes is less.

Therefore, the atmospheric pressure at the sea level is higher than the atmospheric pressure at  altitudes above sea level
