Question

Where is the air pressure greater—at sea level or on a mountaintop? Explain.

Answer 1

The air pressure or the barometric pressure is usually denser near or below the sea level.

This happens because the air pressure goes down as the altitude increases.

Since with the increase in altitude the atmospheric condition becomes thinner the air pressure goes down.

It has been observed that in Siberia, some 2000ft.

Below the sea level the barometric pressure is most dense.
