Question

what is the change in atmospheric pressure as we go up from sea level​

Answer 1

Answer:

Atmospheric pressure decreases with increases in the altitude. As we know that the density of air becomes heavier near the surface of the earth (due to gravity) and begins to lighten as we go to higher altitudes and eventually leads to empty space, i.e. outside the atmosphere of the earth.

Answer 2

Answer:

Atmospheric pressure decreases as we go up from sea level as the surface above ground level increases. This is because, as the altitude increases: the number of air molecules decreases.
