Detailed explanation-1: -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.
Detailed explanation-2: -As altitude decreases, the amount of air over a unit area increases. Therefore, the atmospheric pressure will increase due to the high amount of air molecules.
Detailed explanation-3: -As altitude rises, air pressure drops. In other words, if the indicated altitude is high, the air pressure is low.
Detailed explanation-4: -The most basic change in pressure is the twice daily rise and fall in due to the heating from the sun. Each day, around 4 a.m./p.m. the pressure is at its lowest and near its peak around 10 a.m./p.m. The magnitude of the daily cycle is greatest near the equator decreasing toward the poles.
