EVERYDAY SCIENCE

Detailed explanation-1: -Explanation: because atmospheric pressure decreases with the increase in the altitude. So, mountains have high altitude than that of the sea, the sea coast, the plateau. So, on the mountain the atmospheric pressure is the lowest.

Detailed explanation-2: -The lowest measurable sea-level pressure is found at the centres of tropical cyclones and tornadoes, with a record low of 870 hPa (12.6 psi; 26 inHg).

Detailed explanation-3: -As altitude rises, air pressure drops. In other words, if the indicated altitude is high, the air pressure is low. This happens for two reasons. The first reason is gravity.

Detailed explanation-4: -At sea level, the atmospheric pressure would be a little over 100 kPa (one atmosphere or 760 mm Hg). If we climb to the top of Mount Everest (the highest mountain in the world at 29, 029 feet or 8848 meters), the atmospheric pressure will drop to slightly over 30 kPa (about 0.30 atmospheres or 228 mm Hg).

Detailed explanation-5: -Air pressure is higher at Earth’s surface and decreases as you go upward in altitude, or elevation. Air is more dense at Earth’s surface, meaning the particles are more tightly packed together, so the particles collide more frequently. The column of air pressing down from above is also greatest at Earth’s surface.
