Standard atmospheric pressure Standard atmospheric pressure (atm) in pascals is 1013.25 hPa = 760 mm Hg = 29.9212 inches Hg = 14.696 psi Changing the barometric pressure can affect our mood, in sensitive people it … The uneven heating causes temperature differences, which in turn cause air currents (wind) to develop, which then move heat from where there is more heat (higher temperatures) to where there is less heat (lower temperatures). Skin adjusts easily to changes in pressure, but the cavities within the body, such as the lungs, ears and sinuses, do not adjust automatically. (p) Caused by high speed wind and air pressure differences. The same amount of air occupies more space when it heats up than when it is cold. The envelope of air surrounding the earth is called atmosphere. It's because it's really a measure of the weight of all the air pressing down at that point. answer choices . wind.
