Answer» if your ears have even proped on a plane flight or ached during a deep dive in a swimming pool we have experienced the effect of depth on pressure in a fluid. at the earth surface the air pressure exerted on you is a RESULT of the weight of air above you decreases under water the pressure exerted on you increases with increasing depth in this case the pressure being exerted upon you is a result of both the weight of water above you and that of the atmosphere above you you MAY notice an air pressure change on an elevator ride that transports you many stories but you need only five a meter or so below the surface of a pool to feel a pressure INCREASE the DIFFERENCE is that water is much denser than air about 775 times as DENSE |
