I understand that the deeper you dive into the ocean the more pressure you will face. I also know it’s a gradual change in pressure. But how is that pressure created?
In: 5
Whenever you are in the water you really have a column of water on top of you all the way to the surface, you are basically being crushed by that water as if you were carrying a bunch of rocks on your head.
The deeper you go the more water is above you and the greater the weight. This weight is what we call pressure.
It might seem strange but the same is true for air as well. At sea level the pressure around you is 1 “atmosphere”, 1 atmosphere is equal to about 15 pounds per square inch, meaning that the air above you presses down on you with 15 lbs of pressure on each square inch of your body.
