Key to understanding scuba diving is the concept of pressure, and how it varies with depth. We intuitively understand that pressure is some type of force, but how is it actually defined? Pressure is a force or weight<span> per unit area. All matter, </span>including air<span>, has weight due to earth's gravity.
