Atmospheric Physics?
It is easy to breathe when snorkeling with only your face below the surface of the water, but quite difficult to breathe when you are submerged nearly a meter and nearly impossible when you are more than a meter deep (even if your snorkle reaches the top of the surface.) Why?
Very briefly and simply: -
Because, as you submerge and, as you go deeper, the pressure of the water is increasing, squeezing your lungs and you have to work harder to inhale.
Even though you don't feel it, there is also a slight panic factor because you're face is submerged..
