What happens to the pressure on a diver as the go under water?

Pressure Increases With Depth The deeper a diver descends, the more water they have above them, and the more pressure it exerts on their body. The pressure a diver experiences at a certain depth is the sum of all the pressures above them, both from the water and the air.

How deep can humans dive before being crushed by pressure?

about 35.5 km
