Question

deep sea divers must use specially designed suits.why?

Answer 1

As go in depth of waters.. the pressure applied by the atmosphere combined by the large volumes of water above you increase.. as the volume of water above you increases.. our bodies.. can't withstand such high pressures.. as one's blood vessels would burst and he would be bleeding.. to prevent that for a certain degree of deepness.. we use specially designed suits to keep the pressure inside the suit favourable to the human body and counteracting to the pressure of water to a certain amount of pressure.
