Question

diver wear a metallic cover while going into a sea. why??

Answer 1

Pressure is Directly proportional to the depth. Which means that as we go down the sea into the depth, pressure increases and hence to protect ourself from this huge pressure we must wear a swimming suit.

Answer 2

The more one goes deep in water, the more is the pressure and a point comes when the presuure becomes unwithstandable for human body. So divers wear this this special cover to protect themselves from the exerted pressure. It also keeps them warm.
