PHYSICS [2 Mark Question Answer]

"At deep waters, the column of water above the diver exerts a pressure and this pressure is very high due to the weight of water above the diver up to the surface. The diving suits are required to enable diver to withstand these pressures and swim comfortably.
Hence, Deep sea divers wear specially designed suits to protect themselves from high pressures."

Water pressure is the result of the weight of all the water above pushing down on the water below. As you go deeper into a body of water, there is more water above, and therefore a greater weight pushing down. Hence This is the reason water pressure increases with depth
