As you go deeper in the ocean, the pressure exerted by the water increases. For each additional meter below the surface, pressure increases by 10 kPa. Water pressure makes it difficult to explore the deep ocean. The pressure is too great for divers unless they travel in pressure-resistant deep-sea vehicles.
Why can’t divers go too deep?
Nitrogen narcosis: Deep dives can cause so much nitrogen to build up in the brain that you can become confused and act as though you’ve been drinking alcohol. You might make poor decisions, such as taking out your regulator because you think you can breathe underwater.
