## Why can’t Humans go to the bottom of the ocean?

The intense pressures in the deep ocean make it an extremely difficult environment to explore.” Although you don’t notice it the pressure of the air pushing down on your body at sea level is about 15 pounds per square inch.

## Why is the ocean salty?

Ocean salt primarily comes from rocks on land and openings in the seafloor. … Rocks on land are the major source of salts dissolved in seawater.
