Ocean depths. About 71% of the Earth is covered in water and the average depth is 12,080 feet — which is nearly as deep as Mount Fuji is tall, according to Woods Hole Oceanographic Institute.

Covering 70% of Earth’s surface, the average depth of the ocean is 3,682 metres. The lower you go the higher the hydrostatic pressure (the force per unit area exerted by a liquid on an object).

Here’s a look at the ocean where the Titanic went down on April 14, 1912. According to NOAA, the average ocean depth is 12,566 feet. The greatest ocean depth, however, is 36,200 feet.
