It can be found primarily in trenches below the ocean floor. Named after Hades, the Greek god of the underworld, the hadal zone is the deepest part of the ocean. Long thought to be the bottomless end of the sea, the abyssal zone reaches to just above the ocean floor and contains little life due to extremely cold temperatures, high pressures, and complete darkness.

Smaller anglerfish, squid, and sharks live here, as well as a few large organisms like giant squid. Pitch black outside of a few bioluminescent organisms, with no living plants. Contains mainly bacteria, as well as some large organisms like the swordfish and the squid. Stretches from where 1% of surface light reaches to where surface light ends. Illuminated shallower waters that contain most of the ocean’s plants and animals. Open ocean is called the pelagic zone, which can be broken down into five regions by depth: But going below sea level, it actually goes deeper than the height of Everest. How Deep Does the Ocean Go?Ībove sea level, Earth’s topography reaches all the way up to 8,849 meters (29,032 ft) to the top of Mt.

This animation from planetary researcher James O’Donoghue of the Japan Aerospace Exploration Agency (JAXA) and NASA simulates the draining the world’s oceans to quickly reveal the full extent of the Earth’s surface. We might be familiar with a few of the well-known formations on the ocean floor, but there’s a whole detailed “world” that’s as rich as the surface, just waiting to be explored. Hidden from sight lie aquatic mountain ranges, continental shelves, and trenches that dive deep into the Earth’s crust.

Draining the World’s Oceans to Visualize Earth’s SurfaceĪlthough many maps of our planet go into great topographical detail on land, almost two-thirds of the Earth’s surface is covered by the world’s oceans.
