As the continental shelf gives way to the ocean depths, trenches and canyons gouge into the Earth's crust. Submarine canyons, underwater erosion, and drainage systems analogous to above-water ...

What's at the bottom of the Mariana Trench, and how do we know? How deep does the ocean go? We'll answer these questions and more in this deep dive into the world's oceans.

The search of Malaysia Airlines Flight 370 didn't uncover the missing airliner, but revealed previously undiscovered volcanoes, mountain ridges and deep trenches studded with shipwrecks and anchors.

The results also shed light on seafloor tectonics, or the movements of massive oceanic plates that can shape the rifts, ridges and trenches decorating the ocean bottom. Here's a look at what the ...
