The Mariana Trench, located in the Pacific Ocean, is the deepest known part of the Earth's oceans, plunging nearly 36,000 ...

At ocean-ocean convergences, one plate usually dives beneath the other, forming deep trenches like the Mariana Trench in the North Pacific Ocean, the deepest point on Earth.

Plate tectonics is the means through which mountains are formed. The Baird Mountains in Alaska’s Kobuk Valley National Park formed when two tectonic plates along a convergent boundary collided ...

The Mariana Trench, the deepest part of the world’s oceans, has long captivated scientists and explorers alike. Located in ...

The Mariana Trench provides a great venue to test such a question. It's a subduction zone, the boundary of two tectonic plates, where one plate is slowly diving beneath the other.

Though Cameron and his team are hoping to discover more about the biology of the Mariana depths, geologists already know a lot about how the Mariana Trench formed—and why it's Earth's deepest spot.

The Mariana Trench is home to the deepest trough on Earth, the location where the Pacific tectonic plate is subducting beneath the Mariana plate.

The trench is reminiscent of areas where tectonic plates are being subducted on Earth, though nothing about the rest of the feature is at all similar. Bust the crust How do these features form?

When plate tectonics began shaping the Earth's surface has been a matter of debate, but new evidence from ancient rocks in Greenland suggests a start date.
