Detailed explanation-2: -Trenches are long, narrow and very deep and, while most are in the Pacific Ocean, can be found around the world. The deepest trench in the world, the Mariana Trench located near the Mariana Islands, is 1, 580 miles long and averages just 43 miles wide.

Detailed explanation-3: -The Mariana Trench of the Pacific Ocean, Molly Deep of the Arctic Ocean, Puerto Rico Trench of the Atlantic Ocean, South Sandwich Trench of the Southern Ocean, and the Diamantina Trench of the Indian Ocean are the deepest parts of oceans.

Detailed explanation-4: -An ocean trench is an indentation in the ocean floor and is the deepest area of the ocean. Trenches are formed through subduction, which occurs when tectonic plates collide and push one plate beneath the other. Trenches can be found all over the surface floor of the ocean at subduction zones.
