GEOLOGY

Detailed explanation-1: -The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.

Detailed explanation-2: -In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. At 35, 814 feet below sea level, its bottom is called the Challenger Deep-the deepest point known on Earth.

Detailed explanation-3: -The Mariana Trench, in the South Pacific Ocean, is formed as the mighty Pacific plate subducts beneath the smaller, less-dense Philippine plate. In a subduction zone, some of the molten material-the former seafloor-can rise through volcanoes located near the trench.

Detailed explanation-4: -The deepest place in the Atlantic is in the Puerto Rico Trench, a place called Brownson Deep at 8, 378m. The expedition also confirmed the second deepest location in the Pacific, behind the Challenger Deep in the Mariana Trench. This runner-up is the Horizon Deep in the Tonga Trench with a depth of 10, 816m.

Detailed explanation-5: -Appearing as a crescent-shaped scar in the Earth’s crust, the trench measures around 2, 550 km long, 69 km wide on average, and has a maximum depth of 10.91 km at the Challenger Deep. At the same time, some other efforts measured the deepest portion at 11.034 km.
