GENERAL KNOWLEDGE

Detailed explanation-1: -Then explain to students that the Mariana Trench is the deepest part of the ocean and the deepest location on Earth. It is 11, 034 meters (36, 201 feet) deep, which is almost 7 miles.

Detailed explanation-2: -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. Challenger Deep is approximately 10, 935 meters (35, 876 feet) deep.

Detailed explanation-3: -Located in the western Pacific east of the Philippines and an average of approximately 124 miles (200 kilometers) east of the Mariana Islands, the Mariana Trench is a crescent-shaped scar in the Earth’s crust that measures more than 1, 500 miles (2, 550 kilometers) long and 43 miles (69 kilometers) wide on average.

Detailed explanation-4: -One reason the Mariana Trench is so deep, he added, is because the western Pacific is home to some of the oldest seafloor in the world-about 180 million years old. Seafloor is formed as lava at mid-ocean ridges. When it’s fresh, lava is comparatively warm and buoyant, riding high on the underlying mantle.
