The deepest point in the ocean lies in the Mariana Trench in the Pacific Ocean. The Mariana Trench is located in the western part of the Pacific Ocean near the fourteen Mariana Islands. The shape of the Mariana Trench is that of a semi-circle. It extends northeast to southwest for about two thousand five hundred fifty meters and is seventy kilometers wide. The Mariana Trench was formed by the process of subduction. The interior of the earth or the mantle is composed of lava. The solid crust of the earth which are in pieces are on top. Sometimes the lava from the mantle rises up through the cracks in the crust. This either causes pieces of the crust to be pushed together or apart. So when the oceanic crust which is heavier is pushed against the continental crust which is lighter, the oceanic crust is pushed to the bottom and the continental crust to the top. Then oceanic crust or subducted crust forms the trench.

The deepest point in the Mariana Trench and in the oceans is Challenger Deep which is three hundred and forty kilometers off the coast of Guam. Mount Everest which is the highest point on the Earth's surface 5.49 miles is more than 1 mile shorter that the Challenger Deep (the deepest point in the ocean at 6.86 miles).

Challenger Deep was named after the HMS Challenger II who discovered the point in 1948. In 1960, Jacques Picard and Navy Lieutenant Donald Walsh took the bathyscaphe Trieste into Challenger Deep. They took the Trieste into the deep ten thousand nine hundred and fifteen meters.

At the bottom of the Mariana Trench, water exerts a pressure of 1086 bar (108.6 MPa or 15,751 psi). The pressure in Challenger Deep with almost seven miles of water overhead is 16,000 pounds per square inch !

Answer 3

The deepest place in the ocean is the Mariana Trench. It is 36,090 feet deep.

The pressure there is 1,093 atmospheres, this converts to 15,500 pounds per square inch.
