Mariana Trench According to Encyclopedia Britannica Mariana Trench is the deepest place on the Earth. It is located in the Western Pacific Ocean, Eastern of the Mariana Islands. Its coordinates are 11"21' North latitude and 142" 12' East longitude. Its depth is equal to 11033 meters (36201 feet) the length is 2542km (1580 miles long), and the width of the trench is 69km (43miles) wide. The length is five times greater than the length of the Grand Canyon.
According to the www.livescience.com website The Mariana Trench was created by a process that occurs in a subduction zone where two parts of oceanic crust collide (subduction is a process when one tectonic plate collides with another and submerges under it slowly sinking …show more content…
This depth was reached by Trieste, a manned submersible owned by the U.S. Navy in 1960. According to www.marianatrench.com, if we were to put the Mountain Everest which is the tallest place on Earth 8850 meters (29035 feet) in the Mariana Trench there would still be 2183 meters (7166 feet) of water left above it. Although the Trench is very deep it is actually not the spot closest to the center of the Earth. Because the planet bulges at the equator, the radius at the poles is about 25 km (16 miles) less than the radius at the equator. The pressure on the floor of the trench is more than 8 tons per square inch (703 kilograms per square meter), which is more than 1000 times the pressure at the sea level. Because of this, parts of the Arctic Ocean seabed are closer to the Earth's center than the Challenger …show more content…
It is home to many different species of invertebrates and fish that had to evolve in perpetual darkness. The Challenger Deep in the Mariana Trench is very cold, and highly pressurized which forces all of the living things that live there to adapt to its conditions. The floor of Challenger Deep features hydrothermal vents formed by spreading tectonic plates which release hydrogen sulfide and other minerals which are consumed by the basophilic bacteria which are then consumed by other microorganisms, which are consumed by fish. Crabs, Anglerfish, Ghost fish and many bacteria type beings are just but a little part of the Mariana Trench’s inhabitants. One mud sample taken from Challenger Deep by Oceanographers from the Kaiko yielded nearly over 200 different microorganisms. Although there seems to be an abundance of life at these depths, no human being could withstand the pressure extremes. The ocean floor at such depth consists of pelagic sediment, also known as biogenous "ooze". Pelagic sediment is composed of shells, animal skeletons, decaying microorganisms and plants; it is generally yellowish and very
