There are at least 22 trenches that have been identified by the scientists. The scientists have assured that there are 18 trenches in the Pacific Ocean, three in the Atlantic Ocean, and one in the Indian Ocean. A trench is the deepest part of the earth’s ocean, in fact it is the deepest location of the earth itself and it was created by ocean-to-ocean subduction. A situation where a plate of an oceanic crust is subducted beneath another place of an oceanic crust, this happens when the earth crust moved under water. The Marianna Trench is located in the Pacific Ocean near Japan but exactly how deep is the Mariana Trench?
The average depths of the earth’s ocean will give you a rough idea of how deep is the Mariana Trench. The Arctic Ocean is one of the shallowest among all the ocean standing with 1,038 meters or 3,407 feet deep, the Indian Ocean is 3,872 meters or 12,740 feet deep, while the Atlantic Ocean is 3,872 meters or 12,254 feet deep and the Pacific ocean, the ocean where Mariana Trench is located is 4,188 meters or 13,740 deep.
The Pacific Ocean’s Mariana Trench is the deepest point of the earth, standing in 11,0033 meters or 36,201 deep. The deepest point of the Mariana Trench is called the Challenger Deep, name after the famous British exploration vessel HMS Challenger II that found the point to remember the achievement, it is located 210 miles of the southwest of Guam. However, the Challenger Deep was first reached in 1960 by the United States of America using a manned submersible, which is owned the U.S. NAVY called the Trieste.
In order to get a better picture of the actual depth of the Mariana Trench, we are going to use the tallest point of the earth, which is the Mount Everest standing at 8,850 meters or 29,035 feet. If Mount Everest were to sink in the Mariana Trench, there would still be 2,183 meters or 7,166 feet of water left above the Mount Everest. Due to it’s depth, the Mariana Trench is the passage used by submarines because if is a part of long system of trenches in the Pacific Ocean.
