Geographical Features of Mariana Trench
Mariana Trench is the deepest point in the world located in the western part of the North Pacific Ocean. Mariana Trench is placed in the south-east of the Mariana Islands and located in the middle of Indonesia and Japan.
Dimensions of Mariana Trench
The Mariana Trench has a form of a crescent. It took many year to determine the exact depth of the trench due to technical difficulties. Although results of the surveys conducted over the years have produced different results, it has been proven that today the deepest point of the Mariana Trench is about 10994 meters below sea level. The deepest point of the Mariana Trench is called Challanger Deep. Mariana Trench is also 2542 kilometres long and 69 kilometres wide.
Formation of Mariana Trench
The collision of different plates under the ocean leads to weak plates getting broken and earthquakes . In such collisions, one of the plates slides underneath another and sinks under the earth’s crust. The researches show that the Pacific Plate and the Philippine Plate collided and resulted in the formation of Mariana Thrower. The Pacific Plate, a 180-million-year-old tectonic plate, slips under the younger and smaller Philippine Plate.
