A trench is a trench located in the ocean with two walls that are steep, narrow and deeper than 5000m (for example, the Mauritius Trench 5564m). It is the deepest part of the ocean floor and the maximum water depth can reach more than 10,000 meters (Mariana Trench 11034m). .
A long and narrow seabed with a depth of more than 5000 meters. The slopes on both sides are steep and distributed on the edge of the ocean. Such as the Philippine Trench in the Pacific and the Puerto Rico Trench in the Atlantic.

The Mariana Trench is a deep ditch formed by the Pacific plate subducting from the east to the west under the Philippine plate. 2 550km, with an average width of 70km. Most of the water depth is above 8000m. The southern section of the Mariana Trench is about 200km southwest of Guam. The trench extends near east-west, with a maximum water depth of more than 10,000m. It is also the deepest place on the planet, known as the Challenger Abyss [1] .
