The deepest trench in the world is the Mariana Trench, also known as the "Mariana Islands Trench". Its deepest point is -11,034 meters in the Fitchas Abyss, which is currently the deepest point on Earth.

Which is the deepest trench in the world?

The formation of trenches is generally caused by collisions between the earth's crust, so trenches are easily formed where collisions occur. Island arcs, back-arc basins and coastal mountains are often formed on the side of the continent, which are areas with intense geological activity. Volcanic eruptions and earthquakes often occur, and trenches are easily formed.

The Mariana Trench, also known as the "Mariana Islands Trench", is located at the bottom of the Pacific Ocean near the northeastern Philippines and the Mariana Islands, between the Asian continent and Australia. It is the deepest trench in the world, with a depth of more than 10,000 meters, exceeding the highest height of Mount Everest.
