Which place has the deepest point on Earth?

The deepest known point on Earth is the Challenger Deep, located in the Mariana Trench near Guam in the western Pacific Ocean. Its depth is commonly given as about 10,900 to 11,000 meters, or roughly 11 kilometers, below sea level. The exact figure can vary slightly depending on the survey method and location within the trench. The first crewed descent to this area was made by the bathyscaphe Trieste in 1960, and later by deep-diving submersibles and landers. This extreme depth makes it the lowest point in the world’s oceans and one of the most studied hadal environments.
