The Mariana Trench, between the Mariana Islands and Guam, is believed to be the lowest point on the Earth’s surface.
It is about 36,000 feet below sea level.
The trench is about 1,580 miles long and has a depth that is taller than Mount Everest.
The Mariana Trench has been proposed as a site for nuclear waste disposal because the nuclear waste would slowly be pushed deep into the Earth’s mantle.
But dumping of nuclear waste in the ocean is banned by international law.
The lowest point bounded by land is the Dead Sea, between Jordon and Israel.
It lies about 1,300 feet below sea level.
