The highest point above sea level on Earth is the summit of Mount Everest, at 29,032 feet (8,848 meters). The lowest point below sea level is the Challenger Deep in the Mariana Trench, which goes down to 36,070 feet (10,994 meters).
The Hadal zone, also known as the hadopelagic zone or the trench zone, is found from 20,000 feet (about 4 miles) below sea level to the ocean floor.
