The average depth of the oceans is about five times the average elevation of the land. In general, the continents stand about three miles above the ocean floor. According to the National Geographic Atlas, the deepest-known part of the ocean measures 10,924 meters (35,839 feet), in the Marianas Trench near Guam.
