The Mariana Trench is 1,580 miles (2,542 kilometers) long â more than five times the length of the Grand Canyon. However, the narrow trench averages only 43 miles (69 km) wide. Because Guam is a U.S. territory and the 15 Northern Mariana Islands are a U.S. Commonwealth, the United States has jurisdiction over the Mariana Trench.
Its maximum length is about 15,500 km (about 9600 mi) from the Bering Strait to Antarctica, and its greatest width is about 17,700 km (about 11,000 mi) from Panama to the Malay Peninsula. Its mean depth is 4282 m (14,049 ft). The greatest known depth in any ocean is 11,033 m (36,198 ft) in the Mariana Trench off Guam. http://www.history.com/encyclopedia.do?a...
