The Mariana Trench stretches 2,500 kilometers (1,500 miles) in an arc that is edged by islands such as Guam and Saipan. It is the deepest trench in the world’s deepest ocean, and now scientists have a new map of it. Using sound waves, scientists have pierced the lightless depths of the western Pacific Ocean and drawn a new picture of the Mariana Trench. Its depths (nearly 11,000 m)easily dwarf the tallest mountains on Earth’s surface and pressures exceed 1,000 atmospheres, or 1,000 times the air pressure at the land surface. The trench was formed (and is constantly remodeled) by...
