The lowest point of _______ is Challenger Deep in the Mariana Trench.

The correct answer is the Pacific Ocean.

• The lowest point of the Pacific Ocean is Challenger Deep in the Mariana Trench.

Key Points

• The Mariana Trench is part of a global network of deep troughs that cut across the ocean floor.
• They form when two tectonic plates collide.
• At the collision point, one of the plates dives beneath the other into the Earth’s mantle, creating an ocean trench.
• Located in the western Pacific east of the Philippines and an average of approximately 124 miles (200 kilometers) east of the Mariana Islands.
• The Mariana Trench is a crescent-shaped scar in the Earth’s crust that measures more than 1,500 miles (2,550 kilometers) long and 43 miles (69 kilometers) wide on average.
• The distance between the surface of the ocean and the trench’s deepest point the Challenger Deep, which lies about 200 miles (322 kilometers) southwest of the U.S. territory of Guam is nearly 7 miles (11 kilometers).
• If Mount Everest were dropped into the Mariana Trench, its peak would still be more than a mile (1.6 kilometers) underwater.
• The majority of the Mariana Trench is now a U.S. protected zone as part of the Marianas Trench Marine National Monument, established by President George W. Bush in 2009.

Additional Information

• Java Trench, also called Sunda Double Trench, deep submarine depression in the eastern Indian Ocean that extends some 2,000 miles (3,200 km) in a northwest-southeast arc along the southwestern and southern Indonesian archipelago.
• The deepest part of the Atlantic Ocean is situated in the Milwaukee Deep within the east-west oriented Puerto Rico Trench.
  • Which is located around 120 km north of the island of Puerto Rico
