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. The Challenger Deepregion of the Mariana Trench has the maximum known depth, at 6.831 miles below sea level. This area is located in the western Pacific Ocean, just east of the Mariana Islands.See the related Wikipedia link listed below for more information:
According to the Wikipedia article - It reaches a maximum-known depth of about 6.78 miles (10.91 kilometres) at its deepest point
It is known as a trench, which is the lower part of the ocean. The deepest trench is the Marina Trench.
Mariana's Trench, the deepest part of the Pacific Ocean, is around 35,000 feet deep. That is nearly 7 miles.
It is 11,034 meters (36,201 feet) deep, which is almost 7 miles. Tell students that if you placed Mount Everest at the bottom of the Mariana Trench, the peak would still be 2,133 meters (7,000 feet) below sea level.

The lowest point relative to "sea level" of Mars (officially measured relative to the "reference ellipsoid" for Mars) is Hellas Planitia. This huge impact crater is about 7km (4.5 miles) below the reference ellipsoid (below "sea level"). By comparison, the Challenger Depth in the Marianas Trench is the lowest point on the Earth's surface and is about 11km below sea level. (The lowest land elevation is the Dead Sea -- 422m below sea level. Water likes to fill in hole on the earth's surface!)
The ocean trench is almost 7 miles deep.
35,994 feet. That is 6.8170454 miles. At that depth, an unprotected human would be crushed faster than his brain could register the injury.
Death Valley National Park is 5,216 square miles.
The depth of a oceanic trench can vary. But the largest trench discovered is called the Mariana Trench that is 1,554 miles long, 44 miles wide and almost 7 miles deep, situated in the Pacific Ocean. Reference: http://www.ocean.udel.edu/deepsea/level-2/geology/deepsea.html
