At the bottom of the trench the water column above exerts a pressure over 1000 times the standard atmospheric pressure at sea level

Result

Your answer: — · Correct: A

Explanation

The Mariana Trench is located in the Western Pacific Ocean, but it lies to the east of the Mariana Islands, not the west [4]. The trench is formed where the Pacific Plate subducts beneath the Mariana Plate to the west [4]. Other statements are accurate: the trench was first sounded by the HMS Challenger expedition in 1875, which recorded depths exceeding 8,000 meters [3]. It measures approximately 2,550 kilometers (1,500 miles) in length with an average width of 69 kilometers (43 miles) [4]. Furthermore, the hydrostatic pressure at the bottom of the trench (Challenger Deep) is immense, reaching over 1,000 times the standard atmospheric pressure at sea level, approximately 15,750 pounds per square inch [4].
