Analyze the characteristics of major oceanic trenches and deep-sea basins: Statement I: The Mariana Trench in the western Pacific Ocean contains the Challenger Deep, which is the deepest known point on Earth, formed at a convergent subduction zone where the Pacific plate descends beneath the Mariana plate. Statement II: The Peru-Chile Trench is located in the Atlantic Ocean along the eastern margin of South America, formed by the subduction of the South American plate beneath the African plate.
A. Both Statement I and Statement II are correct
B. Statement I is correct but Statement II is incorrect✓ Correct Answer
C. Statement I is incorrect but Statement II is correct
D. Both Statement I and Statement II are incorrect
💡 Solution & Explanation
Statement one is correct because the Mariana Trench is indeed the deepest oceanic trench, created by active subduction in the western Pacific. Statement two is incorrect because the Peru-Chile Trench is situated in the Pacific Ocean along the western coast of South America, formed by the subduction of the Nazca plate beneath the South American plate, not in the Atlantic Ocean. Subduction zones generate intense seismic and volcanic activity.
