Correct Option (B)
The correct match is I-B, II-C, III-A, IV-D.
- The Aleutian Trench is located in the North Pacific Ocean, extending from the Gulf of Alaska to the Kamchatka Peninsula. It is formed by the subduction of the Pacific Plate under the North American Plate.
- The Kermadec Trench is situated in the South Pacific Ocean, northeast of New Zealand. It is formed by the subduction of the Pacific Plate under the Indo-Australian Plate.
- The Sunda Trench, also known as the Java Trench, is located in the northeastern part of the Indian Ocean, off the coast of Sumatra and Java. It is formed by the subduction of the Indo-Australian Plate under the Eurasian Plate.
- The South Sandwich Trench is found in the South Atlantic Ocean, east of the South Sandwich Islands. It is formed by the subduction of the South American Plate under the Sandwich Plate.
Incorrect Options:
Options A, C, and D are incorrect as they propose different pairings that do not accurately reflect the geographical locations of the oceanic trenches. For instance, Option A incorrectly places the South Sandwich Trench in the South Pacific Ocean and the Kermadec Trench in the South Atlantic. Option C incorrectly places the Aleutian Trench in the Indian Ocean and the Sunda Trench in the North Pacific. Option D incorrectly places the Aleutian Trench in the Indian Ocean and the Sunda Trench in the North Pacific, similar to Option C, and also mislocates the Kermadec Trench. The correct associations are crucial for understanding global plate tectonics and oceanography.
