Which ocean trench, the deepest known depression on Earth's seabed, is located in the western Pacific Ocean near the Mariana Islands?

💡 Solution & Explanation

The Mariana Trench is located in the western Pacific Ocean and contains the Challenger Deep, which is the deepest point in the Earth's oceans. It is formed by subduction where the Pacific Plate is being forced beneath the smaller Mariana Plate. Other trenches like the Java Trench are located in the Indian Ocean basin.
