What type of convergent plate boundary is found in the western pacific ocean eat of Australia where the Mariana trench is as much as 35000 feet below sea level?

The convergent plate boundary found in the western Pacific Ocean east of Australia, where the Mariana Trench is located, is a subduction zone. In this region, the Pacific Plate is being forced beneath the smaller Mariana Plate, leading to the creation of deep oceanic trenches and volcanic activity. This ongoing process results in significant geological features, including the extreme depths of the trench, which is the deepest point in the world's oceans.
