A Transform Fault ZoneIn the textbook Earth Science and the Environment (4th Edition) by Thompson and Turk. Located on page 163, it shows that Tonga has a Convergent Boundary. A convergent boundary is where two lithospheic plates collide head on.
The Mariana Trench is the deepest trench in any of the world's oceans. It's in the western Pacific, east of the Mariana Islands (south of Japan and north of Papua New Guinea). The trench is located on a convergent (coming together) plate boundary where subduction is occurring (one plate is being pushed underneath the other). Trenches are a common occurrence at convergent land-sea plate boundaries.the Mariana trench is the longest trench in the world its in the pacific ocean
