Deepest Ocean Points: Western Pacific (Mariana Trench) vs. Eastern Pacific (Peru–Chile Trench)

• Western Pacific (deepest on Earth): Challenger Deep, Mariana Trench — ~11,034 m (36,201 ft).
• Eastern Pacific: Molloy Deep (often called Richards Deep), Peru–Chile Trench — ~8,065 m (26,460 ft).

The western Pacific's subduction zones produce far greater depths than the eastern margin.
