The Marianas Trench is formed when the 2 oceanic plates converge - the Pacific plate and the Philippines plate. When the Pacific plate is subducted under the Philippines plate, the Marianas Trench is formed.
It is currently estimated to be up to 10,971 m deep
Facts
At the bottom of the trench, where the plates meet, the water column above exerts a pressure of 1,086 bars (15,750 psi), over one thousand times the standard atmospheric pressure at sea level.
The Mariana Trench is the deepest trench in the world.
It is part of the Izu-Bonin-Mariana Arc geological boundary system that forms the boundary between two tectonic plates.
It could be a possible disposal site for nuclear waste

Reflections
We learnt more about the landforms formed as a result of subduction of two oceanic plates. We discovered more about Mariana Trench and it was indeed an eye-opening experience for us. We hope to continue to learn more about geography in the near future.
