Explain how the formation of oceanic trenches and folded mountain belts on continents are related to convergent plate boundaries.

In convergent plate boundaries, one plate subducts under one another due to different density.

Ocean trench- When subduction occurs, a plate would be subducted, and the inbetween of two plates would leave a deep trench due to the motion. One example is the Mariana Trench.

Folded mountain belts- When the plate converge,pressure would be put on the place causing the crust to arch up and be folded. One of example is the Himalayas belt,which occurs when the Indo-Australian Plate and Eurasian Plate collide.

Hope it helps!
