Convergent Plate Margins - oc-cont

Which plate is subducted at oceanic-continental convergent boundaries?

Thinner and denser oceanic crust.

What happens to the subducted crust?

It melts and creates new magma that feed magma chambers that create continental volcanic arcs.

What does friction along the Benioff zone and subduction zone result in?

Earthquakes of various magnitudes occurring at a variety of depths.

What does the downward displacement of oceanic crust create?

An oceanic trench and sediments on the edge of the continental plate are deformed by the plate movement creating young fold mountains.

How does an oceanic trench run in regards to the plate boundary?

The trench runs parallel to the plate boundary.

What is the deepest part of the ocean (actually oceanic-oceanic)?

The Challenger Deep, in Marianas Trench at just over 10,900 metres deep.

What happens to sediments during subduction?

Sediments accumulate on the edge of the continental plate, and are then deformed by folding and faulting and then uplifted to form young fold mountains.

What are fold mountains?

Parallel chains of high volcanic mountains with an inter-montane plateau between them.
