Convergent Oceanic/Oceanic Flashcards
1
Q
What happens when an oceanic and oceanic plate meets
A
One is forced under the other and the processes involved with the subduction begin.
2
Q
What features are associated with the subduction of oceanic/oceanic convergence
A
Ocean trenches and island arcs, as it takes place well offshore
3
Q
Example of an oceanic/oceanic convergence
A
On the Western side of the Pacific Ocean where the Pacific plate is being subducted beneath the smaller Philippine plate. The ocean floor has been pulled down to form the very deep Marianas trench. A line of volcanic islands, including Guam and the Marianas, has been formed by upswelling magma from the Benioff zone.
