Oceanic/Oceanic Plate Boundary
Transcript of Oceanic/Oceanic Plate Boundary
Describe what physical features are formed at or near this boundary.
Where on the Earth do these boundaries occur
What does each plate do at the boundary
The plates gets pulled under each other. This forms what is called a subduction zone. As the oceanic crust sinks, a deep oceanic trench is formed at the edge of the continent. The crust will continue to be forced deeper into the earth.

What is an Oceanic/Oceanic Plate Boundary?
An Oceanic/Oceanic plate boundary is when a subduction zone is formed at a convergent plate boundary, when one or both of the tectonic plates is composed of oceanic crust. The denser plate, made of oceanic crust, is then subducted underneath the less dense plate.
Deep Sea Trenches are formed, volcanoes, and island arcs.
Japan, the Aleutian islands and the Eastern Caribbean islands of Martinique, St. Lucia and St. Vincent and the Grenadines are examples of islands formed through this type of plate boundary.
Puerto Rico Trench.
As the South American Plate moves west, due to seafloor spreading at the Mid Atlantic Ridge, it will eventually subduct itself beneath the Caribbean Plate.
