• mountain

• earthquake epicenter

Which of the following is the result of the collision of two oceanic plates?

• trench

• volcano

• rift valley

• fault line

Why does the oceanic crust sink beneath the continental crust at then subduction zone?

• The oceanic crust has a greater density.

• The oceanic crust is pulled downward by Earth’s magnetic field.

• The oceanic crust is pushed from the ridge.

• The continental crust has a denser composition.

• The volcanoes on the edge of a continent will form.

• The volcano along the mid-oceanic ridge will form.

The image on the left is Mount Pinatubo. It is a result of the convergence of the Eurasian and Philippine plates. What type of convergent boundary occurred to form Mount PInatubo?
