TYPES OF PLATE BOUNDARIES

A subduction zone is formed...

• at transform boundaries

• when an ocean plate sinks below a continental plate creating a mountain range

• when an ocean plate sinks below a continental plate creating a trench and usually volcanoes

• when an ocean plate sinks below a continental plate creating a mid-ocean ridge and rift valley

Which type of boundary is known for causing big earthquakes?

• CONVERGENT

• DIVERGENT

• TRANSFORM

• SUBDUCTION

Continental crust and continental crust come toward each other at a convergent plate boundary. This will likely form...

• mid-ocean ridge

• mountains

• rift valley

• volcano

Oceanic crust (sea floor) is destroyed at this boundary.

• CONVERGENT-CONVERGENT PLATE BOUNDARY

• OCEANIC-OCEANIC PLATE BOUNDARY

• OCEANIC-CONVERGENT PLATE BOUNDARY

• DIVERGENT PLATE BOUNDARY

The process that occurs at a divergent oceanic boundary that creates new crust (sea floor) is called?

• Continental Drift

• Seafloor Spreading

• Subduction

• Volcanism

Aside from Earthquakes, what is the only thing you will find at transform boundaries?

• Fault lines

• Folded Mountains

• Subduction Zones

• Volcanoes

What is the only event associated with ALL plate boundaries?

• Deep Trenches

• Earthquakes

• Subduction

• Volcanoes

How is it possible for new crust to be formed without increasing the surface area of the Earth?

• Crust is destroyed at the same time it is created

• New crust is underwater where it sinks

• New crust breaks more easily than old crust

• Nothing happens

The oceanic crust usually subduct beneath the continental crust when they collide because it is

• denser than continental crust

• less dense than continental crust

• thicker than continental crust

• thinner than continental crust

Which plate boundary is formed between the Philippine plate and the Eurasian plate?

• CONVERGENT

• DIVERGENT

• TRANSFORM

• SUBDUCTION
