Plate Tectonics and Crustal Features

The diagram below models the movement of two tectonic

plates. What is occurring as a result of the plate collision?

• A mid-ocean ridge is forming.

• Subduction is occurring because oceanic crust is

  denser than continental crust.

• A divergent boundary is forming.

• A transform boundary is forming due to two plates

  sliding past one another.

The most recently formed crust of the Earth would be

found —

• where plates moving sideways passed each other

• where one plate is going under another plate

• where two plates are pushing directly toward each other

• where two plates are moving away from each other in

  opposite directions

The Aleutian Arc is a large volcanic arc which consists of a

grouping of active and dormant volcanoes that have formed along the Aleutian Trench. The Aleutian Arc is a distinguishing feature of the state of

Alaska illustrated above. Alaska is part of the North American Plate. To the South of the

Aleutian Arc is the Pacific Plate. The Aleutian Arc was formed as the Pacific Plate traveled North and the North American Plate traveled West. Based on the information above, which type of plate

boundary caused the formation of the Aleutian Arc?

• Divergent Boundary

• Transform Boundary

• Convergent Boundary

• Strike-Slip Fault Boundary
