Plate Tectonics Test

The North American plate and Pacific plates meet at the San Andres Fault in California causing frequent earthquakes. This fault is located at a _____ boundary.

• Ridge

• Divergent

• Convergent

• Transform

Which oceanic plate in the above picture must be more dense? LEFT RIGHT

• The plate on the left (the plate with the volcano on it)

• The plate on the right (without the volcano)

Which TWO landforms occur when a continental plate and an oceanic plate hit each other?

• Volcanoes on land and Volcanic Islands

• Volcanoes on land and Deep Sea Trench

• Volcanoes on land and Mountains

• Rift Valley and Mid Ocean Ridge

How do most mountains form?

• Continents collide and fold up on each other

• Earth is shrinking and the crust wrinkles up

• Ocean plates diverge and fold up on each other

• Gravity from the moon pulls sections of the Earth up

What kind of landform is created when a continent starts to get torn apart?

• Volcanic Island

• Deep Sea Trench

• Mid-ocean Ridge

• Rift Valley

• Mountains

Plates are not created or destroyed: They just pass by each other.

• Converge

• Diverge

• Transform

This is where new material is added on to plates.

• Converge

• Diverge

• Transform

This is where plate material may be destroyed (or recycled) and returned to the mantle.

• Converge

• Diverge

• Transform

What forms when two CONTINENTAL plates CONVERGE?

• Rift Valley

• Mid Ocean Ridge

• Mountains

• Volcanoes on land and ocean trench

What are these plates doing?

• Diverging

• Converging

• Forming a transform boundary
