Plate Tectonics Review

Plate Tectonics Review

Convergent Boundaries

• Collide (crash into eachother)

• Create mountains, trenches, volcanoes

• Destroys crust during subduction

Multiple Choice

How do plates move at CONVERGENT boundaries?

• Collide (together)

• Move apart

• Slide past each other

Multiple Choice

How do CONVERGENT boundaries affect the crust?

• They create crust

• They destroy crust

• They don't destroy or create

Multiple Select

Choose all the features that can be formed at CONVERGENT boundaries.

• Volcanoes/Mountains

• Faults

• Trenches

• Mid Ocean Ridge

• Rift Valley

Subduction

At a convergent boundary, plates collide. Heavier (more dense) oceanic crust goes under and melts into the mantle. This destroys the crust.

Open Ended

Explain subduction.

Divergent Boundaries

• Plates move apart

• Creates mid - ocean ridges and rift valleys

• Creates new crust through Seafloor Spreading

Multiple Choice

How do plates move at DIVERGENT boundaries?

• Collide (together)

• Move apart

• Slide past each other

Multiple Choice

How do DIVERGENT boundaries affect the crust?

• They create crust

• They destroy crust

• They don't destroy or create

Multiple Select

Choose all the features that can be formed at DIVERGENT boundaries.

• Volcanoes/Mountains

• Faults

• Trenches

• Mid Ocean Ridge

• Rift Valley

Seafloor Spreading

At a divergent boundary, two oceanic plates move apart. This allows mantle material to rise and cool, forming new crust. Older crust moves further away.

Open Ended

Explain Sea Floor Spreading.

Transform Boundaries

• Plates slide past each other

• Creates faults

• Does not destroy or create crust

Multiple Choice

How do plates move at TRANSFORM boundaries?

• Collide (together)

• Move apart

• Slide past each other

Multiple Choice

How do TRANSFORM boundaries affect the crust?

• They create crust

• They destroy crust

• They don't destroy or create

Multiple Select

Choose all the features that can be formed at TRANSFORM boundaries.

• Volcanoes/Mountains

• Faults

• Trenches

• Mid Ocean Ridge

• Rift Valley

Multiple Choice

If you lived near a Transform Boundary, what even would you experience?

• Volcanic eruptions

• Earthquakes

• Mountains

• Finding fossils
