Plate Boundaries

What kind of plate boundary is shown here?

• divergent
• convergent
• transform
• submergent

What geologic feature/event would you most likely to find at a divergent boundary between two pieces of oceanic crust?

• Rift Valley
• Mid-Ocean Ridge
• Island Arc
• Flat land

What geologic feature/event would you most likely to find at a convergent boundary between two pieces of continental crust?

• Volcano
• Mountain
• Rift
• Island Arc

A subduction zone is formed...

• when one tectonic plate sinks below another
• at every type of convergent plate boundary
• at every type of divergent plate boundary
• at transform boundaries

Sometimes, when two tectonic plates collide, one is pushed below the other; this action at the convergent boundary is called...

• Divergent boundary
• Convergent boundary
• Transform boundary
• Subduction

When an oceanic plate is subducted under a continental plate, a deep valley is formed in the ocean. What is this valley called? 

• a trench
• a rift zone
• ocean spreading ridge
• Continental crust

Creates new ocean floor:

• Divergent
• Convergent
• Transform

Has rift valleys:

• Divergent
• Convergent
• Transform
• Actually, all of them

Upwelling of magma:

• Divergent
• Convergent
• Transform
• Actually, all of them

Recycles old crust:

• Divergent
• Convergent
• Transform
• Actually, all of them
