Plate Boundaries

The diagram shows a landform on Earth. How did the movement of Earth’s plates form the landform?

• Two oceanic plates slid past each other.

• Two continental plates collided.

• One continental plate slid past an oceanic plate.

• One continental plate subducted beneath an oceanic plate.

The diagram shows a cross section of a portion of the Earth. Which letter represents a mid-ocean ridge?

• W

• X

• Y

• Z

Which diagram shows a plate boundary that is typical for the formation of volcanoes?

• 
• 
• 
• 

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

When convergent plates collide, if both plates are pushed upward, this forms.  

• Fissures
• Mountain Ranges
• Volcanoes
• Rock Cycle
