Name the boundary

• convergent boundary

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

Whenever a subduction zone is formed a ______ is formed.

• Mountain
• Island Arc
• Rift
• Volcano

Plate movement is caused by ______________.

• the rotation of the Earth
• ocean tides
• convection currents in the mantle
• the moon's gravity

What are mid-ocean ridges?

• A chain of underwater waterfalls 
• A chain of underwater volcanos
• A chain of underwater mountains
• A chain of underwater rocks

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move
• The Earth is broken into lithospheric plates that move due to convection currents
• none of the above

A collision between two pieces of continental crust at a converging boundary produces a

• mid ocean ridge
• deep ocean trench
• rift valley
• mountain range
