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

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

Why does the oceanic crust subduct (move under) the continental crust?

• Because it is MORE DENSE than the continental crust

• Because it is OLDER than the continental crust.

• Because it is THICKER than continental crust.
