When two tectonic plates slide past each other, neither crashing together, nor pulling apart, the boundary between them is called...

• Divergent boundary

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 a continental plate is pulled away from another continental plate, the area of crust that is thinned and pulled apart is called.

• a trench

• a rift zone or rift valley

• ocean spreading ridge

• Continental crust

When an oceanic plate is pulled away from another oceanic plate,, magma spews from below the crust and this is formed.

• a trench

• a rift zone or rift valley

• mid ocean ridge

• continental crust

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

• Fissures
• Mountain Ranges
• Volcanoes
• Rock Cycle

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

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

• Volcano

• Mountains

• Rift

• Island Arc
