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

The plate boundary located off the western coast of South America is most likely an area of

• subduction because the plates are colliding.

• folded mountains because the plates are colliding.

• mid-ocean ridges because the plates are pulling apart.

• ocean-floor spreading because the plates are spreading apart.

What was the main reason Wegener’s continental drift hypothesis was rejected?

• A reason for the motion of the continents could not be explained.

• He did not propose any mechanisms.

• His proposed mechanisms were physically impossible

Observe this diagram of a plate boundary. One statement BEST describes what is happening. It is that

• the oceanic crust is melting.

• the denser ceanic crust is subducting under the less dense oceanic crust

• volcanic islands are forming.

• the tectonic plates are moving away from each other.

What geological forces might be responsible for this range of mountains?

• diverging tectonic plates

• erosion of the land by the ocean

• converging tectonic plates

• deposition of sediments by the ocean

Where would sea floor spreading most likely occur?

• At convergent boundaries (oceanic vs. oceanic)

• At convergent boundaries (oceanic vs. continental)

• At divergent plate boundaries (oceanic vs. oceanic)

• At transform plate boundaries
