Plate Tectonics Game Review Questions

There are three types of plate boundaries. Which choice is NOT a type of plate boundary?

• convergent
• thrust
• divergent
• transform

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

• the oceanic crust is melting.

• the denser oceanic 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 volcanoes

• diverging tectonic plates

• erosion of the land by the ocean

• converging tectonic plates

• deposition of sediments by the ocean

The Earth’s surface is not a solid surface but is divided into

• several oceanic crusts

• continental and crustal plates.

• seven continental crusts

• continental and oceanic crusts

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

The Marianas Trench, where the Pacific Plate goes under the Eurasian Plate, is the deepest sea floor in the world. These ocean trenches form when two oceanic plates collide

• the older and denser oceanic crust goes under the younger oceanic crust

• when convection currents in the mantle force the older plate downward.

• and the younger denser oceanic crust goes over the older less dense oceanic crust.

• and the plates are approximately the same age and density.

Trenches, deep underwater canyons on the sea floor are created at this type of boundary 

• Divergent
• Convergent, Subduction Zone
• Transform
