Plate tectonics, plate boundaries

What does the theory of Continental Drift explain?

• Ocean currents move continents around the planet

• Convection works deep within the asthenosphere

• Mid-ocean ridges force tectonic plates to move

• Continents were once together and slowly drifted to where they are today

What is the driving force behind the movement of the tectonic plates?

• Gravity

• Convection

• Wave motion

• Seismic activity

The super continent that existed when all continents were together was named

• Gondwana

• Laurasia

• Eurasia

• Pangea

What is the process of convection?

• The process of hot material rising and cooler material sinking in circular patterns

• The process of hot rock solidifying and forming new crust

• The process of explaining what goes up must come down

• Strong ocean currents moving tremendous amounts of material

Transform Boundary

• Where two plates slide past each other.

• when two plates collide

• when two plates are pulling apart

• None of the above

the region where an oceanic plate sinks down into the asthenosphere at a convergent boundary, usually between continental and oceanic plates

• subduction zone

• lava zone

• nitrogen zone

• continental zone

How do the plates move along a divergent boundary?

• They move towards one another

• They move away from one another

• They move past one another

• One move up the other moves down

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.
