Plate Tectonics

What type of event will occur at this boundary?

• Earthquake
• Volcano Eruption
• Tornado
• Mountain Building

A divergent boundary occurs when plates ....

• Pull apart
• Come together
• Slide past each other
• subducting

Where would the oldest rock be found?

• L
• M
• N
• O

Mountains are created when....

• Two continental plates collide
• Two oceanic plates pull apart
• An Oceanic plate subducts under a Continental Plate
• Two continental plates pull apart

The area where two tectonic plates meet.

• mantle
• focus
• plate boundary
• convection

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

Who was the scientist who proposed the theory of continental drift?

• Alfred Powell

• Harry Hess

• Alfred Wegener

• Ernest Rutherford

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

• Gondwana

• Laurasia

• Eurasia

• Pangea

At this boundary plates slide past one and other and earthquakes are created

• Transform

• Continental-Continental Convergent

• Divergent

• Oceanic-Continental Convergent

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
