Why does continental crust slide over oceanic crust, causing subduction, at convergent boundaries?

• Oceanic Crust is more dense

• Continental Crust is more dense

• Oceanic crust is less dense

• Continental crust is just better!

Which boundary type involves plates sliding horizontally past each other?

• Transform boundaries

• Plate boundary zones

• Divergent boundaries

• Convergent boundaries

What is the primary method used to track current plate movement?

• Tide gauges

• Seismographs

• Weather satellites

• GPS
