The movement of tectonic plates is inferred by many scientists to be driven by

• tidal motions in the hydrosphere

• density differences in the troposphere

• convection currents in the asthenosphere

• solidification in the lithosphere

When a continental crustal plate collides with an oceanic crustal plate, the continental crust is forced to move over the oceanic crust. What is the primary reason that the continental crust stays on top of the oceanic crust?

• Continental crust is less dense.

• Continental crust deforms less easily.

• Continental crust melts at higher temperatures.

• Continental crust contains more mafic minerals.

Which feature is commonly formed at a plate boundary where oceanic crust converges with continental crust?

• a mid ocean ridge

• a transform fault

• new oceanic crust

• an ocean trench

Which evidence causes most scientists to believe that sea

floor spreading occurs at the mid-Atlantic Ridge?

• Oceanic crust is oldest at the ridge.

• Large sedimentary folds exist in the mantle near the ridge.

• Oceanic crust on both sides of the ridge is less dense than

  continental crust.

• Oceanic crust on both sides of the ridge shows matching

  patterns of reversed and normal magnetic polarity.
