Name 2 pieces of evidence that support the theory of continental drift.
a) Rocks –ages and kinds of rocks long the edge of one continent match those rocks along another continent and trees.
b) Magnetic fields change in subduction zones and oceans connect.
c) Continents seem to fit together and hot dogs.
d) Fossil evidence – fossils of same species found on different continents, Mountain ranges –mountains on different continents

Explain how convection currents move the tectonic plates like rafts.
a) It's a scientific mystery.
b) The plates move because it's too hot to stay in one place.
c) The mantle rock heats up and rises. The mantle rock close to the surface cools and sinks. This is a convection cycle.
d) Convection currents work by physically touching the hot mantle.

Which plate boundary produces mountain formation?
a) Divergent
b) Transform
c) Convergent with subduction (Continental vs. oceanic crust)
d) Convergent (continental vs. continental crust)

Explain how a boundary would form a mountain.
a) When two plates slide past one another.
b) When two continental plates collide called a convergent plate boundary.
c) When two plate move away from each other and magma leaks up and solidifies.
d) When one plate moves underneath another.

Which plate boundary can result in a ridge formation?
a) Convergent
b) Convergent with subduction
c) Transform
d) Divergent

Explain how a ridge formation is formed.
a) The plates move apart and magma leaks up and hardens leaving behind a ridge valley.
b) When two continental plates collide called a convergent boundary.
c) When one plate moves underneath another.
d) When two plates slide past one another.

Which plate boundary can result in volcanic activity?
a) Transform
b) Convergent (continental vs. continental)
c) Convergent with subduction
d) Convergent with sublimation

Explain how a plate boundary would cause volcanic activity.
a) Plates move together, the denser oceanic crust slides underneath the continental. The crust melts into magma and pushes up.
b) The plates move apart and magma leaks up.
c) When two plates slide past one another.
d) When two continental plates collide and push rock upward.

Which plate boundary can cause earthquakes?
a) Convergent
b) Transform
c) Convergent with subduction
d) Divergent

Explain how a plate boundary can cause an earthquake?
a) By sliding past one another.
b) By moving apart from one another.
c) By colliding into each other.
d) By one going underneath the other.
