Amplify Science Plate Motion Chapter 2.1-2.3

How do the tectonic plates move?

• They move by being pushed around by earthquakes along the plate boundaries.

• They move by gliding around on hard, solid rock, called the mantle.

• They move by volcanic eruptions that occur along the plate boundaries.

• They move by gliding around on top of soft, solid rock called the mantle.

When two plates are moving away from each other, they are...

• separating, while leaving a gap.

• diverging.

• converging.

• nothing since plates don't move.

Which piece of evidence best supports the following claim the best? "Earthquakes are a result of plate tectonic movement"

• an earthquake is monitored along a plate boundary where the two plates are known to be converging

• an earthquake causes a tsunami to hit an island off the coast of a large country

• a volcanic eruption occurred right after an earthquake along a plate border

• an earthquake occurred and then two plates were monitored and observed to diverge quicker than normal

If a scuba diver were to dive down in the ocean to a divergent plate boundary, what would he expect to see?

• a mid-ocean ridge

• a gap that exposed the mantle

• a trench

• the plates breaking into pieces as they move closer to each other

What kind of rock is the outer layer made of underneath the ocean?

• it is made of soft, solid rock

• it is made of hard, solid rock

• it is made of loose sediments because of the water above

• is is made of sand and clay all the way down to the mantle

What would you expect to a convergent plate boundary?

• The two plates separating, resulting in a gap between the plates.

• a trench

• a mid-ocean ridge

• the mantle rising up from the crack
