Plate Motion Quiz Review

Which statement best describes Earth’s outer layer underneath the surface of the Earth?

• Underneath the soil, Earth’s outer layer is made of water.

• Underneath both the soil and the ocean, Earth’s outer layer is made of sand and water.

• Underneath the soil, Earth’s outer layer is made of hard, solid rock. Underneath the ocean, Earth’s outer layer is made of sand.

• Underneath both the soil and the ocean, Earth’s outer layer is made of hard, solid rock.

Fossil remains of ammonite (an extinct shelled animal like a snail) have been discovered in Australia and North America. When they were living, all the ammonite were located together in the same region, but now the ammonite fossils are separated by continents. What could explain how these fossils got so far apart?

• Australia and North America are parts of different plates. The plates slowly moved apart as new plates from underneath got added between them over millions of years.

• Australia and North America are parts of different plates. The plates slowly moved far apart as soft, solid rock from underneath got added to the edges of the plates over millions of years.

• Australia and North America are parts of different plates. The plates floated away from each other across the ocean.

• Australia and North America are parts of different plates. The plates were sometimes pushed far apart by earthquakes, and soft, solid rock from underneath got added to the edges of the plates.

A team of geologists wants to study hard, solid rock under the surface of Earth. The team is considering drilling down in the North Pacific Ocean and in Timbuktu. Where will the team find hard, solid rock?

• Only under Timbuktu, because Earth’s outer layer is made of hard, solid rock under continents but not under the ocean.

• Both places because Earth’s entire outer layer is made of hard, solid rock.

• Neither because there is water under both places.

• Neither because there is sand and gravel under both places.

Dr. Choi and his team of geologists have been studying GPS data that shows that two plates moved apart. Which diagram shows what happened between the two plates as they moved away from each other?

• Diagram A: Soft, solid rock from underneath the plates rose and hardened, adding solid rock to the edges of both plates.

• Diagram B: Sand and dirt filled in the gap that was created by the plates moving apart.

• Diagram C: Ocean water filled in the gap that was created by the plates moving apart.

• Diagram D: A new plate from underneath filled in the gap that was created by the plates moving apart.

At convergent plate boundaries, continents would crash into each other.

• True since the plates are moving together.

• False since one plate is subducting that continent would move downward
