Plate Motion Review

What is Earth's outer layer made of, under the surface?

• Under the land, Earth's outer layer is water. Under the ocean, Earth's outer layer is made of sand.

• Under both land and ocean, Earth's outer layer is made of hard, solid rock.

• Under the land, Earth's outer layer is made of hard, solid rock. Under the ocean, Earth's outer layer is made of sand.

• Under the land, Earth's outer layer is water.

What happens between two plates at a divergent boundary?

• New plate from the mantle fills in the gap that was created by the plates moving apart

• Sand and dirt fills in the gap that was created by plates moving apart.

• Ocean water fills in the gap that was created by the plates moving apart.

• soft solid rock from the mantle rises and hardens, adding solid rock to the edges of both plates.

What could explain how similar rock formations and fossils on different continents got so far apart?

• The continents are on different plates. The plates slowly moved apart as the soft solid rock from the mantle got added to the edges of the plates over millions of years.

• The continents are parts of different plates. The plates floated away from each other across the ocean.

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

• The continents are parts of different plates. The plates slowly moved apart as new plates from the mantle got added between them over millions of years.

At convergent boundaries...

• plates move away from each other

• plates move towards each other

• plates slide past each other

• plates are stationary

If we took a cross section of a pineapple, what would it look like?

• A

• B

If scientist where drilling down in Africa, the Pacific Ocean, and Iceland, where would they find hard, solid rock?

• Pacific Ocean, because under the ocean is hard, solid rock.

• Only Africa and Iceland, because there is hard, solid rock under land

• Africa, the Pacific Ocean and Iceland, because the entire Earth's outer layer is hard, solid rock.

• None of these areas will have hard.solid rock.

What happens at a boundary where 2 plates are moving towards each other?

• Two plates hit each other and break into pieces, creating sand.

• Two plates push into each other, causing the edges to bend upward.

• One plate goes underneath the other plate and sinks into the soft rock below.

• One plate goes under the other and sinks into the ocean.

Earthquakes and volcanoes happen...

• in random areas around the Earth.

• in similar places.

• only in California

• in the following order: volcanic activity, earthquake, volcanic activity, earthquake, and so on.

If 2 continents are getting closer to each other over time, what can you infer?

• The continents are parts of different plates. The plates were pushed towards each other earthquakes.

• The continents are parts of different plates. The plates floated towards each other on the ocean.

• The continents are parts of different plates. The plates slowly moved towards each other over millions of years. When the plates hit each other and broke into smaller pieces.

• The continents are parts of different plates. The plates slowly moved towards each other as one plates slid under the other plate into soft,solid rock over millions of years.

What is a cross section?

• a diagram that shows the parts of an objects

• a diagram that shows what the inside of something looks like.

• a physical model

• the place where 2 plates meet
