Plate Motion- Review

Which statement best describes what Earth’s outer layer is like underneath the surface in the image?

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

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

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

.Fossil remains of Lystrosaurus (an extinct four-legged animal) have been discovered in India and South Africa. When they were living, all the Lystrosaurus lived together on land, and they could not swim. However, now there is an ocean between the Lystrosaurus fossils. What could explain how these fossils got so far apart?

• India and South Africa 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.

• India and South Africa are parts of different plates. The plates floated away from each other across the ocean.

• India and South Africa are parts of different plates. The plates slowly moved apart as new plates from underneath got added between them over millions of years.

• India and South Africa 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 Saudi Arabia (1) or in the Arabian Sea (2). Where will the geologists find hard, solid rock?

• neither under 1 nor 2, because there is sand and gravel under both places

• neither under 1 nor 2, because there is water under both places

• under 1 and 2, because Earth’s entire outer layer is made of hard, solid rock

• only under 1, because Earth’s outer layer is made of hard, solid rock under continents but not under the ocean

Similar rock formations have been discovered in Brazil and South Africa. These rock formations were formed at the same time and are made of the same types of rocks. What could explain how these rocks got so far apart?

• Brazil and South Africa 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.

• Brazil and South Africa are parts of different plates. The plates floated away from each other across the ocean.

• Brazil and South Africa are parts of different plates. The plates slowly moved apart as new plates from underneath got added between them over millions of years.

• Brazil and South Africa 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.
