• Diagram D

Fossil remains of Lystrosaurus have been found 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 fossils. What could explain how these fossils got so far apart?

• 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 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 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.

Where will geologists be able to 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.

Patterns on this map tell us that...

• Volcanic activity and earthquakes can cause damage to buildings and hurt people.

• Volcanic activity and earthquakes happened in similar areas.

• Volcanic activity and earthquakes happened in random locations all over the map.

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

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

• Argentina 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.

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

• Argentina & South Africa are parts of differetn 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.

• Argentina 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 engineers wants to study hard, solid rock under the surface of Earth. The team is considering drilling down in the Indian Ocean (1) and in Sri Lanka (2). Where will the team find hard, solid rock?

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

• only under 2, because Earth's outer layer is made of hard, solid rock underneath continents but not under the ocean

• Neither 1 nor 2, because there is water underneath both places

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