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

Back

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

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? Options: Diagram A, Diagram B, Diagram C, Diagram D

Back

Diagram A

Front

What could explain how Glossopteris fossils in India and Australia got so far apart?

Back

India and Australia 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.

Front

Where will the team find hard, solid rock? Options: Only under 2, because Earth's outer layer is made of hard, solid rock under continents, but not under the ocean. Under 1 and 2, because Earth's entire outer layer is made of hard, solid rock. Neither under 1 nor 2, because there is water under both places.

Back

Under 1 and 2, because Earth's entire outer layer is made of hard, solid rock.

Dr. Steiner and her team have been using GPS to track two plates that are moving toward each other. Which diagram shows what is happening at the place where the plates are moving toward each other? Options: Diagram A, Diagram B, Diagram C, Diagram D

Front

Similar rock formations have been discovered in the United States and Morocco. 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?

Back

The United States and Morocco 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.

Plates collide at this type of boundary.

Scientists have discovered Mesosaurus fossils in South America and Africa. When they were living, all the Mesosaurus lived together. However, now there is an ocean between the Mesosaurus fossils. What could explain how these fossils got so far apart?

Back

South America and 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.

Scientists have been mapping earthquakes and volcanoes to find patterns. What can you tell about patterns on this map?

Back

Volcanic activity and earthquakes happened in similar areas.
