A core sample near a fault line was drilled to learn how the area geology changed over time. The sample layers were not in the order that the scientists expected. The sample had distinct fossils in some parts of the core.

Which of these statements can the findings be used to support? Select TWO correct answers.

• A. Rock layers can be moved by fault activity.

• B. The fossils can be used to help determine the age of the rock layers.

• C. The same fossils are likely found throughout the geologic history of Earth.

• D. Rock layers are always ordered from youngest to oldest, even when near a fault line.

Which statements describe how the model is supported by fossil evidence and plate tectonics?

• • A. Lystrosaurus was a land reptile that was herbivorous

• • B. Cynognathus was unable to swim across the ocean.

• • C. Tropical ferns would not be able to survive the climate in Antarctica.

The model shows the southern continents 225 million years ago.

Which statements describe how the model is supported by fossil evidence and plate tectonics?

Select TWO correct answers.

• ***This would not allow you to choose two answers, so I split it up into two questions***

• • Lystrosaurus was a land reptile that was herbivorous.

• • Tropical ferns would not be able to survive the climate in Antarctica.

• • Fossils of the fern Glossopteris seeds were too heavy to be carried across the ocean by wind.

New discoveries have changed our understanding of Earth’s structure. Which statement describes the evidence that MOST DIRECTLY supports each explanation based on plate tectonics? Move ONE correct answer to each box. Not all answers will be used.

Scientists thought mountains formed when Earth first cooled. The revised theory suggests that mountains formed during collisions of Earth’s plates.
Evidence: 1 ​ ​ (a)  

Explanation 2: Scientists thought that Earth’s continents were always in the places they are today. The revised theory suggests that continents once formed a single supercontinent called Pangaea.
Evidence: ​ ​ (b)  

Explanation 3: Scientists thought the ocean floor had not changed since Earth formed. The revised theory suggests that new ocean floor is constantly forming and spreading outward.
Evidence: Ocean floor near mid-ocean ridges is younger than it is farther away.

• A. Mountains vary with age.
• C. Some continents appear to fit like puzzles
• Mountains wear away over time

The diagram shows a cross-section of layers.

Descriptions of superposition are listed. Which statements describe the different evidence for a change due to superposition?

• C surface is flat and covered in a layer

• When the limestone layer was deposited, this region was located in a shallow sea.

• B. Plates that make Earth’s surface move

• The rock layers are folded where two continents collided.

• A. limestone forms in warm, shallow seas

• The rocks were uplifted, eroded, and weathered.

This graph models the ages of rock in an ocean floor in millions of years ago (Ma).

Which statement describes the evidence for plate tectonics based on the data in the model?Which statement describes the evidence for plate tectonics based on the data in the model?

• The data show that continents are sliding across the ocean floor.

• The data show that continents move by pushing through the ocean floor.

• The data show that continents move as the sizes and shapes of the ocean floor change.

The North American plate is moving away from the Eurasian plate. The diagram describes this process in Iceland.

Which statement describes what plate tectonics is LIKELY to cause based on the theory of plate tectonics?

• • Sea levels will rise, eroding the coastline near the ridge.

• • Seawater will erode the land underneath the ridge, creating caves.

• • Volcanic activity will shape the land along the ridge through plate fissures.

• Plate movement will cause tsunamis to flood and erode the coastline near the ridge.
