Evidence of Earth's Geologic History (7.E 6.3 and 6.4)

Nathan is given an image showing three rock layers and an intrusion of basalt. He is asked to determine the order in which these layers were formed. Nathan already knows that when molten rock pushes its way into rock layers already formed, it creates an intrusion. A diagram is provided. Which of the following indicates when the basaltic intrusion must have occurred?

• After the limestone was deposited

• Before the granite was formed

• After the sandstone was deposited

• Before all three layers were formed

• Radioactive dating

• The law of superposition

• Earthquake location

The decay of uranium isotopes is used to provide what information about Earth's history?

• The absolute age of rocks

• Changes in climate over time

• The diet of ancient animals

Mrs. Jones provides her class with an image that shows rock layers in their original order along with a fracture in some rock layers caused by an earthquake. She has asked students what information can be determined from these rock layers. An image is provided. Based on the evidence in the illustration, when did the earthquake occur?

• Before Layer W was deposited

• Before Layer X was deposited

• After Layer Y was deposited

• After Layer Z was deposited

What evidence supports the scientific theory that continents on Earth were at one time a part of a large supercontinent called Pangaea before they drifted apart?

• Sediments found along the coasts of continents often were transported there by wind or moving water.

• The plants and animals that live on the same continent can often look very different from their fossil ancestors.

• The fossils of some kind of organisms can only be found in one location on Earth.

• In several locations, the shape of one continent matches the shape of a nearby continent, like puzzle pieces.

The distribution of fossils is used as evidence for plate tectonics. The distribution of four different fossil organisms over three different continents is shown in the provided diagram. The distribution of which organisms can be used as evidence that Africa was once connected to South America?

• Lystrosaurus, Mesosaurus, and Glossopteris

• Cynognathus, Glossopteris, and Lystrosaurus

• Glossopteris, Cynognathus, and Mesosaurus

• Cynognathus, Mesosaurus, Lystrosaurus

Scientists use several processes to determine the age of rock layers and fossils on Earth. Which process can be used for the absolute dating of fossils?

• Relative dating

• Radioactive dating

• The law of superposition

• Earthquake location

When looking at the shape of the continental shelves that surround South America and Africa, it can be observed that the continental shelves fit together. An image is provided. Which of the following ideas best supports this observation?

• The continental shelves of these two continents are made of the same type of rock material.

• The tectonic plates between these continents are roughly the same age.

• These continents were joined in the past and have moved apart since that time.

• The material that makes up the continental shelves is eroded from the continents.

Stratigraphy is the study of rock layers and layering. An image of a various sedimentary rock layer is provided. In which of the labeled sections of the sedimentary rock layers would the oldest rock be on top of the younger rocks?

• Area A

• Area B

• Area C

• Area D

Examining rocks that form on either side of the Mid-Atlantic Ridge provides evidence that supports the theory of plate tectonics. An image is provided. These rocks provide evidence of plate movement because as we look at rocks farther and farther from the ridge, which of the following is occurring?

• The iron content is increasing.

• Their particles are getting smaller.

• They become thicker and thicker.

• They are consistently older.
