Checkpoint: Determine the sequence of events in Earth’s history at different locations, based on the rock layers you observe:

For each location, order the geologic events that happened from oldest to youngest.  

Provide the piece of evidence that supports your order.

Use the diagram below to answer the following question. 

Other than the fact that shale is on top of the granite intrusion, provide a piece of evidence that explains how we know that the layer of shale formed after the granite intrusion.

Base your answer on the geologic cross section below. The rock layers have not been overturned. Point A is located in the zone of contact metamorphism



Which geologic event is the youngest: the basalt intrusion or the fault line?

How can we justify the fact that breccia is NOT the youngest feature?

Fill in the Blanks

Multiple Choice

The cross section below represents the bedrock structure of a section of Earth's crust. Letters A through H represent rock units. Line XY represents a fault. The rock layers have not been overturned.

When did faulting along line XY occur?

• after the intrusion of rock unit A

• after the deposition of rock units B, C, and D

• after the formation of rock units E and F

• before the formation of rock units G and H

Multiple Choice

The cross section below represents the bedrock structure of a section of Earth's crust. Letters A through H represent rock units. Line XY represents a fault. The rock layers have not been overturned.

When did faulting along line XY occur?

• after the intrusion of rock unit A

• after the deposition of rock units B, C, and D

• after the formation of rock units E and F

• before the formation of rock units G and H

Multiple Choice

The cross section represents rock units that have not been overturned. Lines CC' and GG' represent unconformities. The geologic ages of some of the lettered rock units are shown below the cross section

• A

• F

• L

• M

Multiple Choice

Why is there no contact metamorphism indicated between rock unit L and rock unit F?

• Conglomerate does not metamorphose.

• The intrusion was not hot enough to metamorphose rock unit F.

• The contact metamorphism within rock unit F eroded away.

• Rock unit F was deposited after the intrusion of rock unit L.

Multiple Choice

Which inference about rock units D, E, and H can best be supported by evidence in the cross section?

• They contain mostly sand-sized sediment.

• They contain both land and marine fossils.

• They were altered by contact metamorphism.

• They were deposited as horizontal layers and were later tilted.
