Geologic History Test Review

The diagram below shows fossils and rock features.

How does intrusion X compare to the ages of the other rock layers and fossils in this geologic column?

• Intrusion X is older than layers Y and Z.

• Intrusion X is younger than all the layers.

• Intrusion X is older than the clam and broadleaf fossils.

• Intrusion X is younger than the broadleaf and fern fossils.

Scientists can use relative dating, absolute dating, or a combination of the two techniques to determine the age of a fossil. Which of the following could be determined using both methods?

• the difference in age between two fossils
• which of two fossils is the older
• a narrow age range for a fossil
• the exact age of a fossil

The diagram shows different layers of sedimentary rock. Each layer is labeled with a letter. Which statement correctly describes the relative ages of the rock layers shown in the diagram?

• The left part of Layer B is younger than the right part.

• The left part of Layer F is the same age as Layer M.

• Layer R is older than Layer M.

• Layer I is older than Layer B.
