Examine the geologic cross section. Geologists can use different kinds of dating methods to determine the ages of rocks and rock layers. If geologists are only observing the layers as shown in the diagram (and no further lab testing is performed), which kind of dating method is being used to learn about Earth's history in this example?

• absolute dating

• radiometric dating

• relative dating

• carbon dating

A geologist is studying a geologic cross section of rock layers in a national park. The rock layers appear to be well preserved and undisturbed. Which statement best identifies the oldest rock layer in the cross section?

• The oldest rock layer is the top layer of the cross section.

• The oldest rock layer is above the bottom layer of the cross section.

• The oldest rock layer is the bottom layer of the cross section.

• The oldest rock layer is above the middle layer of the cross section.

What is the relative age of igneous intrusion W?

• Igneous intrusion W is younger than sedimentary rock layers Z and X, but its relative age to layer Y cannot be determined.

• Igneous intrusion W is younger than sedimentary rock layers Y and Z but older than layer X.

• Igneous intrusion W is older than sedimentary rock layers Z and X, but its relative age to layer Y cannot be determined.

• Igneous intrusion W is older than sedimentary rock layers Y and X but younger than layer Z.
