Which conclusion does this diagram BEST support?

• Both organisms lived at the same time because the fossils they formed were found in rock layers of about the same depth.

• Organism Y lived before Organism X because Organism Y was found in an older rock layer.

• The fault formed while Organism X was living and after Organism Y had died because the fault is located between the two fossils.

• The earthquake that caused the fault most likely killed both organisms because the fossils formed during the time of the earthquake.

Use the map to answer the question that follows.

Why would the state of Kansas have vast deposits of marine fossils, when the state is located so far from any ocean?

• Many organisms that live in the ocean must have once lived in Kansas.

• Groundwater must have carried the fossils to Kansas from locations far away.

• Animals that fed on ocean organisms must have carried them to Kansas.

• Seawater must have covered Kansas at some time in the past.

The pictures below show some fossils of shellfish that were found in a rock layer on a mountainside.

What is the most likely reason they were found in the rock layer?

• Shellfish lived on dry land long ago

• Fossils last longer when they form a mountain.

• People left the shells on the mountainside.

• The rock layer was once part of the sea floor.
