When a rock formed, it contained the parent isotope, uranium-238, but did not contain the daughter isotope. How would this rock change over time?

• Amount of uranium-238 would increase, and the amount of lead -206 would decrease

• The amount of uranium-238 would decrease, and the amount of lead-206 would increase

• The amount of uranium-238 would stay the same, and the amount of lead-206 would increase

• The amount of uranium-238 would decrease, and the amount of lead-206 would stay the same.

a team geologist compared the rock layers found in Florida to those found in northwest Africa. They placed a the rock layers from the two regions in order from youngest to oldest.What did the team make?

• A fossil record

• A geologic record

• A geologic column

• A topographic map

Which Property of fossils allows scientists to determine the relative age of rock layers?

• Fossils can show change over time as species evolve

• Fossils form the remains of living organisms

• What are usually found only in sedimentary rock

• Fossils can be analyzed to determine the exact ages

Thousands of fish fossils discovered high in the Rocky Mountains MOST likely indicate that

• ancient sea levels were once high enough to cover the mountains.

• a large flood washed the fish up to the tops of the mountains.

• the mountains were once part of the sea floor that was pushed up by tectonic forces.

• the fish were inhabitants of an ancient stream that became frozen during the ice ages.

Imprints of the shells of ocean clams are often found in the rocks of the Appalachian Mountains. What is most likely indicated by these imprint fossils?

• Mountain river clams evolved from ocean clams.

• Ocean clams evolved from mountain river clams.

• These mountains once had a more rainy climate.

• These mountains were once under the ocean.

• the tectonic plate under Africa was closer to the South Pole at one time

• the equator was not always where it is currently located

• volcanoes did not exist until after faults occurred in Earth’s crust

• the location of the North Pole and the South Pole changed

Fossilized teeth from an extinct shark were found embedded in a rock layer at the base of a mountain, several hundred kilometers (km) from the nearest ocean.  Which of the following statements best explains why the rock layer cannot be igneous rock?

• The melting process would have destroyed the fossil.

• Weathering and erosion would have broken up the fossil.

• The rock was found at an inland location away from heat and pressure.

• Repeated volcanic eruptions would have buried the fossil too deeply to be found.

Antarctica is the coldest, driest continent on Earth, and only a few species survive its harsh elements. Yet scientists have found fossils of green fern plants in Antarctica. Based on these findings, which of these is the best conclusion?

• The climate of Antarctica changed over time.

• The location of Antarctica has always been at the South Pole.

• These fossils are of an organism that adapted in Antarctica over time.

• This species could currently exist in Antarctica if there was less competition.
