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.
