fossils have been found in the sedimentary rocks of

Alaska. These findings suggest that

A) Alaska once had a tropical marine environment

Based on studies of fossils found in the Trenton group, scientists have estimated that the climate of New York State during this part of the Ordovician Period was much warmer than the present climate. Which statement best explains this change in climate? A) The North American Continent was nearer to the Equator during the Ordovician Period. B) The Sun emitted less sunlight during the Ordovician Period. C) Earth was farther from the Sun during the Ordovician Period. D) Many huge volcanic eruptions occurred during the Ordovician Period.

17. The dots on the map below show the present locations of living coral reefs. Site X indicates an area of fossil coral reefs preserved in rocks formed during the Jurassic Period.

C) Site X has drifted southward since the Jurassic Period.

D) The coral at site X evolved from ocean-dwelling animals into land-dwelling animals after the Jurassic Period.

18. The large coal fields found in Pennsylvania provide evidence that the climate of the northeastern United States was much warmer during the Carboniferous Period. This change in climate over time is best explained by the
