It is believed that during the late Cretaceous period sea levels rose drastically resulting in about a third of the Earth's present land masses being underwater. Which of the following types of evidence supports this theory?
A. minerals and oil found in underground deposits
B. corals and marine fossils found in the Great Plains
C. volcanoes and igneous rocks found on the ocean floor
D. dinosaur and bird fossils found in swamp areas

The answer is C

An understanding of fossil evidence of sea level changes is needed to answer this question. Fossils of corals and other marine organisms indicate that a particular area was once covered by a sea. Finding these fossils in land that is no longer underwater, such as the Great Plains, provides evidence that the seas have changed substantially over time.
