SC.7.E.6.4

Scientists find a fossil of a fish on top of a mountain. What kind of evidence does the fossil provide scientists about the way this area might have changed over time?

a. It shows that fish were once able to live without water.

b. It shows that oceans can change quickly and become land.

c. It shows that the animals found on the mountain today evolved from fish.

d. It shows that the mountain may have once been under water and raised up by natural

processes.

Fossils are the preserved remains of organisms that lived long ago. According to the law of superposition, the rock layers that contain fossils should be far below Earth’s surface. Which answer best explains why fossils are sometimes found at or near the surface?

a. Fossils are less dense than rock, so they rise to the surface.

b. Fossils are moved to the surface by other organisms.

c. Sedimentary rock layers are relatively soft, and new fossils sink through upper layers

into older, deeper layers.

d. Some rock layers with fossils have been exposed because of different processes, such as faulting, folding, and weathering.
