If you want to explore rock layers in regions where the rock is not exposed, you can:

• use a drill or sonography

• look for other areas that are exposed and limit your research space to ONLY areas that are visible

• wait for a fault to occur and stall your research

• use relative dating

True or False? High concentration of fossils in the Morrison Formation meant that more organisms lived there than in other parts of the country.

• True, more fossils means more organisms.

• True, the Morrison Formation is known to be the home to more species than anywhere else in the USA.

• False, it just means that the conditions there were better for fossil formation at that time.

• False, the Morrison Formation does not have any fossils.

How does knowledge of sedimentary rock formation help us to understand fossils?

• Sedimentary rock formation do not help us understand the fossils found in them.

• The rock formations help us determine absolute age of each fossil. We can tell the exact age of fossils without chemical testing.

• The rock around a fossil helps scientists with forming the theory of uniformitarianism.

• Knowing how the rock around a fossil is formed helps scientists draw conclusions about how the fossil formed and what type of environment the animal lived in.
