HISTORY OF THE EARTH UNIT REVIEW

A fossil found in a surface rock layer is of the same species as a fossil found in a deeper rock layer. However, the two fossils differ slightly in structure. What do differences in the structures of the fossils indicate?

• there are no differences between the two species

• the life span of the species changed

• the species changed over time (evolved)

• the species had many predators

What is the best way to measure the age of a solid planet?

• Study maps of the world and look for the tallest mountains.

• Look at the fossils in rocks to get the exact age of the Earth.

• Test the rate of decay of elements found in igneous rocks.

• Count the rocks in the forest.

Just north of Orlando, there is a lot of farmland. There are also fossil dig sites. At these sites, fossils of ancient horses and pigs can be found. Sharks teeth and other marine fossils can also be found. Which of the following best explains how that is possible?

• The marine animals learned to walk on land.

• People dropped them there when they no longer wanted them.

• The area used to be under water.

• Birds dropped the bones there after they were finished eating the animal.

How is a law different from a theory?

• A law is an explanation that tells what is happening.

• A law is an observable fact that describes what is happening.

• A law is an explanation that explains why something is happening.

The image on the left follows the Law of Horizontality. The image on the right shows tilting that occurred after the layers were deposited. What is the oldest layer in the image on the right (the tilted layers)?

• Layer A

• Layer B

• Layer C

Which of the following is LEAST likely to help you determine the age of sedimentary rocks?

• Analyze seismic data to determine when radioactive isotopes break down into stable isotopes.

• Look for index fossils in the rock layers.

• Apply absolute dating methods to determine the amount of decay of radioactive isotopes that might be found inside the sedimentary rocks.
