• sedimentary rock

• metamorphic rock

• igneous rock

If you know the age of a fossil, you know the relative age of the ________________ it was found inside.

• sticky tar

• rock

• amber

• ice

If you know the age of a rock, you know the relative age of the _________________ that was found inside.

• sticky tar

• fossil

• amber

• ice

Which of the following would be an example of absolute age?

• Fossil A is older than Fossil B

• Fossil A and Fossil B are the same age

• Fossil A is 10 million years old

Which of the following can be learned by using the fossil record?

• When organisms changed or evolved

• when organisms appeared on Earth

• when organisms became extinct

• All the above

By determining the age of fossils, scientists can reconstruct the history of life on Earth

• True
• False

If scientists found this fossil in a desert, what could they infer?

• what fish are like today

• that this fish lacked oxygen

• that water once covered the area where this fossil was found

Organisms D and C clearly lived in an aquatic (water) environment. Organism A does not look like it lived in the water. What is the most likely explanation for this?

• The fossil in layer A died on land and was carried to the water

• The fossils in layer C and D did not live in the same location as the fossil in layer A

• The environment changed over a long period of time. It used to be under water, but is not anymore

The millions of fossils that scientists have collected are called

• The Geologic Time Scale
• The Origin of Species
• The Fossil Record
• A really neat fossil collection

The preserved remains or evidence of ancient living things...

• clay

• fossils

• igneous rocks

• silt
