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 is an example of relative age

• Fossil A is older than Fossil B

• Fossil A is about 10 million years old

• Fossil B is 2 million years old

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
