Which layer contains the oldest fossil?

• Layer 1

• Layer 2

• Layer 3

• Layer 4

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

Which layer contains the youngest fossil?

• layer 1

• layer 2

• layer 3

• layer 4

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

In which kind of rock do we usually find a fossil?

• sedimentary rock

• metamorphic rock

• igneous rock

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 layer formed first?

• Rock Layer W
• Rock Layer X
• Rock Layer Y
• Rock Layer Z

What are the oldest fossils and why?

• B, C- because they are closest to the top

• A, B- because they are closest to the bottom

• They are all the same age- because they are all found on layer 2

• A, B- because they are found closest to the top

According to the law of superposition, which layer is the youngest?

• A
• B
• C
