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

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

What does the Law of Superposition tell us?

• The most superior rock is the top layer of rock

• The oldest rock is the most top layer of rock

• The youngest rock is the most top layer of rock

• The strongest rock is the most top layer of rock
