Looking at these two fossil cores from different continents, which two layers are of approximately the same age? How do you know?

• A and D - both at the top

• B and E - neither have fossils evidence

• C and D - have the same fossil evidence

• C and F - the rock pattern looks the most similar

How could scientists use core samples of fossils to study extinct organisms?

• They could determine relative age of an extinct organism

• They could determine how the organism went extinct

• The could determine the color of the organisms fur

• The could determine how the organism sounded

Why do you think there are not fossil for every organism that has every lived?

• Many organisms decompose too quickly to become fossils

• They do, the fossils are just destroyed

• Some plants and animals do not have carbon in them

• Many organisms are too large to form fossils

Which of the following terms is the science of dating materials, like rocks, based on how much of a radioactive element it contains today.

• Radiometric dating

• Stratigraphy

• Geology

• Fossilography

In which layer did fossil C come into existence? How do you know this?

• Layer 1-Because that is the layer it is first seen

• Layer 1- Because that is the last layer it is seen in

• Layer 2- Because that is the layer it is first seen

• Layer 2- Because that is the last layer it is seen in

Fossil A is an ancient mollusk, an organism that needs water to survive. Why do you think that the mollusk went extinct in this particular sample of the fossil record?

• When the ocean levels rose in layer 4, the mollusk went extinct because they cannot live in water

• For some reason, the ocean disappeared causing the mollusk to thrive

• For some reason, the ocean disappeared causing the mollusk to go extinct

• When the ocean level rose in layer 4, the mollusk thrived because they need water

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
