Which of the following best describes a mold fossil?

• A fossil that forms when an organism is buried and then decays, leaving an empty space in the shape of the organism.

• A fossil that forms when minerals fill in the empty space left by a decayed organism.

• A fossil that shows the footprints or burrows of an organism.

• A fossil that is made entirely of ice.

What is a cast fossil?

• A fossil that forms when an organism is preserved in amber.

• A fossil that forms when minerals fill in a mold, creating a replica of the original organism.

• A fossil that is made from the remains of plants.

• A fossil that is formed from volcanic ash.

Which of the following is an example of a trace fossil?

• A dinosaur bone.

• A shell imprint.

• A footprint or burrow.

• A petrified tree.

What does the geologic time scale represent?

• The sequence of events in Earth's history as recorded in the rock layers.

• The amount of time it takes for a fossil to form.

• The time it takes for a rock to erode.

• The lifespan of a dinosaur.
