How do petrified fossils form?

• An organism is trapped in ice that remains frozen for thousands of years.

• Sediment fills an organism's footprints and turns to rock.

• An organism's remains are preserved without being changed.

• Minerals soak into and completely replace an organism's remains.

The diagram below represents a stack of rock layers. These layers have not changed position since they formed. If the age of layer 4 is 400 million years and the age of layer 1 is 500 million years, then the age of Layer 2 is

• younger than 400 million years.

• 400 million years.

• older than 500 million years.

• between 400 million and 500 million years.

• Earth's entire history.

• a short interval of Earth's history.

• a long interval of Earth's history.

Which statement about the movement of Earth's crust along a fault line is true?

If scientists find an ice core from 30,000 years ago that contains chemicals radically different than the chemicals that are around today, they would likely conclude that...

• these chemicals are abundant today.

• the atmosphere 30,000 years ago was different than our atmosphere today.

• the number of layers they counted in the ice core was incorrect.

• the atmosphere never changes its composition.
