Earth History 1

Fossil remains of a trilobite are most likely to be found in which type of rock?

• igneous
• volcanic
• sedimentary
• metamorphic

Which statement best describes the Law of Superposition?

• Each sedimentary layer of rock represents 1,000 years of Earth's age, much like the rings of a tree.
• In undisturbed layers of sedimentary rocks, the upper rock layers are older than the lower rock layers.
• In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.
• Rocks that form near volcanoes are older than surrounding rock.

Which type of fossil is formed when sediment fills an imprint that was left by an animal's body?

• amber

• cast

• mold

• trace

A fossil of a mosquito was found trapped in amber. How does this fossil compare to the original living organism?

• The fossil contains the entire body.

• the fossil has a similar outline of the body.

• The fossil is a carbon image of the organism.

• The fossil shows the activity of the organism.

What is a Geologist?

• scientist who study clouds

• scientist who study grass

• scientist who study planets

• scientist who study earth

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.
