Multiple Choice

What is permineralization?

• The pressure from above layers of rock form casts of previously living things

• The process of fossilization where the organic matter of a previously living creature is replaced with minerals through the formation of sedimentary rock

• The process of fossilization where an insect gets trapped in hardened tree sap

Multiple Choice

What is Amber?

• The process of fossilization where the organic matter of a previously living creature is replaced with minerals through the formation of sedimentary rock

• The pressure from above layers of rock form casts of previously living things

• The process of fossilization where an insect gets trapped in hardened tree sap

Multiple Choice

• compression

• cast

• amber

• compression

Multiple Choice

A fossil that is the product of heavy pressure leaving dark marks as a fossil is called...

• amber

• cast

• mold

• compression

Multiple Choice

Which is NOT a reason fossils are so rare?

• Organisms, like jellyfish, with soft parts are least likely to become fossilized

• Many organic materials, included bones, may be broken down through other naturally occurring processes.

• The remains of many organisms are consumed

• All of the above

Multiple Choice

A paleontologist just discovered a Flower fossil. In which layer do you think the fossil was found in?

• Cenozoic Layer

• Mesozoic Layer

• Paleozoic Layer

• Late Proterozoic Layer

Multiple Choice

Geologists studied fossils taken from the top of a mountain. The chart lists several fossils taken from this location as well as their original habitat.What can be concluded based on the fossil evidence?

• The mountain climate was once much warmer than it is today.
• The mountain climate was once much colder than it is today.
• The mountain was covered by water at some point in the past.
• The elevation in the area was much higher at some point in the past.
  

Multiple Choice

Which statement is true?

• The oldest layers of rock and soil are closest to the surface of the earth

• The youngest layers of rock and soil are farther away from the surface of the earth.

• inclusions are younger than the layers they are found in

• Absolute dating and relative dating are two methods used by scientists to determine the age and sequence of geologic events.

Multiple Choice

According to the law of superposition, the oldest fossils are found

• At the top of the rock layers

• Near the bottom of the rock layers

• In the middle of the rock layers

• Somewhat near the surface

Multiple Choice

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.

Multiple Choice

What role do faults play in the Law of Superposition?

• Faults create new types of rock.

• Faults are younger than the layers they cut through.

• Faults are the same age as the layers they cut through.

• Faults are older than the layers they cut through.

Multiple Choice

The diagram shows different layers of sedimentary rock. Each layer is labeled with a letter.

• The left part of Layer B is younger than the right part.

• The left part of Layer F is the same age as Layer M.

• Layer R is older than Layer M

• Layer I is older than Layer B

Multiple Choice

• Archean

• Proterozoic

• Phanerozoic

Multiple Choice

What are the 4 Eons in order?

• Hadean, Proterozoic, Archean, Phanerozoic

• Hadean, Archean, Proterozoic, Phanerozoic

• Archean, Hadean, Proterozoic, Present

• Hadean, Archean, Proterozoic, Mealrozoic

Multiple Choice

What was the effect of "The Great Dying"?

• If allowed plants to thrive.

• Almost all organisms perished, which started the evolution of dinosaurs.

• All organisms could now walk on land and swim in water.

• Water was now more affordable for organisms in any area.

Multiple Select

What 2 pieces of evidence is most helpful in understanding events that occurred in Earth’s past?

• Layers of Rock

• Scientific Tools

Multiple Choice

How are periods, eras, and eons related?

• Periods are the building blocks of all time. Two or more periods form an era. Two or more eras form a eon.

• Eras are the building blocks of all time. Two or more eras form an eon. Two or more eons form a period.

• Eons are the building blocks of all time. Two or more eons form a era. Two or more eras form an period.

Multiple Choice
