  • Question 1
    20 seconds
    Q.

    Which process would be most effective in determining the age of fossils embedded in rock?

    answer choices

    relative dating

    absolute dating

    use of index fossils

    use of core sampling

  • Question 2
    30 seconds
    Q.

    Which statement is true?

    answer choices

    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.

  • Question 3
    20 seconds
    Q.

    What role do faults play in the Law of Superposition?

    answer choices

    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.

  • Question 4
    30 seconds
    Q.

    Which statement best describes the Law of Superposition?

    answer choices

    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.

  • Question 5
    20 seconds
    Q. According to the law of superposition, which layer is the youngest?
    answer choices
    A
    B
    C
  • Question 6
    20 seconds
    Q. The Law of Superposition helps scientists to determine what?
    answer choices
    The absolute age of rock layers
    The age of fossils
    The relative age of rock layers
    the super powers of rocks
  • Question 7
    20 seconds
    Q.

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

    answer choices

    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

  • Question 8
    20 seconds

    A scientist who studies ancient life/fossils is a:

    answer choices

    Paleontologist

    Archaeologist

    Biologist

    Sociologist

  • Question 9
    20 seconds
    Q.

    The age of a rock compared to other rocks around it is:

    answer choices

    Superposition

    Absolute age

    radioactive decay

    relative age

  • Question 10
    20 seconds
    Q.

    According to the diagram, what is the most recent event?

    answer choices

    B

    I

    R

    H

  • Question 11
    30 seconds
    Q.

    The diagram shows a section of land that has been undisturbed and includes a fossil.What can be concluded about the fossil?

    answer choices

    The fossil is younger than the limestone.

    The fossil is older than the shale.

    The fossil is approximately the same age as the limestone.

    It is approximately the same age as the sandstone.

  • Question 12
    30 seconds
    Q. The diagram shows layers of rock that have been disturbed.Which layer of rock is the oldest?
    answer choices
    Layer A because other layers were formed in it.
    Layer B because it is under layers C and D.
    Layer D because it is the least eroded.
    Layer F because it is on the top.
  • Question 13
    30 seconds
    Q. 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?
    answer choices
    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.
  • Question 14
    30 seconds

    3, 5, 4, 2, 1

    5, 4, 3, 2, 1
