    Q.

    Dinosaurs were living during Mesozoic, Triassic and Jurassic eras and eventually became extinct during the Cretaceous period. In all of these eras dinosaur fossils were found. What does this evidence tell scientists about how natural processes have changed Earth over time?

    answer choices

    Dinosaurs fossils in varying rock layers show that as the population changed they were fossilized in different rock layers by Earth’s natural processes.

    Dinosaur fossils take a long time to form and demonstrate how long the natural processes take to change the

    Earth

    Dinosaur fossils are formed within layers of sedimentary rock that were laid down by natural Earth processes which

    no longer occur today showing how Earth has changed.

    Q.

    How do these rock formations support the idea that Earth has changed due to natural processes?

    answer choices

    It has changed because of Erosion

    It has changed because of Plate Tectonics

    It has changed because of gravitational pulls of the Earth

    It has changed because of different rock layers.

    Q.

    The Law of Superposition states that

    answer choices

    the older layers of rock are at the bottom

    the older layer of rock are at the top

    the younger layer of rock is at the bottom

    the younger layer of rock is in the middle

    Q.

    If we want to figure out the age of layers from two different locations what would be the best way to do so?

    answer choices

    We can compare the fossils found in the layers of one location to the fossils in the other location

    We can use the law of superposition to figure out the rate of layer formation

    Radioactive dating to compare the age of the rocks in the layers

    Compare the number of layers in each location

    Q.

    What is relative dating?

    answer choices

    used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.

    used to determine the precise age of a fossil by using radioactive dating to measure.

    Order of layers from oldest to youngest

    Used to determine the location of the rocks around the world.

    Q.

    Is fossil creation a natural process?

    answer choices

    Yes

    No

    Sometimes

    Q.

    Why may fossil of the same organism be found on different continents?

    answer choices

    Because the continents were once together

    Similar fossils should not be found on different continents

    Because fossils change over time

    Because of the Evolution of the Earth

    Q.

    Which statement is correct

    answer choices

    Layer 2 is younger than layer 4

    Layer 1 is younger than layer 4

    Layer 2 is older than layer 1

    Layer 3 is younger than layer 1

  • Question 9

    Q.

    Which of the following statements is incorrect?

    answer choices

    Layer 4 is younger than 3

    Layer 1 is older than 3

    Layer 4 is older than 2

    Layer 2 is older than 4

  • Question 10

    Q.

    If Scientist we studying bones of animals that became igneous rock fossils. Why would they use radioactive dating to study the igneous rock?

    answer choices

    It is the easiest method to determine age

    The rate of decay in the rock provide an accurate way to calculate age.

    This method tell them the exact age of the rock which is what they are looking for .

    They would use relative dating instead.
