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.
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.
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.
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.
