In the geologic time scale, which era is known as the "Age of Reptiles"?
B. Mesozoic
Which of the following is an example of artificial selection?
C) Breeding dogs to produce a new breed with specific desirable traits.
The fossil record is primarily found in which type of rock?
C) Sedimentary
What is the difference between relative dating and absolute dating?
Absolute dating can give the exact age of an artifact, while relative dating can only determine if one artifact is older or younger than another.
Which of the following best describes the process of adaptation?
B) A process by which a species becomes better suited to its environment over many generations.
What is the first step in the fossil formation process?
D. Burial
What is the Law of superposition and how does it relate to relative dating?
The principle that older rocks are always on the bottom and younger rocks are on the top.
"Survival of the fittest" means that:
C) Individuals that are best adapted to their environment are more likely to survive and reproduce.
Which of the following is NOT a type of fossil?
D) Synthetic resin
What are index fossils and why are they important in geology?
Fossils that are abundant, widespread, and limited to a short span of geologic time, important for correlating and dating rock layers.
What does variation within a species refer to?
C) The differences in physical traits among individuals of the same species.
Why are fossils important to scientists?
C) They help in understanding the evolutionary history of life on Earth.
What is radioactive decay and how is it used in absolute dating?
C) A process where unstable isotopes break down into stable isotopes, used to determine the age of rocks.
Why is genetic variation important for natural selection?
C) It allows for some individuals to have traits better suited to the environment, leading to evolutionary change.
Which factor does NOT contribute to the preservation of fossils?
C) High levels of oxygen
