What could the relative age of two rocks tell you about them?

a. One rock is 10,000 years old, and the other is 8,000 years old.
b. One rock is older than the other.
c. They both have fossils in them.
d. One rock is closer to the surface than the other.

What would a geologist do if he/she wanted to determine the age of rock layers at a given location using relative age?

a. Find some information on the approximate age of local landforms.
b. Find the relative age of one rock at the given location.
c. Find the relative and absolute ages of all rock layers at that location.
d. Find a fossil in a sedimentary rock layer nearby.

How does folding change rock layers?

a. Folding can alter the composition of rock layers.
b. Folding can change the position in which rock layers appear.
c. Folding always moves younger rock layers to the surface.
d. Folding does not change rock layers.

Sometimes, layers of rock are overturned so frequently that the youngest rock layer may appear at the bottom, which is reverse of what is ordinarily expected.

a. True
b. False

My answers: b, b, b, a

They're all correct!

b B B A are the correct answers

For the question: "What could the relative age of two rocks tell you about them?", your answers are correct. The relative age of two rocks can provide information about their order of formation or which rock is older or younger.

For the question: "What would a geologist do if he/she wanted to determine the age of rock layers at a given location using relative age?", your answer is incorrect. The correct answer is c. When determining the relative age of rock layers, a geologist would ideally find the relative and absolute ages of all rock layers at that location to establish a comprehensive understanding of their chronological sequence.

For the question: "How does folding change rock layers?", your answer is incorrect. The correct answer is b. Folding can change the position in which rock layers appear. When rocks are folded, their original horizontal orientation gets distorted, creating folds where the layers can become inclined, curved, or even overturned. This alteration in position can affect the overall appearance and arrangement of the rock layers.

For the statement: "Sometimes, layers of rock are overturned so frequently that the youngest rock layer may appear at the bottom, which is reverse of what is ordinarily expected.", the correct answer is a. True. Although it is more common for layers of rock to be arranged with the oldest layers at the bottom and the youngest layers at the top (in a concept known as the Law of Superposition), certain geological processes or tectonic forces can cause the inversion or overturning of rock layers, resulting in the youngest layer appearing at the bottom.
