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
Answer number one is B
B,B,B,A is correct i just took the test
I just took the test too. Anonymous is correct.
B,B,B,A is the correct answers
Your answers for the first three questions are incorrect. Here are the correct answers along with explanations:
1. What could the relative age of two rocks tell you about them?
Correct answer: b. One rock is older than the other.
Explanation: The relative age of two rocks tells us the order in which they were formed, indicating which rock is older and which is younger. It does not give us specific numeric ages or information about fossils or their depth within the Earth.
2. What would a geologist do if he/she wanted to determine the age of rock layers at a given location using relative age?
Correct answer: c. Find the relative and absolute ages of all rock layers at that location.
Explanation: Geologists use relative age dating to determine the relative order of rock layers, but to assign actual ages to those layers, they need additional information. By comparing the rock layers to known age benchmarks (such as fossils or other dated rocks), they can determine both the relative and absolute ages of the rock layers at a given location.
3. How does folding change rock layers?
Correct answer: b. Folding can change the position in which rock layers appear.
Explanation: Folding refers to the bending or deformation of rock layers due to tectonic forces. This process can change the position of rock layers, causing them to appear tilted, folded, or even completely overturned. However, folding does not alter the composition of rock layers themselves.
4. 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.
Correct answer: a. True
Explanation: The statement is indeed true. Through processes like tectonic activity or erosion, rock layers can be overturned and appear in a reverse order compared to their original formation. This phenomenon is known as overturned or overturned stratigraphy. It is unusual but can occur in certain geological settings.
