Question

read the passage and answer the following question(s).
fossils in rock strata
scientists are investigating rock formations at two different locations. the scientists find different fossils in the layers at each location. the scientists have labeled each rock layer with a letter. the rock layers are shown.
what can scientists learn by comparing the positions of the rock layers of the two locations?
a. they can predict future natural disasters that will affect life in the region.
b. they can predict the how organisms in the region will change in the future.
c. they can learn the specific date that each rock layer formed
d. they can learn the relative time that each rock layer formed

Explanation:

• Option A: Comparing rock layers doesn't predict future natural disasters.
• Option B: Rock layers don't show future organism changes.
• Option C: Rock layers don't give specific formation dates.
• Option D: By comparing rock - layer positions, scientists can learn the relative time of formation (lower layers are usually older).

Answer:

D. They can learn the relative time that each rock layer formed
