In the late 1700s scientists proposed that the layers in the rocks of mountains and canyons represented a record of the passage of time, with the younger layers lying on top of the older layers. What could they determine about the fossils they were finding in the rocks based on this observation?
A. Fossils in upper layers were younger than fossils in lower layers.
B. Fossils in upper layers were less weathered and more detailed than those in lower layers.
C. The exact age of a fossil could be determined by counting the rock layers.
D. The oldest fossils were the same as the ones found in younger rock layers.

One thing scientists in the late 1700s could determine about the fossils they were finding were fossils in the upper layers were younger than fossils in lower layers. The correct answer is A.

The fossils of the upper layers of the rocks are much younger than the lower older layers.

What can be determined on the basis of layers of rocks. ?

late 1700's scientists had proposed the layers of the rocks in the rocks of the mountains and the canyons are represented by the record of the passage of time as by the older under the younger rocks that helped to determine the level of the rocks. Thus based on the observations.

As a matter of fact, the younger layers are those that get deposited at the top and they are represented by the younger deposits of the soil, sand, clay, etc.

The older layers are a representation of the decomposition and the consolidation of rocks and thus consists of the fossil remains. Thus the answer A is correct.
