What can you conclude about fossil by looking at the layers of rock? a. the exact age of the fossil b. the fossils in the lower layers are older than the fossils in the upper layers. c. there is no difference in age between the different layers of rock d. the fossils in the upper layers are the ancestors of the fossils in the lower layers.

The correct answer is option B.

Explanation:

The layers of the rocks also known as the geological column. By studying the rock layers the scientists have come to know that the rocks are arranged in layers and comprise fossils. Of these the fossils, which are the oldest are found at the deepest layers, and the most recent ones or the youngest fossils are found close to the top. Thus, one can consider the layers of rocks as a vertical timeline.
