Question

According to the principle of faunal succession, what must be true of the fossils on a layer below?

younger than the fossils above

older than the fossils in the layer above

the same age as the fossils in the layers above

identical to the fossils in the layers above

Answer 1

The answer to this is older, but it's not a proven fact even though schools teach it as if it were. It is still just a theory if you think about it with how much the earth moves, areas of rock could be complete upside down and no one would know, it would be like history in reverse.

Answer 2

Option (B)

Step-by-step explanation:

According to the principle of faunal succession, the fossilized plants and animals are deposited in the layers of sedimentary rocks in a vertical manner succeeding one another and they are very distinct, dependable and easily recognized over a broad horizontal distances.

The fossils that are found at the bottom layer is the oldest fossil which have deposited in the ancient time. And the fossils that are present at the top are the youngest fossils and are of geologically very recent.

Thus, the correct answer is option (B).
