According to the principle of faunal succession, what must be true of the fossils on a layer below? younger than the fossils aboveolder than the fossils in the layer abovethe same age as the fossils in the layers aboveidentical to the fossils in the layers above

Option (B)

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).

sand 60

clay 10

silt 30
