Question
The basic principle used when dating fossils that are found in sedimentary is:
- The deeper it is, the younger it is
- If it is found at the top, then it is not young
- The deeper it is, the older it is
- The layer at top is the oldest of all
Hint:
The deeper the layer, the older the fossil is deemed to be.
The correct answer is: The deeper it is, the older it is
Sedimentary rocks form by sedimentation and compaction in layers. Hence, the deeper the layer, the older the fossil is deemed to be.
Hence, (c) is the correct option.
