stich3 [128]

Answer:

Option C.

Scientist explain the incomplete fossil record because not all organisms become fossils. Processes like erosion and mountain building can change rock layers, causing fossils to be spread over multiple layers or destroyed.

Explanation:

  • Fossils are the remains of organisms that are found on the rocks after they die.
  • So, no one can be 100% sure about the complete fossil record because of the continuous process like erosion and other natural calamities.
  • The sediment must cover any organism's remains to start the fossilization process to start. Most of the organisms start decomposing  before this process can be executed.
