Question

If the fossil of an organism is found in deep layers of earth, then we can predict that

• A. The organism became extinct recently
• B. The extinction of organism occurred years back
• C. The time of extinction is not related to layers of earth
• D. Cannot be determined

Answer 1

The correct option is B The extinction of organism occurred years back

Fossils are remains of dead plants and animals. When plants and animals die, their bodies are buried inside the soil. the older the fossils, earlier they must have been buried inside. Year after, many bodies must have got deposited over them. So deeper the fossil layer, older it must have been.

So, option B "The extinction of organism occurred years back" is the correct answer.
