Question

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

• A. The extinction of organism has occurred recently
• B. The extinction of organism has occurred thousands of year ago
• C. The fossil position in the layers of earth is not related to its time of extinction
• D. Time of extinction cannot be determined.

Answer 1

Answer: (B)

The extinction of organism has occurred thousands of year ago

Fossils are dead remains of plants and animals that lived on Earth but are no more living. As these animals and plants die, their dead bodies are covered with layers of sediments brought by various agencies like wind and water. As more and more sediments are deposited, older remains are pushed deeper, while relatively recent remains are expected to be found closer to the Earth's present surface.
