Question

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

• A. The extinction of organisms has occurred recently.
• B. The extinction of organisms has occurred thousands of years 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

The correct option is B

The extinction of organisms has occurred thousands of years ago.

The correct option is B.

Explanation of the correct option:

1. Fossils are clear proof of evolution.
2. Fossils are the bodily remains or imprints of deceased plants and animals that have been preserved in layers of the Earth and rocks.
3. Older fossils are discovered deeper into the Earth.
4. The extinction of organisms is thought to have occurred thousands of years ago.

Explanation of the incorrect option:

Option A:

Recent extinction of species will be detected on the earth's topmost level.

Option C:

The position of a fossil in the earth's layer is unrelated to the moment of extinction is not true.

Option D:

1. The time of extinction can be determined.
2. Geologists and paleontologists utilize the geological time scale to determine the history of the Earth and life.
3. It is based on fossils discovered in various ages of rocks as well as radiometric dating of the rocks.

Final answer: If the fossil of an organism is found in the deeper layers of the Earth, then we can predict that the extinction of organisms occurred thousands of years ago.
