which event is most likely if an index fossil is found in a layer at location 1, but the layer and index fossil are not found at a nearby location 2, which is known to be the same relative age?\nthe layer at location 2 is too old to contain fossils.\nthe locations were not close together.\nthe organism did not exist at location 2.\nthe layers at location 2 formed much earlier than those at location 1
Answer
Brief Explanations:
Index fossils are used to date rock layers. If an index fossil is in a layer at location 1 but not in a nearby layer at location 2 which is of the same relative age, it implies the locations were not close together when the organisms lived. The other options are inconsistent with the nature of index - fossils and relative - age dating.
Answer:
The locations were not close together.
