Answer

Brief Explanations:

Index fossils are fossils that are used to date the rock layers in which they are found. They are widespread geographically and existed for a relatively short period of time. By comparing the index - fossils in rock layers at different locations, scientists can correlate the rock layers and determine their relative ages.

They aid in comparison of rock layers at distant locations.
