Geologists frequently look at the relationships among rock layers. which statement best describes the information geologists get from studying these relationships? a. they get a sense of the history of the area they are investigating. b. they can tell how old the rocks are. c. they can tell how dense the rocks are. d. they get a sense of which rocks are the most valuable.

The correct answer is:

A) They get a sense of the history of the area they are investigating

Explanation:

The age of the rocks located in the different layers is estimated because the absolute age is checked by measuring the radioactive decay of the isotopes of the elements.

The density of a rock depends on both its mineral composition and its porosity and various procedures are necessary to determine the reliable average values.

The value of the rocks is relative and is determined based on the objectives of the geological survey.

The Answer is A) They get a sense of the history of the area they are investigating.
