These laws are a set of hypotheses that the scientific community accepts as a starting basis without absolute proof.However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.So, we rely on radiometric dating to calculate their ages.As a member, you'll also get unlimited access to over 55,000 lessons in math, English, science, history, and more.Plus, get practice tests, quizzes, and personalized coaching to help you succeed.Scientists have developed technology that can accurately date rocks using radioactive materials which are fixed into the rocks as they form from sediments.

This dating technique is known as radiometric dating.

Now that you have discovered the method that scientists originally used to date geological features, you may be questioning the accuracy of this dating method.

After all, it is possible that rock layers can be disturbed, overturned, and altered in both natural and unnatural ways.

Following this introduction, there are several links to different sites concerning the methods scientists use to assist them in estimating the age of the Earth.

You will investigate Steno's Laws, radiometric dating, and then visit an interactive site that will help you better understand how to tell time - with geology! As you proceed through Assignment 4, be sure to compare your answers from "If Scientists Think. ." to the actual methods scientists use to estimate the age of prehistoric objects.
