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.Technology has progressed phenomenally since Steno's time.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.You have probably heard of mummies that have been dated with the Carbon-14 method.Let your TA or Professor see your Certificate of Completion once you reach that screen at the end of the activity.To obtain further practice with the concepts of Steno's laws and geologic dating, work through the Understanding Geological Time section of this assignment.These laws are a set of hypotheses that the scientific community accepts as a starting basis without absolute proof.While this may sound questionable at first, keep in mind that we also accept the Law of Gravity with out direct proof.After all, it is possible that rock layers can be disturbed, overturned, and altered in both natural and unnatural ways.Who's to say that the rocks a particular scientist is studying have not been displaced from their original positions?
