Disadvantages of relative dating in geology

Keep these principles in mind as you progress through the rest of the activities in this assignment.It would benefit your understanding of this material if you studied the rest of this website on your own, but it is not required for class.From this information, scientists can accurately infer the age of the test material.

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.

By looking at layers of rocks, scientists can tell which layers are older or newer than others; however, they can not tell exactly how old these layers are.

Technology has progressed phenomenally since Steno's time.

Answer the questions about each aspect of radiometric dating as you move through the various exercises of the Radiometric Dating Lab.

If you have an incorrect answer be sure to figure out why that answer was wrong and what is the correct answer.

You have probably heard of mummies that have been dated with the Carbon-14 method.

The Carbon-14 method measures the amount of radioactive carbon-14 in a previously living artifact.

Part 2 explains how scientists run into problems when they make assumptions about what happened .
