This is a relatively long activity so stay focused on your work.

After all, it is possible that rock layers can be disturbed, overturned, and altered in both natural and unnatural ways.Carbon dating is used to determine the age of biological artifacts up to 50,000 years old.This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils (like those of the dinosaurs alleged to be millions of years old).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.Because this assignment is linked with your work in Assignment 3, you will have "If Scientists Think. Before scientists had modern technology to assist them in their research, they had to use their power of observation to infer the relative ages of the rocks they were studying.

The process of Relative Dating was established by Nicholaus Steno in the 1600's.

To obtain further practice with the concepts of Steno's laws and geologic dating, work through the Understanding Geological Time section of this assignment.

This portion of the assignment is an interactive web site that allows you to apply what you have learned and to learn more about how scientists tell time with geology.

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.

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.
