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.

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

Steno developed a set of Laws (Steno's Laws) to help explain his method of inferring the ages of geological structures.

These laws are a set of hypotheses that the scientific community accepts as a starting basis without absolute proof.

Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).

The question should be whether or not carbon-14 can be used to date any artifacts at all? There are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more 50,000 years old.

Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.

This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.

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.

From this information, scientists can accurately infer the age of the test material.

Continue to the Radiometric Dating portion of this assignment through use of a virtual web site.

The web site is simple, especially at the begnining, yet allows you to visualize relationships among the main concepts you have been studying.

    “Oh no,” I said, “I don’t really own anything worth insuring, to be honest.” “It’s not for you,” she replied, puzzled.
