Quiz on carbon dating
Since a radioactive substance such as carbon 14 has a known half life the amount of carbon 14 remaining in an object can be used to date that object. You didn't know a lot about the element carbon, but you finished the quiz, so you know more now. If you were an allotrope, you'd be a sparkling diamond.Radioactive isotopes absorbed from seawater by the animal are incorporated into the skeleton, where they begin to undergo radioactive decay.Radiometric dating will reveal the age of individual corals on the seamount.Scientists can use the clocklike behavior of these isotopes to determine the age of rocks, fossils, and even some long-lived organisms.Isotopes are forms of an element that have the same number of electrons and protons but different numbers of neutrons.Some of these atomic arrangements are stable, and some are not.
Isotopes decay at an exponential rate that that can be described in terms of half-life.
For humans, the steady movement of the hands on a clock marks off the seconds and the hours.
In nature, the constant decay of radioactive isotopes records the march of years.
Use your submersible to travel about the seamount and drill samples from the skeletons of living and dead corals.
Then calculate either the percentages or ratio of parent to daughter isotopes from the isotopic data measured in each sample.
