Transcript carbon dating Armani

• The half-life of a radioactive isotope explains
the amount of time that it takes half of the
isotope in a sample to decay.
• Carbon-14 Dating is a way to determine the
age of archeological artifacts.
• It is used in dating things such as bone, cloth,
wood, and plant fibers.
• Carbon dating is a variety of radioactive dating
which is only to matter that once lived.
• The radioactive carbon-14 combines with
oxygen to form carbon dioxide.
• The carbon-14 forms at a rate which appears
to be constant, so that by measuring the
radioactive emissions.
• Carbon-14 decays with a half life of about
5730 years by the emission of an electron of
energy.
• Scientists use a technique called radiometric
dating to estimate the ages of rocks, fossils,
and the earth.
• Many people have been led to believe that
radiometric dating methods have proved the
earth to be billions of years old.
