ABSOLUTE AGE OF ROCK
ROCKS ARE AN INTERESTING BUT MYSTERIOS THINGS BECAUSE, THERE ARE ALL KINDS OF ROCKS AND
WAYS THEY CAN BE FORMED AND HOW THERE FORMED. THE MEANING ABSOLUTE AGE OF ROCK IS HOW OLD
A CERTAIN ROCK IS, AND KNOW THAT ME CAN FIND OUT HOW OLD THE EARTH IS IN YEARS, MONTHS OR
DAYS. 
CARBON 14 IS AN ELEMENT FOUND IN A ONCE LIVING THING, AND IT IS USED ONORGANIC MATERIAL
LESS THAN 50,000 YEARS OLD, WHICH INCLUDES MANY THINGS SUCH AS HUMAN REMAINS AND
ARTIFACTS, BUT EXCLUDES MOST FOSSILS
ABSOLUTE DATING COMPLEMENTS RELATIVE DATING BY PROVIDING AN EXACT OR ABSOLUTE AGE FOR AN
OBJECT, SUCH AS 50 MILLION YEARS BEFORE PRESENT, IN YEARS BEFORE RELIABLE FORMS OF
ABSOLUTE DATING BECAME BECAME AVAILABLE THROUGH THE FOUNDING OF RADIOMETRIC DATING
METHODS. THESE METHODS ARE BASED ON THE KNOWN, REGULAR DECAY OF CERTAIN REDIOACTIVE
ELEMENTSITTO OTHER ISOTOPES OR DAUGHTER PRODUCTS THE WAY IT WORKS IS, BY MEASURING THE
PARENT AND DAUGHTER PRODUCT IN A ROCK SAMPLE, ITS EXACT AGE CAN BE CALCULATED. 
RADIOACTIVE DECAY IS WHEN MOST ELEMENTS COMPRISE MORE THAN ONE ISOTOP. SOME ARE STABE AND
HAVE BEEN ARUND SINCE THE BEGINNING OF THE SOLAR SYSTEM BUT OTHERS ARE UNSTABLE AND BRAEK
DOWN BY RADIOACTIVE DECAY OF THEIR NUCLEI TO ANOTHER ISOTOPES, USUALLY OF OTHER ELEMENTS.

I FOUND THIS TOPPIC ON ABSOLUTE AGE OF ROCK VERY EXITING TO DO AND I ENJOYED IT I LEARNED
ALOTE OF INFORMATION SUCH AS HOW TO MEASURE HOW OLD A ROCK IS OR THE EARTH IS, SO I HOPE
YOU LIKE THIS PAPER.
