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.
