Difference between relative dating and radioactive dating
Dating is a technique used in archeology to ascertain the age of artifacts, fossils and other items considered to be valuable by archeologists.There are many methods employed by these scientists, interested in the old, to get to know the age of items.by this method, the age of the earth has been estimated to be about 4.any technique that assigns a certain age or date is a form of absolute dating.It is clear then that absolute dating is based upon physical and chemical properties of artifacts that provide a clue regarding the true age.This is possible because properties of rock formations are closely associated with the age of the artifacts found trapped within them.
Dendrochronology is another of the popular method of finding the exact age through growth and patterns of thick and thin ring formation in fossil trees.However, archeologists still require further information to find out the items that are oldest and those that are youngest in the order.It is left for absolute dating to come up with the precise age of an artifact.The elements embedded in the Earth's crust decay over time because they are very unstable.
When these elements decay and turn into other elements, scientists measure the difference between the original element and its decayed form.
Radiometric dating works by determining the ratio of the number of isotopes of an element and the number of isotopes the element it turns into over time.
