Absolute dating ppt
These use radioactive minerals in rocks as geological clocks.
The atoms of some chemical elements have different forms, called isotopes.
In other words, we can say that in relative dating the archaeologist determines that which of the two fossil or the artifacts are older.
Contrary to this, absolute dating is the technique, using which the exact age of the artifacts, fossils, or sites are ascertained.
Isotopes are important to geologists because each radioactive element decays at a constant rate, which is unique to that element.
Other than rocks, fossils are the other most important elements in relative dating as many organisms have there remain in the sedimentary rocks.
The absolute dating is more reliable than the relative dating, which merely puts the different events in the time order and explains one using the other.
Radiometric dating is another crucial technique through which the exact age can be obtained.
Relative Dating and Absolute Dating are two types of such techniques which are under practice to determine the age of the fossils, objects or civilizations.
The relative dating is the technique in the Geology through which the age is determined with relation to the other objects.
