Compare and contrast relative and absolute dating of rocks dating russia penpal
An absolute age is one determined usually by mass-spectrometry where an isotope is measured and then an age can be calculated (a very very basic explanation).So in the end you can say this fossil is 50 thousand years old (always with an associated uncertainty).The meteorites and moon rocks are believed to have formed virtually at the same time with earth and are therefore, considered to be of the same age as earth.Absolute dating tells when the fossil was formed, relative dating compares fossils to other fossils, some fossils cannot se absolute dating so they have to use both relative and absolute dating together.Radiometric dating is another crucial technique through which the exact age can be obtained.
What can complicate relative dating is when the strata is not the right way up!
Sometimes beds of rock can turn over the other way, so be very cautious when relatively dating rocks!

In relative dating, mostly the common sense principles are applied, and it is told that which artifact or object is older than the other one.
Most commonly, the ancient factors of the rocks or objects are examined using the method called stratigraphy.
