Compare and contrast relative and absolute dating

(Hint: The Law of Superposition might help you.) According to the Law of Superposition newer rock layers form on top of already existing layers.

Radioactive dating is taking an element from a sample with a known rate of decay and invert the equation to find the time(date) from which it started to decay.

Absolute ages: Absolute dating is mostly based on isotopic measurements of certain radioactive trace elements and their decay products, not field relationships. it can assign an actual quantified age to something.

Relative dating is usually easy and often requires nothing more than careful field observation, which in many cases can be made in a few seconds.

Absolute age is the numeric age of a layer of rocks or fossils.

Absolute age can be determined by using radiometric dating. Look at the diagram below and then answer this question: We can date the layers of volcanic ash using radiometric dating, but how can we determine the absolute age of fossil A?
