Radiometric or Absolute Rock Dating
Relative dating instead allows for identifying the sequential order of geological events one relative to the other. David Drayer Jan 15, absolute dating is based on calculations of the age of rock strata based on absolute dating strata lives of minerals, relative dating is based on the assumed age of fossils found in the strata and the laws of super imposition. Explanation: Absolute dating is actually a misnomer.
The absolute dating is based on calculation of half life. The results are often determined by the estimates of the presumed age of the strata based on relative ages. The age determined by relative dating is based on the rules of super imposition and the presumed age of strata based on fossils.

The most useful tool in dating strata is radiometric dating of materials. A radioactive isotope such as uranium decays at a very regular and well-known rate. Relative dating places fossils in a temporal sequence by noting their positions in layers of rocks, known as strata. As shown in Numerical dating relies on the decay of radioactive elements, such as uranium, potassium, rubidium and carbon.
