Detailed explanation-1: -The formula for calculating absolute age of a layer by this method of counting is: Absolute age in years (A) = time elapsed since the formation of the most recent layer (R) plus (the number of layers (N) lying above the layer in question multiplied by the duration (D) of the depositional cycle).
Detailed explanation-2: -To find the specific age of an object, archaeologists use absolute dating. Absolute dating methods measure the physical properties of an object itself and use these measurements to calculate its age. One of the most useful absolute dating methods for archaeologists is called radiocarbon dating.
Detailed explanation-3: -Absolute age is generally determined using a technique called radiometric dating, which uses radioactive isotopes of elements in the rock to estimate the age of the rock. Atoms are made of three particles: protons, electrons, and neutrons.
Detailed explanation-4: -Absolute dating finds the actual age of the object, this would be like you saying you’re 15 and your sister is 11. In geology, absolute dating can tell us the approximate age in years of the rock. The main way absolute dating is carried out is by Radiometric dating.
