Absolute time has dimension.
Relative time is determined from fossils and based upon the age relationships between target and subject specimens. Absolute time has dimension and seeks to ascertain the numerical or elapsed time in the existence of fossils or subjects, typically done through measures known as radiometric dating methods. According to the University of Calgary, absolute time measurements can be used to validate (or calibrate) the relative timescale, producing two integrated methods for establishing age determination.
Instructions
1. Envision time as a physical representation of the formation of rock on the earth's core. Relative time would be determined from the physical subdivisions of rock and absolute time would be determined from the measurements taken from the rocks -- using radiometric equipment -- to determine how long they have been there.
2. Use radiometric dating. Radioactive elements found in rocks decay at a constant rate. The radioactive dating instruments help detect the presence of isotopes to ascertain aging. For example, igneous rocks contain matter consistent to the half life of uranium that is approximately 4.5 billion years old.
3. Consider varve dating. Varve is the accumulation of sediment over a year's time in a region or space that is usually impacted by the influence of hot or cold temperatures. For example, the varve of one lake could be correlated to other lakes to determine the approximate age, in years.
4. Consult a geologist. Research in stratigraphic (rock characteristics) analysis, evolution of fossils and cretaceous (dinousaurs) time periods is a good starting point to get the basic principles.
