It only sequences the age of things or determines if something is older or younger than other things.Some types of relative dating techniques include climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.The concept is considered by uniformitarian geologists to be a major breakthrough in scientific reasoning by establishing a rational basis for relative time measurements.However, unlike tree-ring dating -- in which each ring is a measure of 1 year's growth -- no precise rate of deposition can be determined for most of the rock layers.(a) Relative Dating This technique uses principles of stratigraphy (rock strata) and the study of fossils (palaeontology) to determine the relative ages of rocks and sediments. Field geologists' rely on a number of simple techniques for dating rocks and constructing geological successions. The Law of Strata Identified by Fossils is a little bit more complex.(relative geologic timescale) (b) Absolute Dating Following the discovery of radioactivity in 1895, radiometric dating techniques were developed to determine the absolute ages, i.e. In the succession of strata, each layer represents the geographical conditions that occurred over that area at the time the layer was deposited. ANSWER: Relative dating is used to determine the relative ages of geologic strata, artifacts, historical events, etc.

Hutton, a Scottish geologist, first proposed formally the fundamental principle used to classify rocks according to their relative ages.One known example where this assumption was used is very misleading.Ice cores showed the age of a military plane buried in the artic as thousands of years old.What can be deduced from our two distinct faunas in terms of their usefulness in the relative dating of rocks?The table below summarises key features: Gastrioceras listeri is a particularly good example of a ZONE fossil.
