What is relative dating in terms of fossils Gosport swingers webcam
Fossils are important for working out the relative ages of sedimentary rocks.
Throughout the history of life, different organisms have appeared, flourished and become extinct.

Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence.
It is possible to tell the number of years ago a particular rock or archeological site had been formed.
Two broad categories of classification methods are relative dating and absolute dating.
This gives away the true age of the fossil that contains C-14 that starts decaying after the death of the human being or animal. Absolute Dating • Dating techniques are used in archeology to ascertain the age of old artifacts and a broad classification of these methods bifurcates them in relative dating and absolute dating • Relative dating comes to a conclusion based upon the study of layer formation of rocks.
Upper most layers are considered the youngest while the lowermost deposition is considered as oldest.
This is possible because properties of rock formations are closely associated with the age of the artifacts found trapped within them.
The method of reading the order is called stratigraphy (layers of rock are called strata).
Relative dating does not provide actual numerical dates for the rocks.
This type of dating employs many dating techniques like atomic clocks, carbon dating, annual cycle methods, and trapped electron method.
Dendrochronology is another of the popular method of finding the exact age through growth and patterns of thick and thin ring formation in fossil trees.
