Picture relative dating

Fluorine dating: Bones from fossils absorb fluorine from the groundwater.The amount of fluorine absorbed indicates how long the fossil has been buried in the sediments.➤ It determines the age of a rock/object using radiometric techniques.➤ Absolute dating is quantitative.➤ This technique helps determine the exact age of the remains.➤ It is more specific than relative dating.➤ Absolute dating is expensive and time-consuming.➤ It works best for igneous and metamorphic rocks.The object's approximate age can then be figured out using the known rate of decay of the isotope.For organic materials, the comparison is between the current ratio of a radioactive isotope to a stable isotope of the same element and the known ratio of the two isotopes in living organisms.Cross dating: This method compares the age of remains or fossils found in a layer with the ones found in other layers.The comparison helps establish the relative age of these remains.Thermoluminescence: It determines the period during which certain object was last subjected to heat.It is based on the concept that heated objects absorb light, and emit electrons. A Venn diagram depicts both dating methods as two individual sets.

It is based on the concept that the lowest layer is the oldest and the topmost layer is the youngest.Our planet inherits a large number of artifacts and monuments bestowed upon us by older historic civilizations.These remains are subjected to dating techniques in order to predict their ages and trace their history.To find their age, two major geological dating methods are used.These are called relative and absolute dating techniques.
