Differentiate between relative and radiometric dating of fossils Free down load xxx sexy zaire
This Science Struck post enlists the differences between the absolute and relative dating methods.
Geological specimens that are unearthed need to be assigned an appropriate age.
Stratigraphy: The oldest dating method which studies the successive placement of layers.
“Radiocarbon Date Calibration Curve” By Howard Morland – Own work based on information from: Reimer, P.
To find their age, two major geological dating methods are used.
These are called relative and absolute dating techniques.
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.
