Describe how carbon 14 is used as a dating method
Before the advent of absolute dating methods in the twentieth century, nearly all dating was relative.
The main relative dating method is stratigraphy (pronounced stra-TI-gra-fee), which is the study of layers of rocks or the objects embedded within those layers.
By measuring the amount of carbon-14 remaining, scientists can pinpoint the exact date of the organism's death.
The range of conventional radiocarbon dating is 30,000 to 40,000 years.
