What is relative dating
Relative age dating is used to order geological events and the rocks they leave behind. The process of interpreting the order is known as stratigraphy (layers of rock are called strata). Relative age dating does not yield precise numerical dates for the rocks.
What is the basic difference between relative and absolute dating?
Relative age dating techniques
Relative age dating methods
Stratigraphy: Stratigraphy allows archaeologists to build a relative chronological sequence from the oldest (bottom) to youngest (top) layers by assuming that soil layers in a deposit accumulate on top of one another and that the bottom layers are older than the top layers. Artifacts discovered in these strata are at least as ancient as the deposit where they were discovered.
Seriation: Seriation, a method used in the mid-twentieth century, examines variations in certain types of objects found at a location. A chronology is built on the premise that one cultural style (or typology) would gradually replace an older style over time.
Fluorine dating: a method of determining how long a specimen has been underground by analyzing how much of the chemical fluorine has been absorbed by bones from the surrounding soils.
