Detailed explanation-1: -Superposition: The most basic concept used in relative dating is the law of superposition. Simply stated, each bed in a sequence of sedimentary rocks (or layered volcanic rocks) is younger than the bed below it and older than the bed above it.
Detailed explanation-2: -Relative Dating Methods Stratigraphy: Assuming that soil layers in a deposit accumulate on top of one another, and that the bottom layers will be older than the top layers, stratigraphy allows archaeologists to construct a relative chronological sequence from the oldest (bottom) to youngest (top) layers.
Detailed explanation-3: -Relative dating Stratigraphy is the study of the order of the layers of rocks and where they fit in the geological timescale. This method is most effective for studying sedimentary rocks. Cross dating is a method of using fossils to determine the relative age of a rock.
Detailed explanation-4: -Absolute dating is more accurate than relative dating because it uses the known decay rates of unstable isotopes to determine the age of rock or organic material with a much narrower range of age than relative dating.
