The various methods of relative dating are; This method depends on the common observation that the height of the habitational area increases as the people continue to live at the same place.The deposit thus occurring forms layers depending on the nature of the material brought in by the people inhabiting the area.The earliest-known hominids in East Africa are often found in very specific stratigraphic contexts that have implications for their relative dating.Learn to think holistically about the human race with SNHU's online bachelor's in anthropology.All dating methods have limitations and can be complicated by turbation, or mixing, of layers by human or natural actions.Multiple dating methods are usually required before dates are accepted.
Historians can tell what cultures thrived in different regions and when they disintegrated.
Dating methods in archaeology establish the time and sequence of events that created archaeological deposits and layers, called strata, within those deposits. Absolute dating relies on biological, chemical (radiometric), geological/electromagnetic, or historical investigation to obtain the date range of a deposit.
(Examples of each method, respectively, are dendrochronology, carbon-14, archaeomagnetism, and the known year a city was destroyed.) Relative dating is based on stratigraphy (the tendency of younger layers to lie over older layers) and comparison of artifacts from undated sites to sites where dates are established.
But, for a single culture site the method is quite reliable.
Relative dating methods allow one to determine if an object is earlier than, later than, or contemporary with some other object.
