Some types of relative dating techniques include climate chronology, dendrochronology, ice core sampling, stratigraphy, and seriation.However, by itself a fossil has little meaning unless it is placed within some context.The age of the fossil must be determined so it can be compared to other fossil species from the same time period.The site provides background information about stratigraphic principles and relative time, biostratigraphy (using fossils for relative dating), and radiometric dating. The site also provides fact sheets on the age of the Earth and isochron dating. Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free.
