Geologists also use other methods - such as electron spin resonance and thermoluminescence , which assess the effects of radioactivity on the accumulation of electrons in imperfections, or "traps," in the crystal structure of a mineral - to determine the age of the rocks or fossils. A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved. This method is based on the principle that the variation in tree growth from one year to another is influenced by the degree of precipitation, sunshine, temperature, soil type and all ambient conditions and that, consequently, reference patterns can be distinguished. On the other hand, during years with exceptionally large amounts of rain the tree will form much wider growth rings. The rate of decay for many radioactive isotopes has been measured and does not change over time. For example, if an artefact, say an oil lamp, is found co-located on the same floor of a governor's dwelling, and that floor can be dated in archaeology terms by reason of the patterns employed in the mosaic, then it is assumed that in relation to the floor that the lamp is of the same age.
