describor 2
|
teh history of the earth can be subdivied into units of time according to geological and biological processes: these subdivisions called Geological time scale
|
|
|
|
descriptor 3
|
the study of fossils, rock stratigraphy and radiometric dating have contributed to creating teh geiological time scale

RADIOMetric dating |
TEH RADIOMETRIC DATING OF ROCKS, AND THE ANALYSIS OF FOSSILS
|
|
|
|
B) THE GEOLOGICAL TIME SCALE-
RADIOMetric dating |
the dating of materials by analyzing the decay of radioactive isotopes incorpoerated them when they were formed
|
|
|
|
B) THE GEOLOGICAL TIME SCALE-fossilazation
|
we saw sedimetary roks formed, while particles accumulate, living things theri traces get buried in process
-which increase pressure & chemical changes, particles compressed into rocks and traces of life are trapped with become fossils |
