Some archaeological strata (often termed as contexts or layers) are created by undercutting previous strata.An example would be that the silt back-fill of an underground drain would form some time after the ground immediately above it.This section presents many basic concepts that are universal to all physical sciences.1. A mineral is a naturally occurring, inorganic (never living) solid with a definite internal arrangement of atoms (crystal structure) and a chemical formula that only varies over a limited range that does not alter the crystal structure.
In addition, basic geologic principles can be applied to resolving the order of events leading to the formation of rocks and landscape features. Cross Sections - interpretations of vertical views of geologic features below the surface.For example, based on the primate fossil record, scientists know that living primates evolved from fossil primates and that this evolutionary history took tens of millions of years.By comparing fossils of different primate species, scientists can examine how features changed and how primates evolved through time.It is possible to tell the number of years ago a particular rock or archeological site had been formed.Two broad categories of classification methods are relative dating and absolute dating.
