what five principles are used in relative dating-84

The underlying principle of stratigraphic analysis in archaeology is that of superposition.This term means that older artefacts are usually found below younger items.

The Creationists wrongly believe that their understanding of evolution is what the theory of evolution really says, and declare evolution banished.Archaeology dating techniques can assure buyers that their item is not a fake by providing scientific reassurance of the artefact's likely age.Archaeological scientists have two primary ways of telling the age of artefacts and the sites from which they came: relative dating and absolute dating.Explanations of why these statements are wrong are given below.They are brief and therefore somewhat simplified; consult the references at the end for more thorough explanations.To examine the world we live in, we must expand our concept of what a long time period is.

Even thousands of years is inadequate..must think in terms of millions and billions of years.

Compared with the RBCs, a 10% Na Cl solution is hypertonic while a 0.1 % Na Cl is hypotonic.

Since the latter solution is almost pure water, the blood cells are actually hypertonic by comparison.: Movement of water molecules from a region of high concentration to a region of lower concentration through a differentially permeable cell membrane.

"Evolution has never been observed." Biologists define evolution as a change in the gene pool of a population over time.

One example is insects developing a resistance to pesticides over the period of a few years. Jorg, 1992, "Evidence for rapid speciation following a founder event in the laboratory." Evolution 46: 1214-1220).

: When using a compound microscope this term refers to the thickness of the subject that is in focus.
