After all, the scientists haven’t been around that long, have they?There are a variety of different ways to figure out how old an object is.

So if scientists wanted to measure the age of a fossil using this method, they would look for a nearby layer of igneous rock (e.g.
rock that forms from lava from a volcanic eruption)—perhaps in the rock layers above where the fossil was found, or in the layers below.
Most people think that scientists can actually measure the ages of rocks, using a method called “radiometric” or “radioisotope” dating.
More often, rocks are “dated” by the fossils they contain, based on a pre-existing belief in evolution.
Plotting an isochron (straight-line graph) is used to solve the age equation graphically.
It shows the age of the sample, and the original composition.Radiometric dating is also used to date archaeological materials, including ancient artifacts.Radiometric dating methods are used to establish the geological time scale.Those who don’t accept the Biblical account of history look for other ways to discover the age of things.One of these methods is based on a substance found in our bodies, plants and all living things—it’s called carbon. This makes the plant appear to have died many more years ago than it actually did (for example, the plant might appear to be, say, 3,000 years old, rather than 2,000).A particular isotope of a particular element is called a nuclide. That is, at some point in time, an atom of such a nuclide will spontaneously change into a different nuclide by radioactive decay.Tags: Adult Dating, affair dating, sex dating
