Radioactive dating of rock samples yahoo Free porn chat without pay
The textbooks focus on relative dating, based on the layering of the rocks, and radiometric dating.Relative ages are assigned to rocks based on the idea that rock layers lower in the strata were deposited before rock layers that are higher.Even the use of isochron dating, which is supposed to eliminate some initial condition assumptions, produces dates that are not reliable.Despite the fact that there are many scientific problems with radiometric dating, there is a more significant problem.

Creationists do not necessarily disagree with this concept, but it can only be applied to layers that are found in one location and/or can be determined to have been deposited in a continuous layer over a very wide area.
There is also a difference in the timescale used to explain the layers.
Radiocarbon dating is one kind of radiometric dating, used for determining the age of organic remains that are less than 50,000 years old.
For inorganic matter and for older materials, isotopes of other elements, such as potassium, uranium, and strontium, are used.
