Radioisotope methods of dating dating virtual worlds for kids

The technique of comparing the abundance ratio of a radioactive isotope to a reference isotope to determine the age of a material is called radioactive dating.Many isotopes have been studied, probing a wide range of time scales.It is possible to measure the ratio of the different radioactive parent isotopes and their daughter isotopes in a rock, but the ratios are not dates or ages.

If any of these three conditions is not accurately known, the hourglass will give an inaccurate measure of time.

Radiometric dating is based on the fact that radioactive isotopes decay to form isotopes of different elements.

The method of calculating radiometric dates is like using an hourglass.

You can use the hourglass to tell time if you know several things: the amount of sand in the top of the hourglass when it started flowing, the rate that the sand flows through the hole in the middle, and that the quantity of sand in each chamber has not been tampered with.

However, there are many methods that can be used to determine the age of the earth or other objects.

The textbooks focus on relative dating, based on the layering of the rocks, and radiometric dating.

The man's body was recovered and pieces of tissue were studied for their C content by accelerator mass spectroscopy.

The best estimate from this dating technique says the man lived between 33 BC. From the ratio, the time since the formation of the rock can be calculated.

The Bible gives us a much more reliable history of the earth as it was recorded by God.
