Isotope dating method

Its crust is continually being created, modified, and destroyed.

As a result, rocks that record its earliest history have not been found and probably no longer exist.

Wiens has a Ph D in Physics, with a minor in Geology.

His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.

Far from being data, these dates are actually interpretations of the data.

As discussed before, the assumptions influence the interpretation of the data.

Nevertheless, there is substantial evidence that the Earth and the other bodies of the Solar System are 4.5-4.6 billion years old, and that the Milky Way Galaxy and the Universe are older still.

So, we rely on radiometric dating to calculate their ages.The amount of the isotope in the object is compared to the amount of the isotope's decay products.The object's approximate age can then be figured out using the known rate of decay of the isotope.It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.
