Radioactive carbon dating of the earth Random nude hookup
Radioactivity also gave the history of life an absolute calendar.
By measuring the atoms produced by these breakdowns inside rocks, physicists were able to estimate their ages (right).
There are many radiometric clocks and when applied to appropriate materials, the dating can be very accurate.
As one example, the first minerals to crystallize (condense) from the hot cloud of gasses that surrounded the Sun as it first became a star have been dated to 4568 plus or minus 2 million years....!! Other events on earth can be dated equally well given the right minerals.
In this article, we will examine the methods by which scientists use radioactivity to determine the age of objects, most notably carbon-14 dating.
This is an enormous branch of geochemistry called Geochronology.
It is an accurate way to date specific geologic events.
Answer 2: Yes, radiometric dating is a very accurate way to date the Earth.
We know it is accurate because radiometric dating is based on the radioactive decay of unstable isotopes.
