dating site for truck drivers - Carbon dating of objects
The most popular method of radio dating is radio carbon dating which is possible because of the presence of C-14, an unstable isotope of carbon.
C-14 has a half life of 5730 years which means that only half of the original amount is left in the fossil after 5730 years while half of the remaining amount is left after another 5730 years.
It is produced in the upper atmosphere by radiation from the sun.
It is possible to tell the number of years ago a particular rock or archeological site had been formed.
Two broad categories of classification methods are relative dating and absolute dating.
Founded in 2002 by Nobel Laureate Carl Wieman, the Ph ET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations.
Ph ET sims are based on extensive education research and engage students through an intuitive, game-like environment where students learn through exploration and discovery.
In short, unless you have evidence to the contrary, you should assume that most of the carbon in a fossil is from contamination, and is not originally part of the fossil. The nuclear tests of the 1950's created a lot of C14.
Also, humans are now burning large amounts of "fossil fuel".
That causes a dating problem with any animal that eats seafood. After about ten half-lives, there's very little C14 left.
So, anything more than about 50,000 years old probably can't be dated at all.
However, archeologists still require further information to find out the items that are oldest and those that are youngest in the order.Tags: Adult Dating, affair dating, sex dating
