Generally speaking, scientists have developed four different methods of determining the age of the earth by using these methods, or a combination of them, the age of geological formations created by past events and even the fossilized bones of prehistoric animals can be determined. By this method, the age of oceans will equal the total salt in oceans (in grams) divided by rate of salt added (grams per year) age of earth was calculated to be 90-100 million years problems: no way to account for recycled salt, salt incorporated into clay minerals, salt deposits.

The dating method used to estimate age after something died is thecarbon dating method the carbon dating method measures thehalf-life of the carbon in the organism.
Thus, if a rock contains both uranium-238 and lead-206, the ratio of the two elements will be used to estimate the age of the sample it is conceded, however, that in order for this method to be valid, certain assumptions must be granted. Another method of determining the age of the earth is to use resources such as radiometric (carbon) dating, geologic cycles, and so forth by comparing different methods, and seeing if they align, scientists attempt to determine how old the planet is.
