Radiometric dating of earth
The element is defined by the number of protons present in the nucleus.
Carbon has six protons and six neutrons, Carbon-12 has six protons and 12 neutrons.
Fossils are then dated relative to the layers in which they were found.
The radiometric dating techniques discussed in the previous section are used in tandem with stratigraphy and biostratigraphy.
Potassium-argon dating can be used on materials such as mica, feldspar, and other minerals.
The decay of rubidium-87 into strontium-87 can also be used for dating.
This challenge is mainly headed by Creationism which teaches a young-earth (YE) theory.
A young earth is considered to be typically just 6,000 years old since this fits the creation account and some dating deductions from Genesis.
The radiocarbon method is the method for organic materials and was developed by Willard Libby in 1947.
