GENERAL KNOWLEDGE

Detailed explanation-1: -Radiocarbon dating (usually referred to simply as carbon-14 dating) is a radiometric dating method. It uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbon-bearing materials up to about 58, 000 to 62, 000 years old.

Detailed explanation-2: -Uranium–lead radiometric dating involves using uranium-235 or uranium-238 to date a substance’s absolute age. This scheme has been refined to the point that the error margin in dates of rocks can be as low as less than two million years in two-and-a-half billion years.

Detailed explanation-3: -To determine the ages in years of Earth materials and the timing of geologic events such as exhumation and subduction, geologists utilize the process of radiometric decay. Geologists use these dates to further define the boundaries of the geologic periods shown on the geologic time scale.

Detailed explanation-4: -Radioactive elements decay Afterwards, they decay at a predictable rate. By measuring the quantity of unstable atoms left in a rock and comparing it to the quantity of stable daughter atoms in the rock, scientists can estimate the amount of time that has passed since that rock formed.

Detailed explanation-5: -Radiocarbon dating is the most common method by far, according to experts. This method involves measuring quantities of carbon-14, a radioactive carbon isotope-or version of an atom with a different number of neutrons. Carbon-14 is ubiquitous in the environment.
