What is the use of radiometric dating

Relative dating puts geologic events in chronological order without requiring that a specific numerical age be assigned to each event.Second, it is possible to determine the numerical age for fossils or earth materials.

For example, based on the primate fossil record, scientists know that living primates evolved from fossil primates and that this evolutionary history took tens of millions of years.

There are three general approaches that allow scientists to date geological materials and answer the question: "How old is this fossil?

" First, the relative age of a fossil can be determined.

Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free.

These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing.
