Scientists agree that radiometric-dating techniques offer the most concrete evidence of any dating system for answering questions about the age of Earth.

It is used this way and in the names of many minerals, such as antimonial arsenic, copper, and nickel. antimonial CATEGORY: geology DEFINITION: A brittle metallic substance that has been used in the preparation of yellow pigments for enamel and porcelain painting.

It forms a fourth constituent in alloys, along with nitrogen, phosphorus, arsenic, bismuth, and some others in forming triads and pentads.

Radiometric dating can be compared to an hourglass.

When the timepiece is turned over, sand grains fall from the top of the hourglass to the bottom.
