Most absolute dates for rocks are obtained with radiometric methods. These use radioactive minerals in rocks as geological clocks. The atoms of some chemical elements have different forms, called isotopes. These break down over time in a process scientists call radioactive decay.Most absolute dates

How do we date rocks?

To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.

What is the absolute age of a rock?

Absolute age is the numeric age of a layer of rocks or fossils. Absolute age can be determined by using radiometric dating.

Can rocks live?

Rocks themselves are not alive. It is important for the rock to have been stored in healthy sea water for several weeks at the retail outlet, so as to ensure that there are no dying organisms such as sponges on its surface.
