Radioactive dating rocks and fossils

Radioactive decay is a natural process and comes from the atomic nucleus becoming unstable and releasing bits and pieces.These are released as radioactive particles (there are many types).This decay process leads to a more balanced nucleus and when the number of protons and neutrons balance, the atom becomes stable.

Radioactive dating is a method of dating rocks and minerals using radioactive isotopes.

This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Some do not change with time and form stable isotopes (i.e.

The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.

This restriction extends to animals that consume seafood in their diet.

Learn about different types of radiometric dating, such as carbon dating.

Understand how decay and half life work to enable radiometric dating.

Many isotopes have been studied, probing a wide range of time scales.

C and counting the amount of each) allows one to date the death of the once-living things.

This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.
