Radiometric dating is based on the decay of long-lived radioactive isotopes that occur naturally in rocks and minerals these parent isotopes decay to stable daughter isotopes at rates that can be measured experimentally and are effectively constant over time regardless of physical or chemical conditions. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks radioactive elements decay the universe is full of naturally occurring radioactive elements radioactive atoms are inherently unstable over time, radioactive.

Relative dating tells scientists if a rock layer is older or younger than another this would also mean that fossils found in the deepest layer of rocks in an area would represent the oldest forms of life in that particular rock formation.

Radiometric dating radioactive elements were incorporated into the earth when the solar system formed all rocks and minerals contain tiny amounts of these radioactive elements radioactive elements are unstable they breakdown spontaneously into more stable atoms over time, a process known as radioactive decay.
