Most absolute dating techniques utilize predetermined rates of radioactive decay to calculate the elapsed period of time. stratigraphy), absolute dating is a quantitative measurement allowing determination of a specific time, rather than relative.

Absolute dating provides a numerical age for the material tested, while relative dating can only provide a sequence of age.

Scientists can use more than one method to determine the age of the Earth.

Recall that relative age simply states that an object is older or younger than another object.

The circles inside a tree trunk are called growth rings.

A growth ring is one new layer of alternating light and dark colored wood around the trunk of a tree each year.

Therefore, we can obtain numeric dates of many rocks that represent important events in Earths distant past.
