The layers of rock at the base of the canyon were deposited first, and are thus older than the layers of rock exposed at the top (principle of superposition).

In the Grand Canyon, the layers of strata are nearly horizontal.

Numerical ages estimate the date of a geological event and can sometimes reveal quite precisely when a fossil species existed in time.

A fossil can be studied to determine what kind of organism it represents, how the organism lived, and how it was preserved.

However, by itself a fossil has little meaning unless it is placed within some context.

The study of strata is called stratigraphy, and using a few basic principles, it is possible to work out the relative ages of rocks.

Just as when they were deposited, the strata are mostly horizontal (principle of original horizontality).

  2. May 20, 2011. Geologists often need to know the age of material that they find. They use absolute dating methods, sometimes called numerical dating, to give rocks an actual date, or date range, in number of years. This is different to relative dating, which only puts geological events in time order.
