Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence.

The method of reading the order is called stratigraphy (layers of rock are called strata).

Relative dating does not provide actual numerical dates for the rocks.

Fossils are important for working out the relative ages of sedimentary rocks.

Species extinctions, often referred to as “tops,” are used as horizons of correlation.
