History of absolute dating

The principle of superposition builds on the principle of original horizontality.

Layers of rock are deposited horizontally at the bottom of a lake (principle of original horizontality).This is the principle of cross-cutting relationships.The principle states that any geologic features that cut across strata must have formed after the rocks they cut through (Figures 2 and 3).Relative dating puts geologic events in chronological order without requiring that a specific numerical age be assigned to each event.Second, it is possible to determine the numerical age for fossils or earth materials.

According to the principle of original horizontality, these strata must have been deposited horizontally and then titled vertically after they were deposited.
