[tex]\bold{\red{Stratigraphy}}[/tex]: This method assumes that the lowest layer is the oldest and the topmost layer is the youngest.

➯ It follows the Law of Superposition, which states that in an undeformed sequence of sedimentary or volcanic rocks, the older rocks will be found at the bottom and the younger rocks at the top.

[tex]\bold{\red{Biostratigraphy}}[/tex]: This method uses the fossils found in the rock layers to determine their relative age.

➯ The principle of faunal succession states that fossil organisms succeed one another in a definite and determinable order, and therefore the relative ages of rocks can be established based on their fossil content.

[tex]\bold{\red{Cross-dating}}[/tex]: This method compares the fossils in one rock layer with the fossils in another layer of known age to determine the relative age of the first layer.
