The principle of superposition states that the layer which lies at the bottom is older than the one on top of it.

In stratigraphic relative dating, the succession of layers can be seen as the timeline of its formation or deposition.

Biostratigraphy: Layers get deposited above one another, over time, and fossils get trapped in these layers.

When we find two fossils in the same strata of soil, we assume that both fossils were deposited during the same time period.

The absolute age of these events need not inevitably be known.

Grand Canyon is a gorge located in Northern Arizona, USA. While some of the layers are uplifted, most of the landform is left undisturbed by nature.

The amount of fluorine in the fossils thus increases.

Archeology refers to the study of history of mankind by excavating ancient sites.Geology refers to the study of the rocks and sediments that to a great extent compose the Earth.Stratigraphy: This oldest relative dating technique in the branch of geology, as the name suggests, focuses mainly on the strata.Our planet Earth consists of numerous rocks and formations.Archeologists, geologists, and anthropologists primarily make use of relative dating techniques to understand the sequence of events, in order to establish the facts such as the time period of formation of planet Earth.
