Process of describing the patterns in which rock layers are deposited.
Explanation:
Stratigraphy is a field of earth sciences that studies the sequence of consecutive rock layers (stratification), with the aim of dating and describe the characteristics of the soil.
Stratigraphy is used to determine the paleogeography of an area. It also plays an important role in archaeological, paleoclimatic and paleontological research, where it is important to know from which layer a particular object, fossil or data originates and to which age it corresponds.
