1) Archeology is the science that studies the changes that take place from the ancient societies to the present ones, through material remains dispersed in geography and conserved over time. Archeology can be considered both a social science and a branch of the humanities. The archaeological information based on pseudoscience is that which does not follow a valid scientific method, and therefore can not be reliably verified.
2) Archeometry is a scientific discipline that uses physical or chemical methods for archaeological studies. These methods include the studies of sedimentology, botany, archaeozoology, anthropology, analysis of materials. The objective is the dating of objects and vestiges of archaeological sites, the characterization of materials, the determination of their physical and chemical properties, the type of technology used, the origin of these materials, etc.
3) Its main objective is the study of changes in social organization, as well as the diversity of human behavior (economic, political, ideological) in the past. This is usually achieved through the study of material remains in defined spatial and temporal contexts. It is for this reason that archeology has, in the first place, a particular interest in the clear definition of temporal sequences (diachronic divisions), which are specified in periods; although there are archaeologists who tend to specialize in a period, they also pay attention to events before and after that period; this pattern is an exception to urban archeology, where it is not possible to establish temporal or diachronic divisions. Second, archeology focuses on specific spatial frames (synchronous divisions) such as "regions" or political units, "sub-regions" or communities, and "local areas-sites" or domestic units and their associated remains (places). of activity, graves, among others). Unlike History, deep temporal sequences and diversity of spaces provide it with varied and complementary scales of analysis, unique features that allow it to reconstruct and give explanations about social changes and the diversity of human social organization.
