Abstract
The study deals with the relationship among the knowledge about a territory that someone belongs to, from a sociopolitical perspective, the identity associated with the environmental aspects (Ecological regional identity), and socio-identity believe such as the regionalism and the essentialism. A total of 300 volunteers, who live in Austral Patagonia, participated answering instruments about general knowledge related to the Antarctica, ecological regional identity, regionalism, and essentialism. The results show that although the identification of the Antarctic as part of the own social identity resulted to be linked to the knowledge about the territory, the socio-identity variables show to be stronger. The results are discussed around the relative importance of the emotional and cognitive factors in the construction of the social identity linked with the territory
