Changes

The northern Chilean desert contains great mineral wealth, principally [[copper]]. The relatively small central area dominates the country in terms of population and agricultural resources. This area also is the cultural and political center from which Chile expanded in the late 19th century, when it incorporated its northern and southern regions. Southern Chile is rich in forests [[forest]]s and grazing lands and features a string of volcanoes [[volcano]]es and lakes[[lake]]s. The southern coast is a labyrinth of fjords[[fjord]]s, inlets[[inlet]]s, canals[[canal]]s, twisting peninsulas[[peninsula]]s, and islands''island''s. The [[Andes ]] Mountains are located on the eastern border.
