Andes
The Andes or Andean Mountains () are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. This range is about long, about wide (widest between 18° south and 20° south latitude), and of an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina.
Andean states
When grouped as "the Andean states", the emphasis is on the mountainous regions of these countries. For example, the Argentine "pampas" are not part of the Andean region, but western Argentina along with Chile is part of the Andean region. Venezuela, Colombia, Peru, Ecuador and Bolivia are part of the Andean Community (a trade grouping), and each contains Amazon Rainforest and Amazonian indigenous people as well as Andean mountains.
