Abstract (in english)
   The origin of Andes is connected with convergence of continental South-American plate and the oceanic Nazca plate. They are fault-fold type of mountains and part of a circumpacific mountain system. Paleogeographical development of Andes should be considered not only in terms of orogenesy and following exogenous processes, but also with climate changes. The Andes has undergone uplift and subsidence in different parts at a different time. This suggests that some parts of the mountain system have risen above the regional snow - line as the Quaternary era progressed, whereas other parts have been above the snow - line already since Pliocene. Landscape evolution is mainly a result of strong uplift, frost weathering, water and glacial erosion and slope movements. Seismic activity plays a significant role as well, especially in connection with sudden relief building events
