Main f actors which influenced topography shaping in Angola are geological structures and tectonic movements. The Creat Escarpment of South Africa (at least within Angola) is a tectonic feature belonging to the transitional zone between the African continent and the Atlantic ocean. Pediplanation is the.most characteristic process of landscape model ling. Like other kinds of denudation it operates on the basis of selectivity. The territory of Angola consists of two provinces - Western Angola and Eastern Angola. Western Angola occupies the Angolian and Mayor be shields and has block structure. The erosion-denudational topography prevails there. Eastern Angola (Congo and Okovango basins) is a vast alluvial plain made up of sandy sediments of Neogene age. As in South Africa several planation epochs can be distingueshed in Angola. However relics of corresponding planation surf aces hardly can be identified in modern topography under the present state of knowledge.
