Answer 1

Answer:

The Great Escarpment – The Great Escarpment, although, occupies a very small area, the nature of its slope and the effect it has on the climate makes it a separate physiographic region. The eastern side of the Highlands is demarcated because of the escarpment. In this region, the altitude of the escarpment is 790m. In some regions, the height decreases gradually. The escarpment is very steep particularly from Sao Paulo to Porto Alegre. The escarpment act as a barrier to the Southeast Trade winds giving rise to the rain- -shadow area in the northeastern part of the highlands. The region to the north of this area is called ‘Drought Quadrilateral.

The Great Escarpment is a major geological formation in the southern part of Africa, and a large portion of its areas lies within the borders of the nation of South Africa. It extends to form the border between Zimbabwe and Mozambique and in the western region, it continues up to northwards into Angola and Namibia. There are different names given to various stretches of the Great Escarpment, and they are Drakensberg, the Schwarzrand, the Serra da Chela in Angola, and the Khomas Highlands in Namibia. Sudden erosion of rivers of coastal plains resulted into the formation of The Great Escarpment, and the plateau edge rocks sharply define it. The Drakensberg area of the Escarpment has the basalt lava, which overlie on top of the softer sandstone.
