ABSTRACT
No single criterion exists for determining when an area within Africa falls in the highland category. One arbitrary guideline delimits Africa into “high” Africa and “low” Africa, using 1000 m above sea level as the boundary between these two categories (Fig. 1.4). Included within the “high” Africa category are a diverse set of lands with little in common except altitude. They include nonvolcanic mountain ranges, such as the Atlas Mountains in Morocco; old crystalline land surfaces with the highest points being rock inselbergs, such as the Guinea Highlands; high volcanic plateaus deeply dissected by stream erosion, such as the Ethiopian Plateau; and isolated mountains, such as Kilimanjaro and Mount Kenya. The largest part of the land within the “high” Africa category consists of plateaus and lands of relatively moderate relief over large areas, such as the Serengeti “Plains” (Fig. 7.1). The Serengeti plains near the Tanzanian and Kenyan border. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9780203838914/863a4a5f-7379-4cdf-8601-470261c0460f/content/fig7_1_B.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
