Figure 4. Topography and Drainage
Ghana is characterized in general by low physical relief.
Indeed, the Precambrian rock system that underlies most of the
nation has been worn down by erosion almost to a plain. The highest
elevation in Ghana, Mount Afadjato in the Akwapim-Togo Ranges,
rises only 880 meters above sea level.
There are, nonetheless, five distinct geographical regions. Low
plains stretch across the southern part of the country. To their
north lie three regions--the Ashanti Uplands, the Akwapim-Togo
Ranges, and the Volta Basin. The fifth region, the high plains,
occupies the northern and northwestern sector of the country
fig. 4). Like most West African countries, Ghana has no natural
harbors. Because strong surf pounds the shoreline, two artificial
harbors were built at Takoradi and Tema (the latter completed in
1961) to accommodate Ghana's shipping needs.
