Landforms: Plateaus, Highlands, and Mountains • SSA (Sub-Saharan Africa) is made up many plateaus. • They rise in elevation from the coast inland, and from west to east. • The edges of these plateaus are marker by escarpments • Steep, often jagged slopes or cliffs. • Rivers crossing plateaus dropped down the escarpments in cataracts. • Large water-falls • SSA has relatively few mountains • Most African mountains dot the Eastern Highlands • Include Mt. Kilimanjaro and Mt. Kenya • Ruwenzori Mountains • Located West of the Eastern Highlands • Divides Uganda and the Democratic Republic of the Congo. • Covered in snow and cloaked in clouds, its also called the “Mountains of the Moon”

The Land: The Great Rift Valley • Stretches from Syria in Southwest Asia to Mozambique. • Rift Valley – a large crack in the earth’s surface formed by shifting tectonic plates • Formed million of years ago, as plate movements created the system of faults or fractures in the earth’s crust. • The Great Rift Valley lays in these faults • Two Branches: • 1. Volcanic Mountains on its edges • 2. Deep lakes that run parallel to its length

Water Systems: Land of Lakes • Most of the Regions lakes are located near the Great Rift Valley • Lake Victoria – Africa’s largest lake, lies between the eastern and western branches of the Rift • Lake Volta: • One of the largest man-made lakes • Created in the 1960s by damming the Volta River south of Ajena, Ghana • Supplies Ghana with irrigation water, electricity, and fishing.
Water Systems: River Basins • Niger River • Means “Great River” • Important for agricultural, transportation, and tourism. • At Aboh in southern Nigeria the river splits into a giant delta, measuring 150 miles long and 200 miles wide (at its broadest). • Delta - a triangular tract of sediment deposited at the mouth of a river, typically where it diverges into several outlets.

Water Systems: The Congo River • Facts: • 2,900 miles long • Largest network of navigable waterways in Africa • Has great and dangerous rapids • Plunges more than 900 feet in numerous cataracts not far from where it reaches the Atlantic Ocean • Meets the Atlantic Ocean through a deep estuary • Estuary - a partially enclosed body of water along the coast where freshwater from rivers and streams meets and mixes with salt water from the ocean.
