Landforms
• South of the Sahara is considered a transition area between the desert climate and savanna
• Transition zone- physical area in which land undergoes a radical change.

Landforms
• Not only is the transition zone a physical divider in Africa, it is also a cultural divider
– North Africa=Muslim
– South of Sahara=Christian and local religions
![Page 5: Chapter 20: The Transition Zone - anderson1.org€¦ · Landforms •Not only is the transition zone a physical divider in Africa, it is also a cultural divider –North Africa=Muslim](https://reader034.fdocuments.net/reader034/viewer/2022050210/5f5c823a9140f377e0168fc1/html5/thumbnails/5.jpg)
Landforms
• Sahel – Mainly flat with some
plateaus
– Steppe region: 3,000 miles wide
– East of this area: the Horn of Africa
– Little rainfall in this region
– Good for herding livestock

Water Systems
• Due to the dryness of this area, droughts are common.
• Lake Chad
– Once the second=largest wetland in Africa
– 3 rivers feed into it:
• Chari, Logone, Yobe
– Today: due to droughts, much of the rivers and lake is drying up

Water Systems
• Lake Volta
– Ghana
– One of the largest human-made lakes
– Multiple countries share the river systems that lead into this lake
– Good for irrigation and fisheries
• Negative consequences??

Water Systems
• Niger River – One of the major rivers in
western Africa
– Means of transportation
• Delta-triangular-shaped section of land formed as waters of a river slow down and split into many channels as they deposit sand and silt
![Page 10: Chapter 20: The Transition Zone - anderson1.org€¦ · Landforms •Not only is the transition zone a physical divider in Africa, it is also a cultural divider –North Africa=Muslim](https://reader034.fdocuments.net/reader034/viewer/2022050210/5f5c823a9140f377e0168fc1/html5/thumbnails/10.jpg)
Water Systems
• Senegal River – Many people live
along the banks
– Dams were built to help people better use the resources
• Blue and White Nile Rivers – Feed into the Nile
River of Egypt

History and Government • 9000-4000 BC, Sahara was actually filled with
water…not like the desert region it is today
• Many people settled here and thrived by domesticating plants and animals
• But when the climate shift happened, most people moved south to set up new homes
![Page 14: Chapter 20: The Transition Zone - anderson1.org€¦ · Landforms •Not only is the transition zone a physical divider in Africa, it is also a cultural divider –North Africa=Muslim](https://reader034.fdocuments.net/reader034/viewer/2022050210/5f5c823a9140f377e0168fc1/html5/thumbnails/14.jpg)
History and Government
• Egyptian civilization ruled over much of the area from 2000-1000 BC
• Kush civilization was growing in present-day Sudan – Took over the Egyptian civilization from 2000 to 1500
BC – Moved south and controlled that area until about 300
AD
• Axum was a trading empire in Ethiopia and ruled from 100-700 AD – Attacked Kush civilization
