Africa · Volcanic highland
Ethiopian Highlands
- Countries
- Ethiopia, with a fringe in Eritrea.
- Length
- A highland mass, roughly 1,000 km north–south. Not a single linear chain.
- Orientation
- Massif, cut by rift faults trending northeast–southwest.
- Mountain type
- Volcanic highland
- Plates
- African plate, on the East African Rift near the Afar triple junction. Divergence, not a fold-mountain collision.
- Highest peak
- Ras Dashen, 4,550 m. Exam-safe textbook figure.
- Rivers that rise here
- Blue Nile from Lake Tana, Atbara, and the Awash, which never reaches the sea.
- Climate and rain shadow
- Orographic rain feeds the Nile flood. The highlands are the ‘water tower’ of the Nile, not its longest headstream.
Mains use
Volcanic-rift highland, not a fold range. Link to Nile international disputes only as the source of the Blue Nile’s water.
