(i) The plains of Hausa land, which has an average elevation of 75Cm and

(ii) the Jos plateau, which is the highest platform with an average elevation of 180Cm.

The Eastern Highlands lie within Nigeria and Cameroon border fringe. This highland covers the highest zone in Nigeria and it consists of the Obudu Plateau (120Cm), Oban hills (120Cm), the Biu Plateau (800-1200m) etc.

The Western Uplands cover One-tenth of the country area. Most of the upland area lies between 300-600 metres. The highest part of the western upland is the Idanre Hills, which cover about 1000 metres above sea level.
