Which Nigerian landforms are included in the uplands of western Africa?

The interior uplands of western Africa are composed of ancient crystalline rocks, and several prominent Nigerian landforms are included in this region. These include:1

• Jos Plateau: Located in central Nigeria, this plateau consists of extensive lava surfaces dotted with numerous extinct volcanoes and is characterized by high plains with broad, shallow valleys.23
• Adamawa region: This area, which extends into Cameroon, includes significant volcanic uplands.14
• Cameroon Highlands: While primarily along the border with Cameroon, these highlands contain the highest points in Nigeria, such as the Gotel Mountains and the Shebshi Mountains.21

Additionally, other eroded surfaces like the Udi-Nsukka Plateau rise abruptly above the surrounding plains, contributing to the varied topography of the region.2
