Where is Nigeria's tectonic plate?

Nigeria is primarily situated on the West African Craton, which is part of the larger African tectonic plate. This craton is a stable portion of the continental crust that has remained relatively unchanged for billions of years. The country is also influenced by the boundary interactions with the surrounding plates, including the boundary with the Eurasian Plate to the north and the South American Plate to the west.
