Nigeria
Rivers and Lakes of Nigeria
About two-thirds of Nigeria lies in the watershed of the Niger River, which empties in to the Atlantic at the Niger Delta, and its major tributaries: the Benue in the northeast, the Kaduna in the west, the Sokoto in the northwest, and the Anambra in the southeast.
Religion in Nigeria
Religious affiliation in Nigeria is strongly related to ethnicity, with rather distinct regional divisions between ethnic groups. The northern states, dominated by the Hausa and Fulani groups, are predominantly Muslim while the southern ethnic groups have a large number of Christians. In the southwest, there is no predominant religion.
Climate of Nigeria
As in most of West Africa, Nigeria's climate is characterized by strong latitudinal zones, becoming progressively drier as one moves north from the coast. Rainfall is the key climatic variable, and there is a marked alternation of wet and dry seasons in most areas.
