what is the source of the river niger
Niger River The Niger River (/ˈnaɪdʒər/; French: (le) fleuve Niger, pronounced [(lə) flœv niʒɛʁ]) is the principal river of West Africa, extending about 4,180 km (2,600 mi). Its drainage basin is 2,117,700 km2 (817,600 sq mi) in area.[3] Its source is in the Guinea Highlands in southeastern Guinea. It runs in a crescent through Mali, Niger, on the border with Benin and then through Nigeria, discharging through a massive delta, known as the Niger Delta or the Oil Rivers, into the Gulf of Guinea in the Atlantic Ocean. The Niger is the third-longest river in Africa, exceeded only by the Nile and the Congo River (also known as the Zaïre River). Its main tributary is the Benue River.
Nile The Nile River (Arabic: النيل‎, Egyptian Arabic en-Nīl, Standard Arabic an-Nīl; Coptic: ⲫⲓⲁⲣⲱ, P(h)iaro; Ancient Egyptian: Ḥ'pī and Jtrw; Biblical Hebrew: הַיְאוֹר‬, Ha-Ye'or or הַשִׁיחוֹר‬, Ha-Shiḥor) is a major north-flowing river in northeastern Africa, and is commonly regarded as the longest river in the world,[1] though some sources cite the Amazon River as the longest.[2] The Nile, which is 6,853 km (4,258 miles) long, is an "international" river as its drainage basin covers eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of the Sudan and Egypt.[3] In particular, the Nile is the primary water source of Egypt and Sudan.[4]
