where does the source of the amazon river start
Amazon River The headwaters of the Apurímac River on Nevado Mismi had been considered for nearly a century as the Amazon’s most distant source, until a 2014 study found it to be the Cordillera Rumi Cruz at the headwaters of the Mantaro River in Peru.[4] The Mantaro and Apurímac confluence, and with other tributaries form the Ucayali River, which in turn confluences with the Marañón River upstream of Iquitos, Peru, to form what countries other than Brazil consider to be the main stem of the Amazon. Brazilians call this section the Solimões River above its confluence with the Rio Negro[5] to form what Brazilians call the Amazon at the Meeting of Waters (Portuguese: Encontro das Águas) at Manaus, the river's largest city.
Nile The Nile (Arabic: النيل‎) 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]
