Mtsinje wa Nile wodziwika nthawi zonse amakhulupirira kuti ndiwotalika kwambiri padziko lapansi, koma bwanji ngati sichoncho? Kuyeza mitsinjeyi sikophweka momwe imamvekera, ngakhale kwa ojambula mapu a hydrographic chifukwa zimatengera zinthu zosiyanasiyana: muyeso womwe ukugwiritsidwa ntchito, kumene mtsinje wina umayambira pomwe wina umatha (popeza mitsinje yambiri imakumana ndi mitsinje), kutalika kwake kapena voliyumu.

Kuti achite kafukufukuyu, asayansi adayenda milungu iwiri kuti akwaniritse kutalika kwake pafupifupi mita 5.000. Mpaka nthawiyo, gwero la Amazon linali litakhazikitsidwa mu chigwa cha Carhuasanta ndi phiri lotsekedwa ndi chipale chofewa la Mismi, koma a Geographical Society of Lima adatsimikizira kudzera pazithunzi za satellite kuti Mtsinje wa Amazon unayambira mumtsinje wa Apacheta (Arequipa), chifukwa chake mtsinje wautali kwambiri padziko lonse lapansi, woposa Mtsinje wa Nailo pafupifupi makilomita pafupifupi 400.

Ndani ali ndi chifukwa?

Asayansi ambiri akupitilizabe kunena kuti Mtsinje wa Nile ndiwutali kwambiri padziko lonse lapansi. Ndani ali ndi chifukwa? Sizikudziwika bwinobwino chifukwa nkhaniyi idakalipobe. Ngakhale, titapatsidwa m'lifupi ndi kuchuluka kwake kwakukulu, mwina kungakhale kofunikira kudalira Amazon.
