Aflat \u00een centrul Australiei, r\u00e2ul Finke este considerat de cercet\u0103tori cel mai vechi r\u00e2u care curge continuu pe P\u0103m\u00e2nt, potrivit DailyGalaxy<\/a><\/span>.<\/p>\n

Oamenii de \u0219tiin\u021b\u0103 estimeaz\u0103 c\u0103 are \u00eentre 300 \u0219i 400 de milioane de ani, ceea ce \u00eenseamn\u0103 c\u0103 a \u00eenceput s\u0103 curg\u0103 cu mult \u00eenainte de apari\u021bia dinozaurilor.<\/p>\n

Un r\u00e2u mai vechi dec\u00e2t mun\u021bii pe care \u00eei traverseaz\u0103<\/h2>\n

Cunoscut sub numele de Larapinta \u00een limba indigen\u0103 Arrernte, r\u00e2ul Finke str\u0103bate MacDonnell Ranges, un peisaj accidentat format \u00een timpul Orogenezei (proces tectonic de formare a lan\u021burilor muntoase) Alice Springs.<\/p>\n

Ceea ce \u00eel face remarcabil este traseul s\u0103u transversal, care taie direct forma\u021biuni de roc\u0103 dur\u0103, \u00een loc s\u0103 le ocoleasc\u0103.<\/p>\n

Acest tipar neobi\u0219nuit sugereaz\u0103 c\u0103 r\u00e2ul exista \u00eenainte ca mun\u021bii s\u0103 se ridice \u0219i \u0219i-a men\u021binut cursul pe m\u0103sur\u0103 ce relieful s-a \u00een\u0103l\u021bat lent.<\/p>\n

Geomorfologul Victor Baker explic\u0103 fenomenul prin conceptul de \u201eanteceden\u021b\u0103\u201d, c\u00e2nd r\u00e2ul erodeaz\u0103 \u00een jos \u00een timp ce terenul se ridic\u0103.<\/p>\n

Stabilitatea tectonic\u0103 i-a asigurat supravie\u021buirea<\/h2>\n

Stabilitatea geologic\u0103 a Australiei a jucat un rol esen\u021bial \u00een conservarea traseului antic al r\u00e2ului.<\/p>\n

Spre deosebire de continentele marcate de cutremure frecvente sau de glacia\u021biuni, Placa Australian\u0103 a r\u0103mas relativ neschimbat\u0103 timp de sute de milioane de ani.<\/p>\n

Geologul Ellen Wohl subliniaz\u0103 c\u0103 multe r\u00e2uri str\u0103vechi au disp\u0103rut din cauza activit\u0103\u021bii vulcanice, glacia\u021biunilor sau schimb\u0103rilor topografice majore.<\/p>\n

Absen\u021ba unor astfel de evenimente a permis r\u00e2ului Finke s\u0103 evite \u00eengroparea, devierea sau eroziunea masiv\u0103.<\/p>\n

Dovezile izotopice confirm\u0103 vechimea<\/h2>\n

Pentru a sus\u021bine v\u00e2rsta estimat\u0103 a r\u00e2ului, cercet\u0103torii au folosit datarea cu izotopi radioactivi \u0219i analize de eroziune.<\/p>\n

De-a lungul unor perioade uria\u0219e de timp, apa las\u0103 semn\u0103turi chimice \u00een rocile expuse, \u00eenregistr\u00e2nd interac\u021biunea lor cu aerul \u0219i eroziunea.<\/p>\n

Studii citate de Live Science indic\u0103 faptul c\u0103 terenul din jur s-a format \u00een aceea\u0219i perioad\u0103 tectonic\u0103, acum 300-400 de milioane de ani.<\/p>\n

Aceast\u0103 concordan\u021b\u0103 \u00eent\u0103re\u0219te ipoteza c\u0103 r\u00e2ul Finke este cel mai vechi sistem fluvial supravie\u021buitor care \u00ee\u0219i urmeaz\u0103 \u00eenc\u0103 traseul original.<\/p>\n","protected":false},"excerpt":{"rendered":"
