Yintoni efana ngayo iGrand Canyon kunye nesiXeko saseNew York?

Ngalo lonke ixesha ndisiya eNew York ndiye ndichukumiseke – kwaye ndihlala ndisonganyelwa – zizakhiwo ezinde kunye nobomi obuphithizelayo. Ukuma ngaphantsi kwesakhiwo esiziimitha ezingama-300 ubude okanye ujonge ngaphezulu komgangatho waso wokuphonononga, isixeko sinokuba lihlathi lasezidolophini elijonge phezulu okanye isixeko sokudlala esibenyezelayo esibengezela ezantsi. Yiba nomfanekiso-ngqondweni wokutsiba ukusuka kwindawo ephakamileyo yesiXeko saseNew York ukuya kubunzulu beGrand Canyon, i-1800 m ukuhla.

Ubukhulu bezi mimangaliso zenziwa ngabantu kunye nendalo buye baphefumlela amagcisa, izazi ngendalo, nezazinzulu kangangeenkulungwane. Umboniso wamva nje ngu Gus Petro Ucinga ukuba isixeko simi phakathi kweentlambo kunye neencopho zeGrand Canyon - kodwa kuthekani ukuba bendikuxelele ukuba kukho umwonyo ophindwe kabini ngobukhulu obusele useNew York? Akukho mfuneko ye-photoshop apha, i Hudson Canyon yi-740 km ubude kunye ne-3200 m ubunzulu kunye neemayile nje phantsi koMlambo i-Hudson kwaye ngaphantsi kolwandle oluluhlaza okwesibhakabhaka...

Ishelufu ye-Mid-Atlantiki iphawulwe ngemiwonyo kunye neentaba zolwandle, nganye inomtsalane njengeGrand Canyon kwaye iyaphithizela njengesiXeko saseNew York. Imibala eqaqambileyo kunye neentlobo ezizodwa zihamba emgangathweni okanye zihamba ngenqanawa ebunzulwini. Ukusuka eVirginia ukuya kwisiXeko saseNew York kukho ishumi lemiwonyo enzulu yolwandle ezele bubomi - imiwonyo elishumi esikhokelela komnye wemibhiyozo yethu yeminyaka eli-10.

Imiwonyo ephuma eVirginia naseWashington, DC- eNorfolk, eWashington, kwaye Accomac Iikhanyoni – babe neminye imizekelo esemazantsi yeekorali zamanzi abandayo kunye nezilwanyana ezinxulumene nazo. Iikorale ngokuqhelekileyo zinxulunyaniswa namanzi ashushu, ashushu. Iikorali zamanzi anzulu zibaluleke kakhulu kwaye zibamba iintlobo ngeentlobo zeentlobo ezahlukeneyo njengabazala babo baselwandle. I Norfolk umwonyo onzulu ohamba amanzi iye yanconywa njengendawo ekhuselweyo yaselwandle amaxesha ngamaxesha, umzekelo oqhelekileyo wendlela esiphatha ngayo ubutyebi bethu baselwandle. Yayiyindawo yokulahla inkunkuma eqhuma kabini ngokuphindwe kabini kwaye kungoku nje iphantsi kwesoyikiso sophando lwenyikima.

Ukuya ngasemantla kusizisa kwindawo Baltimore Canyon, iphawuleka ngokuba yenye yeemethane ezintathu kuphela zokusepha ecaleni kweshelufu ye-Mid-Atlantic. Iisep zeMethane zidala imeko-bume engqongileyo ebonakalayo neyemichiza ekhethekileyo; indawo apho ezinye iimbaza noononkala zifaneleka kakuhle. I-Baltimore ibalulekile kubuninzi bayo bobomi be-coral kwaye isebenza njengeendawo ze-nursery kwiintlobo zorhwebo.

Le miwonyo enzulu yolwandle, njenge Wilmington kwaye Spencer Iikhanyoni, ziindawo zokuloba ezinemveliso. Ukwahluka kunye nobuninzi obuphezulu beentlobo zenza indawo efanelekileyo yokuloba kunye norhwebo. Yonke into ukusuka koononkala ukuya ityhuna kunye nookrebe inokulotywa apha. Njengoko iyindawo yokuhlala ebalulekileyo kwiintlobo ezininzi zezinto eziphilayo, ukukhusela imiwonyo ngamaxesha onyaka wokuzala kunokwenza lukhulu kulawulo lokuloba.  Tom's Canyon Complex – uthotho lwemiwonyo emincinci emininzi – ikwakhethelwe amabala ayo okuloba anomtsalane.

Njengoko ziintsuku nje ezimbalwa emva kweHalloween, oku bekungayi kuba sisithuba esikhulu ngaphandle kokukhankanya into emnandi - bubblegum! Ikorale, oko kukuthi. Olu hlobo lubizwa ngokuba yi-evocatively lufunyenwe yi-NOAA yokuhlola ulwandle olunzulu Veatch kwaye Gilbert Iikhanyoni. UGilbert wayengakhethwanga ekuqaleni ngenxa yokuba neentlobo ezininzi zeekorale; kodwa uhambo lwe-NOAA kutshanje lufumene into eyahlukileyo. Sifunda ngalo lonke ixesha ukuba zininzi kangakanani iiyantlukwano ezifumaneka kwinto esicinga ukuba ziindawo ezingenabomi zomgangatho wolwandle. Kodwa sonke siyayazi into eyenzekayo xa sicinga!

Ukulandela lo mzila wemiwonyo ngowona mkhulu kuzo zonke - i Hudson umwonyo onzulu ohamba amanzi. Inobunzima obuziikhilomitha ezingama-740 ubude kunye neemitha ezingama-3200 ubunzulu, bunzulu ngokuphindwe kabini kuneGrand Canyon eyothusayo kunye nendawo yokuzimela yezilwanyana kunye nezityalo - ukusuka kwizidalwa ezizinzile ezinzulwini ukuya kwiminenga enomtsalane kunye namahlengesi ahamba ngenqanawa kufutshane nomphezulu. Njengoko igama layo lisitsho, lulwandiso lwenkqubo yoMlambo i-Hudson- ityhila unxibelelwano oluthe ngqo nolwandle kumhlaba. Abo bayaziyo baya kucinga ngeendawo ezininzi zokuloba ityhuna kunye nolwandle olumnyama. Ngaba bayazi ukuba i-Facebook, i-imeyile, kunye ne-BuzzFeed zonke zivela kwi-Hudson Canyon? Lo mmandla ongaphantsi kolwandle ungumbindi weentambo zonxibelelwano zefiber-optic ezisiqhagamshela kwihlabathi elibanzi. Into esiyibuyisela kuyo ingaphantsi kweenkwenkwezi - ungcoliseko kunye nenkunkuma zihanjiswa kwimithombo esemhlabeni kwaye ihlale kule miwonyo inzulu kanye ecaleni kweentlobo zazo ezahlukeneyo zeentlobo.

I-Ocean Foundation ibhiyozela iminyaka elishumi yethu kwisiXeko saseNew York kule veki - into esinethemba lokuyibhiyozela kungekudala kukhuseleko lwemiwonyo engaphantsi kolwandle. Ukuxhasa ukuzala kweentlanzi, iindawo ezibalulekileyo zokugcinwa kwezilwanyana, izilwanyana zaselwandle ezinkulu nezincinci, kunye nenkitha yezidalwa eziziintlobo ngeentlobo, le miwonyo sisikhumbuzo esimangalisayo sokwahluka kobomi emanzini ethu. Izakhiwo eziphakamileyo ezijonge phezulu kwizitrato zaseNew York zilinganisa imiwonyo emikhulu ekumgangatho wolwandle. Isiphithiphithi sobomi kwizitrato zaseNew York - izibane, abantu, amatikiti eendaba, iifowuni kunye neetafile eziqhagamshelwe kwi-intanethi - nazo zilinganisa ubomi obuninzi phantsi kolwandle kwaye zisikhumbuza ukuba zibaluleke kangakanani kubomi bethu bemihla ngemihla emhlabeni.

Ke iGrand Canyon kunye nesiXeko saseNew York zifana ngantoni? Zizizikhumbuzo ezibonakala ngakumbi zendalo kunye nemimangaliso eyenziwe ngabantu ephantsi kwamaza.
