Ngaba uyazi igama leyona nxalenye encinci yeSiteshi seNgesi?

Kukho uqobo olukhethekileyo, olubizwa ngamazwe angamaNgesi abizwa ngokuba yi-Dover. Ngaphantsi kwezantsi kwayo ihamba i-Eurotunnel. Le yiNgqungquthela eyaziwayo yesiNgesi, emele indawo engummangaliso. Kwaye kunomdla nje kuphela kwimimandla yayo, kodwa nangenxa yemvelaphi yayo. Liliphi igama leyona nxalenye encinci yeSiteshi seNgesi? Ngokuphathelele indawo yakhe kunye neempawu ziya kuxelwa kule nqaku.

Indawo yesimo seNgqungquthela yesiNgesi

Uxinzelelo ludibanisa i-Atlantic Ocean kunye noLwandle oluMntla. Iikhilomitha ezili-578 ubude bayo, ububanzi kwicala lasentshonalanga - 250 km, empuma-130 km. Ubunzulu obuncinci buyi-23.5 yamitha.

Kubalulekile ukuba uqaphele ukuba i-tunnel ekhethekileyo yakhiwe phakathi kweedolophu zaseCalais kunye neDover (njengenxalenye encinci yeThaneli ibizwa, siya kufumana apha ngezantsi).

Ngaphezu kweekhilomitha ezingama-52 (i-38 km kwendlela ehamba ngqo phantsi koxinzelelo) ubude bayo.

Izikhulu eziphambili zi: Le Havre, ePortsmouth, eCherbourg naseSouthampton. Kukho iziqithi, ezona zikhulu kunazo zonke ezikulo lonxweme lwe-Great Britain (i-White Island) kunye nommandla wonxweme waseFransi (iIs Channel Islands).

Imbali yokwakhiwa kwesi siqithi

KwiRoma yaseRoma, le nto yayibizwa ngokuthi i-Oceanus Britannicus, eguqulela ngokuthi "uLwandle lwaseBritani". Ekupheleni kwexesha, waba ngumncinci. Kwixesha lama - Victorian, wayenalo igama - "uLwandle lwaseBritani", kwaye nanamhlanje abahamba ngomkhumbi bayabiza le ndawo nje "ngomkhonto" (Umkhwa).

Iingqikithi zendawo yeNgesi YaseTshayina kwimihla yakudala yayingumhlaba ophantsi (into efana neNetherlands). Emva koko i-surface level sea seaqala ukunyuka kwaye izalise iinqaba ezinkulu ngamanzi olwandle. Le ndawo yaba yinto engaphantsi kwesi sikhundla esele sikhona esasahlukanisa iBrithani enkulu ukusuka kwilizwekazi elikhulu.

Ngaphambi kokuba siyazi ukuba yintoni inxalenye encinci yeSiteshi seNgesi, qwalasela enye ingcamango yemvelaphi yale shaneli.

Inguqulelo entsha

Ngaphezulu kweminyaka engama-20 eyadlulayo kwakukho enye, kunokwenzeka ukuthetha, ingcamango yentlekele yokuphuhliswa kweemeko. Uninzi lwabantu baseGeographer baqonda ukuba lukhulu kakhulu.

Kwiphephancwadi leNdalo, inqaku lenzululwazi lishicilelwe yiNzululwazi yase-London evela kwi-Imperial College, eyayitsho ukuba ukuhlukana kwe-UK kunye neFransi kwakhiwa ngenxa yezinye iinkqubo zemvelo. Bakholelwa ukuba imbangela yokuzalwa kweThaneli yayiyi-flow of catastrophic flow of water from echibi elikhulu, eyakhiwa ngenxa ye-confluence ye-Rhine ne-Thames kwixesha elibukhali.

Inhloko yalezi zifundo uSanjeev Gupta yathi ngaphezu kweminyaka engama-420 eyadlulayo, iBrithani neFransi zadibaniswa yi-Veld-Artois. Le ngqungquthela ekhethiweyo, ubude bayo bufikelela kwiimitha ezili-180 kwindawo yomda obunombuzo, kwaye inxalenye engasentshona yahlala phantsi. Amanzi avela kwiRhin, i-Thames kunye neminye imilambo ihamba apha ngaphesheya kweLwandle oluMntla.

Kwaye xa amaqabunga ekhuselekileyo avala uMlambo oMntla, amanzi emlambo aqala ukuqokelela kwindawo efihliweyo, ekwakheni ulwandle olukhulu, olwakhutshwa yimilambo kunye namaqhwa aqhaqhaqhaqha.

Liliphi igama leyona nxalenye encinci yeSiteshi seNgesi, indawo yaso

Le ndawo iphakathi komama wengxenye yeYurophu kunye nesiqithi saseBritain.

Le yindawo enhle kunye neendawo ezintle, apho ngosuku olukhanyayo olusondeleyo unokubona izakhiwo zikhona ngaphesheya kwenkqantosi, kwaye ebusuku zibona izibane ezikhanyayo.

Inxalenye encinane kunazo zonke zesiNgesi seTranshini ibizwa ngokuba yi-Pas-de-Calais okanye i-Dover. Ububanzi bayo buyi 32 km kuphela. Itholakala kuphela phakathi kwesixeko saseFransi saseCalais kunye nesango lesiNgesi sase Dover. Umkhumbi weenqanawa uwela i-Pas-de-Calais kwiiyure eziyi-1,5-2. Kule ndawo, i-Eurotunnel yakhiwe phantsi kwamanzi.

Inkcazelo

Kukho inqaku kwi geology - i-mega-flux. Zichaza iziganeko ezenzeke kwiminyaka engama-500 edlulileyo kwintsimi ngoku emela umqobo wamanzi phakathi kweziqithi zaseBrithani nakwilizwekazi. Kuthetha malunga nesiNgesi.

NgesiFrentshi, isiTshayina saseNgesi sithetha "umkhonto". E-UK ibizwa ngokuba yiNgesi YesiNgesi. Ubude bayo bu malunga ne-560 km, kwaye ububanzi obude bubungama-240 km. Phantse ububanzi beekhilomitha ezingama-34 yinxalenye encinci yeSingesi.

Iinkcukacha ezinqwenelekayo malunga nokuxhamla ngokubanzi

• Ngexesha leMfazwe Yehlabathi yokuqala, umgodi we-Heard Deep, ephantsi kweNgesi YesiNgesi, yayisetyenziswa yiBrithani ukulahla izixhobo zamakhemikhali. Kwaye emva kweMfazwe Yehlabathi Yesibili (1941-1945), amaJamani ayekhukhulwa apha. Ukususela ngo-1946 ukuya ku-1973, i-isotophi e-radioactive yangcwatywa apha.
• Umshukumi wokuqala wembali yoluntu, ewela iNgesi YesiNgesi, nguMateyu Webb. Le ndlela yokubhukuda ngo-1875 yahlala malunga neeyure ezingama-22 (ngaphandle kwemizuzu eyi-15).
• Izitimela ze-Eurotunnel i-Eurostar ngesivinini seekhilomitha ezili-160 ngeyure.
• Kwesinye seziqithi ze-strait enegama elithi Sark (i-Normandy Islands), i-feudalism yahlala ngo-2008. Isiqithi kude kube ngulo mzuzwana kwalawulwa libhunga labadala. Esi siqithi sokugqibela eYurophu kunye nohlobo lolawulo.
• Kwisiteshi seNgesi kukho i-eel enkulu, ubunzima bayo bube ngaphezu kweekhilogram eziyi-100, ubude bufikelela kumitha amathathu.
• Umzila kuphela osebenza kwi siqithi saseAlderney (Channel Islands), eyakhiwa ngo-1847. Ubude balo bu-3 km. Isebenza kuphela ehlobo kwaye kuphela ngeveki neeholide.

Safunda igama leyona nxalenye encinci yeSiteshi seNgesi, safumanisa imbali yokuvela kwe-strait kwaye saqonda ukuba le ndawo ingenye yezona ndawo zincomekayo zomhlaba.
