I-geology yommandla uyila ngaphezulu kwezigidi zeminyaka kwiplanethi yethu. Kubangelwa ziziphene, iinyikima, ukhukuliseko lomoya oluqhubekayo, amaza amakhulu, ukutsala, intlenga, njl. Ziinkqubo zejoloji ezithi zivelise iifom zejografi esizibonayo njengesiphumo namhlanje. Iimilo ezinjengeebheyi, iintaba kunye neekapisi.
Ngokuqinisekileyo uwubonile umsantsa kwaye ukhe wacinga ngendlela awenziwe ngayo. Ngaba uyafuna ukwazi ukuba yintoni i-gulf kwaye yintoni inkqubo yokuyilwa kwayo?
Inkcazo
KwiGulf of cadiz
Umsantsa luphawu lwejografi olubonakaliswa ngokuba inxalenye enkulu yolwandle okanye yolwandle eziswe emhlabeni. Ime phakathi kweentloko ezimbini okanye iipeninsula ezimbini. I-gulf ihlala inzulu kakhulu kwaye ibaluleke kakhulu kuqoqosho ukusukela, ngenxa yendawo yabo kunye nokuma komhlaba, bakhonza ukukhusela unxweme kumaza amakhulu. Oku kuthanda ulwakhiwo lwamazibuko kunye neendawo zokunyusa uqoqosho lonxweme.
Igama elithi gulf lihlala lididekile kunye neebheyi okanye ukungena, nangona kunjalo, azifani.
Inkcazo ye-bay kunye ne-cove
Bay
I-bay yindawo engena elwandle okanye echibini leyo phantse ujikelezwe ngokupheleleyo ngumhlaba, ngokungafaniyo nomsantsa, ngaphandle kwesinye seziphelo zawo. Amatheku akhiwa kwiminyaka edlulileyo ngenxa yokukhukuliseka konxweme kwaye athathelwa ingqalelo ziijografi njengobungqina bemimandla eselunxwemeni. Amanzi ngokuqhubekayo abetha elunxwemeni kwaye ayabumba ukutyhubela iminyaka ukwenza olu hlobo lwe-morphology.
Unokuthi i-bay ichasene nosiqithi. Ngelixa usingasiqithi sisiqwenga somhlaba esijikelezwe ngamanzi, ngaphandle kokuphela kwesinye isiphelo, ichweba sisiqwenga samanzi esijikelezwe ngumhlaba, ngaphandle kokuphela kwesinye.
Umntu usebenzisa ithuba leebheyi, njengezikhewu, kulwakhiwo lwamazibuko ukonyusa uqoqosho lwendawo.
Kwelinye icala, kwijografi i-cove ichazwa njengendawo egudle unxweme eyakhiwe ngamanzi angenisa imilo ejikelezayo kwaye igcinwe ngumlomo omxinwa, odla ngokwenziwa ngamatye.
Umahluko phakathi kwegulf, bay kunye ne-Cove
Ensenada
Njengoko la magama eqhele ukudideka, iJografi iwusetile umahluko phakathi kwawo. I-gulf, i-bay kunye ne-inlet, ngaphandle kokuba ne-morphologies efanayo, yabelana ngumahluko kubungakanani nakwinzulu. Ngesi sizathu, i-gulf yeyokuqala ngobukhulu obukhulu kunye nobunzulu, ilandelwa ngamachaphaza, incinci kwaye incinci kwaye iphela ngokungena.
Iindawo zokungena zishiye indawo yokugqibela, ukusukela kuncinci kakhulu kwaye kungaphantsi, endaweni yokuba zilungiswe ngonxweme, ziguqulwa ngamatye aphumela elwandle ukusuka kulwandle.
Ezi zinto zintathu ze-geomorphologies ezinje ngokufanayo kukuba zenzelwe ukwakhiwa kwamazibuko ukuphucula uqoqosho lwendawo. Izibuko linokwakhiwa ngokulula, kuba amanzi abuthathaka kwaye ezi ndlela ziyabakhusela ekunyukeni komsinga wamanzi.
Ukongeza, ubuhle ababonelelayo ngenkangeleko, ngamanqaku abalulekileyo kuqoqosho lwehlabathi, Ayisiyiyo eyokwakhiwa kwamazibuko kuphela, kodwa ikwacwangciselwe ukuba ibe ziindawo apho kuthengiswa izinto zorhwebo ngomlinganiselo omkhulu, bobabini abo bafika bevela kwilizwe elithile nabo bahambayo, bahlala befunwa kwiindawo zabakhenkethi, njl.
Iindawo zokungena, zincinci ngobukhulu nangobunzulu, azisetyenziswa njengokwakhiwa kwamazibuko, nangona ngamanye amaxesha kwakhiwa ii-dock ezincinci, zisetyenziselwa ukuba zisetyenziswe njengeelwandle, enkosi kwinto yokuba amatye ayawavala amanzi kwaye awavumeli ukuba abenamaza okanye imisinga enamandla.
Ezona gulf zaziwayo kwihlabathi
Nje ukuba ufunde inkcazo ye-gulf kunye numahluko ngee-bay kunye ne-inlets, lixesha lokuba wazi ezona ndawo zibalulekileyo nezaziwayo emhlabeni. Zininzi izithuba zomhlaba, kodwa ezona zibalulekileyo kwinqanaba elikhulu yiGulf of Mexico, iGulf of Alaska kunye neGulf of St. Lawrence.
KwiNxweme yaseMexico
IGulf of Mexico imi phakathi konxweme lwaseMexico (kwiphondo laseTamaulipas, eVeracruz, eTabasco, eCampeche naseYucatán), unxweme lwaseUnited States (eFlorida, Alabama, Mississippi, eLouisiana naseTexas) kunye Unxweme oluvela kwisiqithi saseCuba (kwinxalenye esempuma yomsantsa, kwindawo yayo eya kuLwandlekazi lweAtlantic).
KwiGulf of alaska
IGulf of Alaska ibandakanya indawo egobileyo yoLwandlekazi lwePasifiki kunxweme olusemazantsi eAlaska, lubotshwe ngasentshona yiAlaska Peninsula kunye nesiqithi iRaak, nakwimpuma yiAlexander Archipelago eGlacier Bay. IGulf of Alaska inkulu kakhulu kubunzulu kunye nobubanzi kangangokuba ithathwa njengolwandle.
Ubuninzi bemvula eqokelelwa ngexesha leemvula kwiPasifiki yoMntla-ntshona kwenzeka kweli gophe. Unxweme luqhutywa kakhulu kwaye luneminyango enzulu. Kuwo wonke umntu onokuyibona, ungonwabela imihlaba yehlathi, iintaba kunye neqabana zomkhenkce ezivela elunxwemeni.
Owona mlambo uphambili uwela umsantsa ngulo weAlaska. Yimisinga eyinxalenye yebhanti yokuhambisa, ifudumele isimilo kwaye iqukuqelela emantla.
Ngenxa yokuma kwayo kunye nobume bayo, iGulf of Alaska ivelisa isaqhwithi ngokuqhubekayo. Le meko inyuka rhoqo kunye nokuqina kwiindawo zeArctic Circle, apho izivunguvungu zibangelwa likhephu elininzi kunye nomkhenkce. Ezininzi zezi zivunguvungu ziya emazantsi okanye kunxweme lwaseBritish Columbia, eWashington naseOregon.
IGulf of Saint Lawrence
Lo msantsa ubekwe kwimpuma yeKhanada kwaye uqhagamshela kuLwandlekazi lweAtlantic. Umda omkhulu. Umlambo iSt. Lawrence uqala kwiChibi iOntario kwaye, ngeyona ndawo inkulu elunxwemeni emhlabeni, ungena kweli gophe.
Ngolu lwazi uya kuba nakho ukwazi kakuhle umahluko phakathi kwe-gulfs, bay kunye ne-inlet kwaye wazi ezona ndawo zibalulekileyo emhlabeni.
