Iyini iGulf?

Ukwakheka komhlaba kuyakheka ngaphezulu kwezigidi zeminyaka emhlabeni wethu. Kubangelwa amaphutha, ukuzamazama komhlaba, ukuguguleka komoya okuqhubekayo, amagagasi anamandla, ukudonsa, inzika, njll. Kuyizinqubo zokwakheka komhlaba eziveza amafomu wezwe esiwabona njengomphumela namuhla. Izimo ezinjengamabhayi, izintaba namakhanda.

Impela ulibonile igebe futhi uke wacabanga ukuthi lakhiwa kanjani. Ngabe ufuna ukwazi ukuthi yini i-gulf futhi iyini inqubo yokwakheka kwayo?

Incazelo

I-gulf isici sendawo esibonakala ngokuba ne- ingxenye enkulu yolwandle noma yolwandle elethwe emhlabeni. Itholakala phakathi kwamakhanda amabili noma izinhlonhlo ezimbili. Igebe livame ukujula kakhulu futhi libaluleke kakhulu kwezomnotho ngoba, ngenxa yendawo elikuyo nesimo sendawo, basebenzela ukuvikela ugu emagagasini amakhulu. Lokhu kuvuna ukwakhiwa kwamachweba kanye nezindawo zokukhuphula izinga lokukhulisa umnotho wasogwini.

Igama elithi gulf livame ukudideka namatheku noma okungena, noma kunjalo, awafani.

Incazelo ye-bay ne-cove

Itheku itheku elivela olwandle noma echibini lelo cishe uzungezwe umhlaba ngokuphelele, Ngokungafani neGulf, ngaphandle kweyodwa yemikhawulo yayo. Amatheku akhiwa eminyakeni edlule ngenxa yokuguguleka kogu futhi athathwa ngabezokuma komhlaba njengokufinyeleleka kogu. Amanzi aqhubeka eshaya ugu futhi alubumba eminyakeni edlule ukudala lolu hlobo lwe-morphology.

Ungasho ukuthi itheku liphambene nenhlonhlo. Ngenkathi i-peninsula iyisiqephu somhlaba esizungezwe ngamanzi, ngaphandle kokukodwa, itheku liyisiqeshana samanzi esizungezwe umhlaba, ngaphandle kokukodwa.

Umuntu usebenzisa ngokunenzuzo amatheku, njengamagebe, ekwakhiweni kwamachweba okwandisa umnotho wendawo.

Ngakolunye uhlangothi, kwezokuma komhlaba i-cove ichazwa njengesici sendawo esogwini esakhiwe yindawo yokungena yamanzi eyakheke ngendlela eyindilinga futhi evikelwe ngomlomo omncane, ovame ukwenziwa ngamatshe.

Umehluko phakathi kwe-gulf, bay ne-cove

Njengoba la magama evame ukudideka, i-geography isungule umehluko phakathi kwawo. I-gulf, i-bay, ne-inlet, noma ngabe ine-morphologies efanayo, yabelana ngomehluko ngobukhulu nokujula. Ngalesi sizathu, igebe lingelokuqala elinosayizi nokujula okukhulu kakhulu, lilandelwa amatheku, lincane kancane futhi lingajulile futhi liphela ngokungena.

Izindawo zokungena zishiyelwe indawo yokugcina, kusukela emncane kakhulu futhi engajulile kangakoEsikhundleni sokuguqulwa ngogu, balungiswa ngamatshe aphumela olwandle kusuka olwandle.

Okuhlangene ngokufana kwala ma-geomorphologies amathathu ukuthi kuhloselwe ukwakhiwa kwamachweba ukuthuthukisa umnotho wendawo. Amachweba angakhiwa kalula, njengoba amanzi ebuthakathaka futhi lezi zakhiwo zivikela ekukhuphukeni kwamagagasi.

Ngaphezu kwalokho, ubuhle ababuhlinzekayo ngamasimu, amaphuzu abalulekile emnothweni womhlaba, Hhayi nje kuphela ngenxa yokwakhiwa kwamachweba, kepha futhi kuhloswe ukuba kube yizindawo lapho kuthengiswa khona izimpahla ngezinga elikhulu, zombili lezo ezifika zivela ezweni elithile, kanye nalokho okushiya, kuvame ukufunwa izindawo zokuvakasha, njll.

Izindawo zokungena, ezincane ngosayizi nokujula, azisetshenziswa kakhulu ekwakhiweni kwamachweba, yize kwesinye isikhathi kwakhiwa amadoko amancane, zisetshenziselwa ukusetshenziswa njengamabhishi, sibonga iqiniso lokuthi amatshe ayawavala amanzi futhi awawavumeli ukuba abe namagagasi noma imisinga enamandla.

Amagebe aziwa kakhulu emhlabeni

Lapho usuyifundile incazelo yeglovu nokwehluka ngamatheku nangezindawo zokungena, sekuyisikhathi sokwazi amagebe abaluleke kakhulu futhi awaziwayo emhlabeni. Kunezikhala eziningi emhlabeni, kepha ezibaluleke kakhulu ngezinga elikhulu yiGulf of Mexico, iGulf of Alaska neGulf of St. Lawrence.

IGulf of mexico

IGulf of Mexico itholakala phakathi kwamaphethelo aseMexico (ezifundazweni zaseTamaulipas, eVeracruz, eTabasco, eCampeche naseYucatán), izingqimba zase-United States (ezifundazweni zaseFlorida, Alabama, Mississippi, eLouisiana naseTexas) kanye nogwini kusuka esiqhingini saseCuba (engxenyeni esempumalanga ye-gulf, ethekwini layo kuya e-Atlantic Ocean).

IGulf of alaska

IGulf of Alaska ihlanganisa umkhawulo ogobile woLwandlekazi iPacific ogwini oluseningizimu ye-Alaska, luboshwe ngasentshonalanga yiNhlonhlo yase-Alaska nesiQhingi sase-Kodiak, nasempumalanga yi-Alexander Archipelago eGlacier Bay. IGulf of Alaska likhulu kakhulu ngokujula nangobubanzi obuthathwa njengolwandle.

Ubuningi bemvula eqoqwayo ngezikhathi zezimvula ePacific Northwest kwenzeka kuleli gebe. Ugu lunolaka kakhulu futhi luneminyango ejulile. Kubo bonke abangaya ukuyobona, ungakujabulela ukubukeka kwamahlathi, izintaba kanye nezinguzunga zeqhwa ezisuka ogwini.

Umfudlana omkhulu odabula leli gebe yilowo wase-Alaska. Ungumfudlana oyingxenye yebhande lokuhambisa, ufudumele ngesimilo futhi ugeleza uye enyakatho.

Ngenxa yezimo zayo zokwakheka nokwakheka kwayo, iGulf of Alaska idala izivunguvungu ngokuqhubekayo. Lo mkhuba wanda ngokuvama nangamandla ezindaweni ze-Arctic Circle, lapho izivunguvungu ziqhutshwa yiqhwa eliningi neqhwa. Eziningi zalezi ziphepho ziya ngaseningizimu noma ngasogwini lwaseBritish Columbia, eWashington nase-Oregon.

IGulf of Saint Lawrence

Leli gebe lisempumalanga yeCanada futhi lixhuma ne-Atlantic Ocean. Igebe elibanzi impela. UMfula iSt. Lawrence uqala eChibini i-Ontario futhi, ngokusebenzisa ichweba elikhulu kunawo wonke emhlabeni, uthululela kuleli gebe.

Ngalolu lwazi uzokwazi ukwazi kahle umehluko phakathi kwamagebe, ithebe kanye nokungena futhi wazi amagebe abaluleke kakhulu emhlabeni.
