Atlantic Ocean: indawo, umlando, zamanje

Atlantic Ocean, isikhundla ezindawo zazo kuchaziwe ngezansi, - ingxenye izilwandle zomhlaba. Lena enye yezinhlobo ezingu amadamu 4 ezinkulu emhlabeni. Ubukhulu sesibili ngobukhulu, ngemva Pacific. Ebusweni endaweni - abayizigidi ezingu-92 amakhilomitha square, lokulandisa 25% wabo bonke amanzi kule planethi .. Empumalanga, umkhawulo ocean Eurasia nase-Afrika, kusukela North - aseNingizimu naseNyakatho Melika, endaweni eseningizimu-Atlantic uthola e-Antarctica. Isilinganiso olwandle ukujula - 3 500 km, kanye esiphezulu - 8742 m (sikhuluma mayelana Puerto Rico Trench).

Atlantic Ocean - isikhundla ezindawo

endaweni Water osuka kule enyakatho nesifunda eningizimu Zomhlaba, ukweqa sub-Arctic nase-Antarctic zindawo. Amaphuzu kakhulu nolwandle ngokwanele ebanzi futhi ijulile, kuyilapho ukufinyelela yenkabazwe, ubude bayo kuyehla kube 2 900 km. Cape Agulhas liwumngcele ophakathi kwe-Atlantic izilwandle Indian, futhi eCape Horn sihlukanisa indawo echazwe futhi ePacific Ocean.

Umsuka kwegama ocean imfundo

Incazelo Atlantic kufanele kuqale lapho ivela khona. Yasungulwa ngenxa uqhekeko yasendulo izwekazi Pangea, sivela ezingxenyeni chipped okuyinto wazithatha amazwekazi yesimanje. Igama olwandle uvame elihlobene ne-Atlantis - isiqhingi wasenganekwaneni lasendulo ukuthi ezinkulungwaneni zeminyaka edlule waya ngaphansi emanzini, mhlawumbe olwandle. Enye samuntu sifana igama Atlas ezintabeni (Africa).

ocean phansi

ugu Atlantic kuwumsebenzi sihlehliswe kakhulu, futhi inani eliphelele thutheleka fula olwandle noma ulwandle, okungaphezu kwalokho ezinye izidumbu omkhulu wamanzi. Lesi sici, okuyinto iyahlule nezinye ulwandle. phansi abahlukile, okuyinto izici eziyinkimbinkimbi kakhulu morphological esivela amanzi ezifana Atlantic Ocean. Indawo Geographical uchaza kalula leli qiniso. Ngaphesheya obuphelele ocean 16 000 km, ke welula Atlanticheky Mid-Range. Lena indawo ukugadlwa ukuzamazama komhlaba asebenzayo nge engazinzile emhlabeni uqweqwe. Ngezinye izikhathi yokhalo izintaba-mlilo ngaphansi kwamanzi eze kwamanzi. Isibonelo izakhiwo ezinjalo iyisiqhingi ye-Iceland. Kuvamile ukuba phansi - .. Basin, ukujula avareji imayelana ayizinkulungwane 5-7 amamitha kakhulu ngokujulile leli fomu wokukhululeka - North American, ukuphakama kwayo kuyinto 8742 m Nokho, ukukhulisa, emikhulu namagquma -. Ingabe futhi evamile Atlantic Ocean. Phansi embozwe daka, ikakhulukazi foraminiferal. Eduzane amazwekazi ebusweni ezinodaka usuthathelwa ezifakwa terrigenous: amatshe, amatshe nesihlabathi. Emigodini ejulile ngezansi ikhombisa ubumba abomvu.

Isimo sezulu

Kunezinhlobo ezihlukahlukene izimo zezulu olwandle kubangela ke osuka eningizimu kuya empumalanga. It idlulisela zonke sezulu esihlukahlukene - amakhaza hot Antarctic enkabazwe. Atlantic lokushisa olwandle ikufanele elinamandla kusukela North bamanzi Arctic. Ngasogwini eNyakatho neMelika, budebuduze Florida, ozalwa wamanje ngobukhulu efudumele - Gulf Stream. ububanzi - 75 km, i-ka-ukugeleza ukujula -. 700 m Gulf Stream ithwala amanzi afudumele, nezinga lokushisa - 26 degrees ngenhla zero.

imisinga

Kuye ngendawo, ekushintsheni ukugeleza rate. Ezindaweni ezimaphakathi nolwandle kuba 6 m / s. Maximum ukugeleza rate - 30 m / s. Enyakatho-mpumalanga Gulf Stream ingena eNyakatho ye-Atlantic yamanje, okuyinto yena, ihlukaniswe ukusakaza ezimbili. Omunye ifinyelela umkhawulo wakwa-Norway, okubangela lezi zindawo efudumele, engavamile kule ndawo, isimo sezulu kanye Neyesibili - "eMpumalanga" futhi ubelokhu eqashelwa ngoba amakhaza yamanje eCanary Afrika engeSewula. Eningizimu, ke agelezela North Equatorial, kanti isixuku esikhulu, esikhundleni salokho, eyakhelene Gulf Stream. Bonke bayingxenye Atlantic Ocean umcengezi. Ngakho, kuvela ukuthi ngokuhamba amanzi echazwe lihamba ngendlela isiqondiso ngokwewashi, amakhaza usuthathelwa kulungele, noHezekeli.

Kanye-Atlantic ugu lweNyakatho Melika labetibambile amakhaza Labrador yamanje, okubangela enokhahlo futhi abandayo sezulu Canada kanye Greenland. Endaweni lapho okuhlatshelwa khona-ke ishayisa Gulf Stream, yakheke "umgqomo Newfoundland" e sifinyelela ongenhla lapho kuyinto enhle zizalela emhlabathini kwezilwanyana ezincane. Godu bathuthukisa yokudoba isikhathi yezimayini i-herring, ama-salmon nama-cod.

iziqhingi

It akanawo inombolo enkulu iziqhingi amanzi ezifana Atlantic Ocean. Isikhundla womhlaba, futhi, yachaza konke. Zakhiwa ngokuyinhloko single futhi ezahlukene endaweni encane. Okuwukuphela Greenland, esemgwaqweni emngceleni ophakathi kwe-Atlantic North-Arctic Ocean kanye Iceland. Elikhulu isiqhingi Atlantic - obakhathalelayo. Saint Helena, oh. Sao Paulo, obakhathalelayo. Bouvet obakhathalelayo. . Ascension, zaseFalkland kanti elinye inamandla into lalivamile engxenyeni eseningizimu olwandle - eziqhingini, kodwa akaphumelelanga (indawo coral).

I zezilwane nezimila

Nezilwane imelelwa abampofu zinhlobo Ukwakheka, ikakhulukazi emaphethelweni echibini. Pool Atlantic Ocean 'zingaziqhayisa "inani elikhulu Pike elimhlophe-ngesihluku. ezincelisayo ezinkulu emanzini kuhlale imikhomo, izimvu zamanzi kanye zamanzi ezinoboya. Flora imelelwa ezihlukahlukene enkulu zasolwandle - Sargassum. Baze bakha Sea Sargasso ngasogwini lweNyakatho Melika, uhlaka yayo kungenziwa ewubona esemkhathini.
