Atlantic Ocean: indawo, imbali, yaye ngoku

Atlantic Ocean, indawo geographical ngayo ichazwa ngezantsi, - icandelo kwiilwandle zehlabathi. Le yenye amadama ezinkulu 4 planethi. Yobukhulu ke yesibini ngobukhulu, emva wePasifiki. Le kobuso - million 92 ezikwere zeekhilomitha, olubalelwa-25% awo onke amanzi umhlaba ukuze ujikeleze kakuhle .. Ukuya empumalanga, i umda ulwandle Eurasia kunye Afrika, ukusuka North - kuMzantsi nakuMntla Melika, kummandla ngasezantsi Atlantic ufumana ku Antarctica. I-avareji ubunzulu bolwandle - 3 500 km, kwaye ubuninzi - 8742 m (sithetha i Puerto Rico Trench).

Atlantic Ocean - indawo okuyo

indawo Amanzi asuka ukusuka emantla ukuya kummandla esemazantsi Umhlaba, abanqumla sub-Arctic kunye ezinezinga Antarctic. Amanqaku egqithiseleyo olwandle ubanzi ngokwaneleyo yaye zinzulu, xa kufikelela-ikhweyitha, ubude balo liye lancitshiswa km-2 900. Cape Agulhas lowo umda phakathi Atlantic kunye neelwandle Indian, kunye neCape Horn iyahlula mmandla ochazwe kunye Pacific Ocean.

Imvelaphi yegama nolwandle imfundo

Inkcazelo Atlantic kufuneka uqale ivela khona. Kuye kwasekwa ngenxa ekwahlulweni yamandulo ilizwekazi Pangea, ukusuka kwiindawo chipped eziye zavela amazwekazi mihla. Igama olwandle amaninzi unxulunyaniswa Atlantis - isiqithi yamandulo wasentsomini ukuba kumawaka eminyaka eyadlulayo waya phantsi kwamanzi, mhlawumbe olwandle. Enye ngobuwena kufana igama iintaba Atlas (Africa).

kolwandle

unxweme Atlantic lungqamane kakhulu, kwaye inani elipheleleyo emifuleni elwandle okanye elwandle, ngaphezulu kunoko amanye amaqumrhu omkhulu wamanzi. Lo msebenzi, nto leyo izahlule kwezinye olwandle. ezantsi Unique, apho imiba entsonkothileyo kakhulu morphological ezendeleyo manzi ezifana Atlantic Ocean. Indawo Geographical ngokulula ucacisa le nto. Ngaphesheya ubude ulwandle-16 000 km, oko wolula Atlanticheky Mid-Range. Le ndawo seismically asebenzayo kunye nomhlaba uqweqwe ezingazinzanga. Ngamanye amaxesha ephakeme mlilo kwamanzi ukuza kumphezulu. Umzekelo izakhiwo ezinjalo kwisiqithi Iceland. Eqhelekileyo ukuba emazantsi - .. Basin, ubunzulu umlinganiselo malunga 5-7 amawaka neemitha abaninzi kakhulu olu hlobo isiqabu - North America, ukuphakama kwayo 8742 m, Noko ke, ukukhulisa, nasentshonalanga kunye neenduli -. Ngaba kwakhona ingaqhelekanga ukuba Atlantic Ocean. Emazantsi igutyungelwe udaka, ikakhulu foraminiferal. Kufuphi kumazwekazi kumphezulu anodaka unika indlela bekelelo terrigenous: iingqalutye, igrabile nesanti. Emigodini nasekudeni emazantsi ubonisa udongwe ebomvu.

sezulu

Iintlobo ngeentlobo iimeko zemozulu yolwandle kubangela ukuba asuka ukusuka ezantsi ukuya empuma. It idlulisela yonke imimandla zemozulu - ukusuka abandayo sentshinyela Antarctic shushu. kwamaqondo Atlantic ikufanele elinamandla evela North wamanzi Arctic. Kufuphi nonxweme North America, musa ukuba kude Florida, wazalwa yangoku inkulu efudumeleyo - Gulf Stream. ububanzi balo - 75 km, ubunzulu kwemali -. 700 m Gulf Stream uthwala amanzi ashushu, kobushushu - 26 degrees ngentla zero.

imisinga

Kuxhomekeka intsimi, ukutshintsha isantya sokuqukuqela. Kwimimandla engundoqo yolwandle ibe yi-6 m / s. bomyinge wamanzi - 30 m / s. Kumntla-mpuma we-Gulf Stream kuya North Atlantic Current, mvisiswano leyo, kwelinye icala, yahlulwe yimisinga ezimbini. Omnye ifikelela kunxweme eNorway, ebangela ezi eshushu, engaqhelekanga kule ndawo, imozulu kunye yesibini omnye - "kuwa" kwaye sele kuqhutyelwa ukuba ngoku ebandayo Canary kumZantsi Afrika. Emzantsi, ayajika kungena North Equatorial nevuthisayo, ke, kukuba ezikufutshane ukusa kwiPersian Stream. Bonke bephela ziyinxalenye Atlantic Ocean isitya. Ngoko, kwenzeka ukuba ekuhambeni kwamanzi ezichazwe lihamba ngendlela kwicala langasekunene, ingqele unika indlela ukufudumeza vice versa.

Kunye Atlantic kunxweme Intshona Melika wabamba Labrador ngoku kuyabanda, ebangela ngqwabalala yaye kubanda imozulu of Canada kunye Greenland. Kule ndawo apho engozini Gulf Stream, ezikhandelwa "umphanda Newfoundland" kwi efikelela kuyo nto leyo izimfimfithi efanelekileyo ezincane. Kwakhona Kwathi lokuloba ukuze herring lezemigodi, nesalmon kunye cod.

iziqithi

It ayinayo inani elikhulu kwiziqithi manzi ezifana Atlantic Ocean. I indawo okuyo, kwakhona, uchaza yonke into. Ziqulethe ngokuyintloko zommandla encinane abangatshatanga kunye ezahlukeneyo. Le ngaphandle kuphela eGreenland, nto leyo ukwakweli umda phakathi Atlantic kunye North Arctic Ocean kunye Iceland. Large siqithi Atlantic - ngayo. Saint Helena, oh. Sao Paulo, malunga. Bouvet ngayo. . Ascension, Falkland Islands kunye omnye zesiganeko eliqhelekileyo emazantsi olwandle - coral (intsimi izixhobo).

Izilwanyana nezityalo

Le zezilwanyana bubonakaliswe ukwakheka iintlobo ihlwempu, ingakumbi kummandla ongaphandle ichibi. Pool Atlantic Ocean unako 'ukuqhayisa "inani elikhulu Pike emhlophe zinegazi elibandayo. ezincancisayo ezinkulu emanzini umiwe iminenga, zamanzi yezimvu. Flora imelwe ezahlukeneyo enkulu yohlaza - Sargassum. Bade kwenza uLwandle Sargasso kufuphi nonxweme North America, ulwandlalo yayo kunokubonwa evela emajukujukwini.
