Pacific

Qala sibala elwandle nokuwahlamba Umzantsi Melika umi kwiPasifiki. Nguye lo mdala nomkhulu ehlabathini, kunye ummandla million 178 leekhilomitha. lula indawo enjalo nakho ukwamkela onke amazwekazi ngexesha elifanayo. Igama edibene umhambi uFernand Magellan, ngubani kuqala watyelela ulwandle kwimozulu entle yaye uyotywe yi ukuchulumacha yayo. Yena lesishwankathelo elimbhoxo kunye ebanzi kakhulu kwi-ikhweyitha. A ngenene liphela bangaphanda kuphela kwinkulungwane yeshumi elinesithoba, nangona kwiphulo lokuqala ukuhlola unxweme Umzantsi Melika Line iye yenziwa yi uJames Cook kunye uFernand Magellan. Ngoku le miba kusingathwa ngumbutho ekhethekileyo ngamazwe.

Iziqithi eTuamotu ocean idla uvuthuzayo, kodwa kufuphi nonxweme Umzantsi Melika, imozulu ukumelana, umoya ukukhanya. Baninzi ezizolileyo luphawulwa iishawa ngamaxesha. Pacific ukusebenza olubonakalayo ngokuphila kumazwe yoMzantsi Merika. States abaninzi benza lokuloba emanzini, squid atsalwa, oononkala ulele ezityiwayo bazibonise kwiingingqi ezithile.

ulwandle Atlantic

Zibala ulwandle nokuwahlamba Umzantsi Melika, okwesibini sikhankanye i-Atlantic. Lufikelela kuyo kommandla million 92 ezikwere zeekhilomitha kwaye azakubalulwa into olumanyanisa iingingqi polar behlabathi. Ocean Centre wabamba Mid-Atlantic Ridge, anokuthi amanzi kuvuka ezahlukeneyo iziqithi mlilo. Eyona idumileyo lwabo Iceland. Kufuphi nonxweme Umzantsi Melika, lo ngowona inxalenye zinzulu: Puerto Rico Trench ufikelela onobunzulu kweemitha 8742. Xa igalelo yimvula imimoya zorhwebo kumzantsi-lasempuma yaye akukho iinkanyamba, elunxwemeni of Brazil abe umbala oluhlaza, lo gama iinkalo ezishiyekileyo longanyelwe obhulowu bumnyama.

E Umzantsi Melika, phawula isiphumo sale wolwandle yezinto ezinzima.

ulwandle Caribbean

Indawo yezwe kuchaphazela ngamandla ubomi kubahlali bayo, ushishino kunye imozulu. Ukufunda kwezilwandle nokuwahlamba Umzantsi Melika, oku kulula ukubona. Umzekelo, noLwandle lweCaribbean - ummandla ethandwayo neeholide yokuhamba kule ndawo, osisityebi ioli. Le ise kumantla Umzantsi Melika, ahlanganise indawo kweekhilomitha million 2 square. It ohlamba kunxweme eVenezuela, Colombia, Panama, Costa Rica, eNicaragua, Honduras, Guatemala, Belize, weYucatán, Cuba, esiti, Jamaica kunye Puerto Rico. Kukho izixhobo ezininzi izixhobo.

nemisinga efudumeleyo

Uhide yolwandle nokuwahlamba Umzantsi Melika, abantu abaninzi silibale malunga imisinga. Okwangoku, oko kubizwa ngokuba impazamo enzulu, ngenxa yokuba kaninzi ukukhangela imozulu kunxweme. Le ndawo ishushu Umzantsi Melika ekunokuthiwa iinxalenye Atlantic, i-Ocean Pacific ufudumele. ugu ingakumbi wabalaselisa akramnceleyo yi-Guiana neentsingiselo eBrazil, ukuba zezona ukhululekile kwaye yenza inxalenye nempuma yeli lizwekazi njengendawo ngokuya ithandwa sokhenketho.

flow ebandayo

Kweelwandle neelwandlekazi nokuwahlamba Umzantsi Melika, efudumeleyo ngokwaneleyo, kodwa umahluko amanzi obonakalayo kakhulu. In the Pacific kude ngakumbi ebandayo imilambo, uninzi lwazo basondele nezwe. Umzekelo, kufuphi Antarctica Umzantsi Melika kokuhlanjwa Falkland yangoku kunye West Wind Drift.
