Atlantic Ocean: malo enieni mbiri, ndi panopa

Atlantic Ocean, malo Hrs chimene pansipa, - chigawo chimodzi cha nyanja dziko. Ichi ndi chimodzi mwa malo 4 lalikulu la dziko. Ukulu ndi wachiwiri kukula, pambuyo Pacific. M'dera padziko - makilomita lalikulu miliyoni 92, mlandu 25% zonse madzi lathuli .. Kum'mawa, malire nyanja Europe ndi ku Asia ndi Africa, ku North - South ndi North America, ku dera kum'mwera kwa Atlantic amapatsidwa Antarctica. Wapakati akuya nyanja - 3 500 Km, ndi pazipita - 8742 mamita (tikulankhula za Puerto Rico ngalande).

Atlantic Ocean - malo Hrs

m'dera madzi umachokera ku kumpoto kwa dera kum'mwera kwa Dziko kufika boma Arctic ndi M'madera a zitunda Antarctic. Mfundo kwambiri pa nyanja ndi mokwanira chachitali komanso chozama, pamene kufika equator, m'litali yafupika 2 900 Km. Cape Agulhas ndi malire pakati pa Atlantic ndi nyanja ya Indian ndi Cape Horn ukugawa gawo anafotokoza ndi Pacific Ocean.

Chiyambi cha maphunziro dzina ndi nyanja

Kufotokozera za Atlantic ayenera kuyamba pakuwonekera kwake. Inakhalapo chifukwa cha kugawanika kwa wakale kontinenti a Pangea, kuchokera kumadera imawazidwa amene anayambika m'maiko ano. Dzina la nyanja nthawi zambiri amagwirizana ndi Atlantis - lakale lanthano chilumba zaka zikwizikwi zapitazo anapita pansi pa madzi, mwina nyanja. chimake wina akufanana dzina la Atlas mapiri (Africa).

pansi pa madzi

Atlantic m'mphepete mwa nyanja ndi indented kwambiri, ndipo chiwerengero cha mitsinje m'nyanja kapena nyanja, kuposa wa matupi zina zazikulu za madzi. Mbali imeneyi, yomwe chimasiyanitsa izo kwa nyanja zina. Wapadera pansi, zomwe ndi zovuta zinthu morphological chibadidwe madzi monga Atlantic Ocean. malo Geographical mosavuta anafotokoza mfundo imeneyi. Kudutsa kutalika nyanja ya 16 000 Km, izo akutambasula Atlanticheky Mid-osiyanasiyana. Izi ndi malo seismically yogwira ndi wosakhazikika lapansi kutumphuka. Nthawi zina lokwera m'madzi mapiri kubwera pamwamba. Chitsanzo cha nyumba ngati chilumba cha Iceland. Sizachilendo kuona pansi - .. beseni kuya avareji zikwi 5-7 mamita kwambiri ndi mawonekedwe mpumulo - North America, kutalika kwake ndi 8742 m, Komabe, kwezani, zitunda ndi mapiri -. Kodi inunso si zachilendo kuti Atlantic Ocean. pansi ali ndi matope, makamaka foraminiferal. Pafupi ndi m'maiko matope pamwamba agonjera ku madipoziti terrigenous: timiyala, miyala ndi mchenga. Mu m'maenje kuya kwa pansi limasonyeza dongo wofiira.

nyengo

A zosiyanasiyana nyengo ya nyanja amachititsa kuti umachokera ku kum'mwera kum'mawa. Iwo analanda mabacteria onse nyengo - kuchokera ozizira otentha a kunyanja ya Antarctic. Atlantic kutentha nyanja labwino ndi mphamvu ku North wa madzi Arctic. Gombe la North America, Suli kutali Florida, wobadwa yaikulu ofunda apano - Gulf Stream. m'lifupi - 75 Km, kuya kwa otaya -. 700 mamita Gulf Stream amanyamula madzi ofunda, pafupifupi kutentha - 26 madigiri pamwamba ziro.

mafunde

Malinga gawo, kusintha mlingo otaya. Mu zigawo chapakati pa nyanja ndi 6 m / s. mlingo pazipita otaya - 30 m / s. Mu kumpoto cha kum'mawa kwa Gulf Stream akulowa North Atlantic Current, amene nawonso, lagawidwa mitundu iwiri. Mmodzi umalandira gombe la Norway, kuchititsa malo awa ofunda, zachilendo am'derali, nyengo ndi kachiwiri - "n'kugwa" ndipo umachitika kwa ozizira Canary Current pa Kumwera Africa. Kum'mwera, wasefukira mu North Equatorial ndi yamasika, nayenso ali pafupi ndi Gulf Stream. Onsewo ali mbali ya Atlantic Ocean beseni. Choncho, likukhalira kuti m'kupita kwa madzi zinalongosoledwa akusuntha mu mobwerera malangizo, ozizira agonjera ku konzekera ndi mosemphanitsa.

Pamodzi Atlantic gombe la North America anagwirizira ozizira Labrador Current, kuchititsa wouma mtima ndi ozizira nyengo ya Canada ndi Greenland. Kumalo kumene izo collides ndi Gulf Stream, aumbike "Newfoundland mbiya" mu malire chapamwamba amene ali abwino kuswana pansi tizilombo. Komanso anayamba nsomba kwa hering'i migodi, nsomba ndi nsomba zoterezi za m'nyanja.

zilumba

Zilibe ambiri zilumba madzi monga Atlantic Ocean. Udindo Hrs, kachiwiri, anafotokoza zonse. Iwo zigwirizana makamaka a m'gawo limodzi ndipo zosiyanasiyana zolowa. Yekha ndi Greenland, limene lili kumalire pakati pa Atlantic ndi Ocean North Arctic ndi Iceland. Large Atlantic chilumba - za. Saint Helena, oh. Sao Paulo, za. Bouvet za. . Ascension, ndi Falkland Islands ndipo enawo chodabwitsa zofala kum'mwera kwa nyanja - pa zilumba zimenezi zili (gawo matanthwe).

The zinyama ndi zomera

zomera The ukufanizidwa ndi osauka mitundu zikuchokera, makamaka mzinda wa dziwe. Pool Atlantic Ocean akhoza 'kudzitamanda "ambiri zoyera blooded Pike. Nyama Large m'madzi anthu zinsomba, zisindikizo ndi zisindikizo ubweya. Flora ukufanizidwa ndi lalikulu zosiyanasiyana za Seaweed - Sargassum. Iwo ngakhale zimapanga Sargasso Sea gombe la North America, ndondomeko yake Tingaone danga.
