Olwandle encane kunazo zonke emhlabeni: indawo, usayizi,

Uyini ocean encane kunazo zonke emhlabeni? Impendulo yalo mbuzo ungayithola ezitholakala kulesi sihloko. Ngaphezu kwalokho, bheka ukutshelwa ukuphi, yini endaweni yakhe, ohlala kuwo, amanye amaqiniso athakazelisayo ephathelene nayo.

izilwandle

Izingxenye ezimbili kwezintathu ebusweni iplanethi yethu ithatha indawo amanzi. endaweni kwayo ngokuphelele kuyinto abantu abangaba yizigidi ezingu-370 km ^2. Namuhla umphakathi womhlaba ikhomba izilwandle ezinhlanu zomhlaba:

1. uthule;
2. Indian;
3. eNingizimu;
4. Atlantic;
5. Arctic.

Lokhu kuhlukaniswa wamukelwa International lokuhlola amanzi Inhlangano ngo-2000, lapho izilwandle zomhlaba lahlukaniswa ngokusemthethweni kulezi ezinhlanu.

Umugqa ohlukanisa engumzimba owodwa omkhulu wamanzi kusuka kwenye okunemibandela. Amanzi angabamba ageleze ngokukhululeka komunye ocean kwenye. On kwemingcele yabo kuba khona kungahambisani sezulu, ikakhulukazi imisinga kanye nezinye izenzakalo.

Ake sibone ukuthi yini ulwandle encane kunazo zonke emhlabeni kuka kuyathakazelisa ngubani ezikuyo. Izimpendulo zale mibuzo enzima unika isayensi Oceanography.

Arctic

Olwandle encane kunazo zonke emhlabeni - Arctic. A ungqimba obukhulu Arctic ice unyaka wonke ihlanganisa ingxenye enkulu endaweni yayo.

Ngokokuqala ngqá German Ocean uvele kumephu ekhulwini lesikhombisa. Ekuqaleni lalibizwa Hyperborean. Ngokuvamile, umlando khona kwaso, kwadingeka amagama amaningi kakhulu, eziningi zazo zibonakala indawo yayo ezindawo.

Igama lanamuhla elithi olwandle zase zihleliwe ekuqaleni yekhulu nesishiyagalolunye, emva wamazwe ucwaningo Admiral F. P. Litke.

Kuyinto enomoya kuzo zonke izilwandle kusezweni akhelene amanzi zasePacific Atlantic. Ukujula kuhluka 350 m 5527 km, naphakathi - amamitha angaphezu kuka-1200, inani lamanzi - ³ 18 million amakhilomitha. Amanzi multilayer ocean: lokushisa ezahlukene kanye usawoti degree. Ngokuvamile mirages, okuyinto akhiwa ngenxa ukushayisana afudumele futhi abandayo emoyeni uquqaba.

Le ndawo wamanzi e-Arctic Ocean kuhlanganisa ezilwandle nambili. Isenzakalo esidume kunazo zonke kubo: White, amaChukchi Sea, Laptev Sea, oLwandle uBarents, nabanye.

isikhundla ezindawo

Arctic Ocean - ulwandle encane kunazo zonke emhlabeni. Igama ebizwa ngokuthi isikhundla salo ezindawo. Le ndawo ihlanganisa North Pole, kanye iningi Arctic and bands sub wonke. Ezingwini bahlanza yi amazwekazi amabili elikhulu amanzi alo.

okushisa aphansi kakhulu, lapho ukubusa emimoyeni ebandayo arctic ka, eside nobusuku obungamashumi elimboze izindawo ezibandayo kanye, ngenxa yalokho, ukuntuleka ukushisa kwelanga kanye nokukhanya, nemvula encane kakhulu - konke lokhu kwenza isimo sezulu ezinzima kakhulu. Ngaphezu kwalokho, lena ocean encane kunazo zonke emhlabeni ngenxa yokuntuleka ukushisa esikhathini esiningi embozwe slabs yeqhwa emikhulu.

Lezi zingqimba ziyahamba njalo, njalo njalo inqwaba yeqhwa emikhulu kwakhiwa.

Ubukhulu

Arctic Ocean - ulwandle encane kunazo zonke emhlabeni by endaweni. It ebangela 3.5% ukunikezela emhlabeni yamanzi. Ngokuvamile, kungcono cishe ezingu-15 km ^2. Uma siqhathanisa nge elwandle eliKhulu iPacific, iyona enkulu kunazo zonke emhlabeni, i-Arctic - kungcono nje okweshumi kwakhe.

Cishe isigamu endaweni elalihlala emashalofini ezwekazini. Ukujula lapha incane, cishe ngo-350 metres.

Esikhathini Ingcenye ephakathi kukhona eziningana emigodini ejulile kuze kufinyelele 5000 amamitha. Basuke bahlukana emikhulu transoceanic (Haeckel Mendeleva, University).

izakhamuzi

Iningi Arctic Ocean kakhulu onyakeni embozwe iqhwa, ngakho musa zidonse ukunaka kwanoma amatilosi nabadobi. A kancane lapha zezinto eziphila emanzini kanye nezitshalo. Nakuba namanje kukhona abamele abalandeli nesimo sezulu esibandayo.

Lapho amanzi kukhona ucishe khulula ice, kukhona izimvu zamanzi, walruses, amabhere, imikhomo, izinhlanzi ezincane ne-shellfish.

Izilwane Arctic Ocean, njengoba, empeleni, kubo bonke ezindaweni ezisenyakatho, libhekene ezinye izici ezikhethekile. Omunye wabo - gigantism. Lokhu kufakazelwa ukuba khona kwengqalabutho izimbaza ezinkulu futhi jellyfish, amakhorali, ulwandle izicabucabu.

Esinye isici - kungcono kade. imfihlo yakhe ukuthi zonke izinqubo zokuphila ehlile at okushisa aphansi.

Izimbaza baphile lapha engamashumi amabili nanhlanu, futhi oLwandle Olumnyama - eziyisithupha kuphela; cod elisekhona eminyakeni engamashumi amabili, futhi i-halibut ngokuvamile kuze kube iminyaka engamashumi amathathu noma engamashumi amane.

amaqiniso ezithakazelisayo

1. Olwandle encane kunazo zonke emhlabeni endaweni yesibili ngemva Pacific ngenani iziqhingi zitholakala insimu yalo.
2. Amanzi endaweni has in ukubunjwa yayo yisona siqhingi esikhulu kunazo zonke emhlabeni (Greenland) futhi lezi ziqhingi ngobukhulu (Canadian Arctic).
3. Iningi olwandle amanga phansi iqhwa unyaka wonke.
4. Phakathi kwalezi ziboshwa kwatholakala jellyfish saba enkulu. Lalibizwa ngokuthi Cyanogen, kumayelana ezimbili amamitha ububanzi futhi ihambe kuze kube ngamamitha amabili.
5. Futhi uhlala lapha ulwandle spider inesipani umlenze kuze kube amathathu ngamasentimitha.
6. On the amabhange olwandle elincane isilwane engavamile - must inkabi.
7. Ngenxa endaweni sifudumale futhi ice ukujiya ziyancipha kakhulu. Kutfutfukisa ibe inkinga ezinkulu emvelweni: amanzi zamaqhwa zincibilika ukuwela izilwandle ezingeni layo uzovuka. Uma sicabanga ukuthi zonke zamaqhwa iyogcwala amanzi, ezingeni bayovuka ngamamitha ayisithupha.
8. Abavakashi bathini mayelana umsindo lomkhuba ocean abahlebayo imisindo eziningi amakhilomitha.
9. Lo mkhuba Fata Morgana, kwakhiwa okuyinto kusukela mirages ngokulandelana sici Arctic, hhayi nje abahambi ukudideka astray. Lesi simo esiyingqayizivele sibangelwa okushintsha kakhulu isimo sezwe, okubonisa yangempela ifomu uhlanekezelwe kakhulu.
