Olwandle kencanikhulu - Arctic

Oceans uhlelo nzima ukuthi kuhlanganisa ezine olwandle. Kuyinto yomhlaba ocebile ophila ukuphila ayo, ezihlukahlukene nezithakazelisayo. Olwandle kulencane - kuba e-Arctic. Itholakala engxenyeni ephakathi ye-Arctic. Cishe kuzo zonke izinhlangothi lizungezwe izwe (i-Nyakatfo Melika eYurophu nase-Asia).

Akukhona nje kuphela komncane kunabo ocean of the Earth, kodwa futhi enomoya. Lokhu kungenxa isikhundla salo ezindawo. Iningi olwandle embozwe iqhwa, ngakho-Arctic Ocean ingxenye yokuzamazama ka izilwandle zomhlaba. It is hhayi ngakho ayenziwa lokuthumela.

Kodwa ulwandle kubaluleke kakhulu e eziyingxenye yesu lobuciko. indawo yayo ikuvumela ukuba uthole enqamulelayo kusuka eNyakatho neMelika eRussia. Ngakho-ke, ngemva kweMpi Yezwe II, waba into balifundisise sinombono zisebenzise izinhlelo wezempi nesayensi.

Olwandle kulencane uye yindawo mikhankaso eminingi icebreakers, ngwenya. Inkantolo wathutha kwaze kwaba phakathi eqhweni, phansi ngaphansi Uhlonze lwalo ukujula. Ucwaningo lwenziwe phezu ukukhukhuleka zeqhwa.

Impumuzo olwandle elincane esigodini ezijulile, okuyinto lizungezwe kwezilwandle. Le ndawo olwandle million 14,75 amakhilomitha. Half eshalofini layo, ukufinyelela ububanzi esiphezulu 1300 amakhilomitha. Kulapha anakho ukujula omkhulu kunayo yonke futhi ugu oluhle ezahlukene sihlehliswe. Njengoba esungulwe, kuba nemiphumela kumiswa yeqhwa.

Lo mgodi emaphakathi ifinyelela ububanzi kufika ku 2250 amakhilomitha. Udabula maphakathi kwamanzi Lomonosov Ridge Intaba. I olwandle kulencane ukujula enkulu ifinyelela ngezithuba 5527 amamitha. Leli phuzu e Sea Greenland.

IBering Strait uxhuma Arctic nePacific futhi ehlukanisa Alaska futhi engxenyeni esenyakatho ye-mpumalanga ye-Asia. Ukwahlukana Umngcele osuka Atlantic Ocean sidlula kolwandle, isihloko Norwegian esemgwaqweni phakathi Greenland naseYurophu.

Isikhundla ezindawo ka the ocean inquma eziningi zezici zalo. Ngokwesibonelo, uthola amandla elanga ngamancozuncozu kunamanye izingxenye izilwandle. Ngakho, izinga lokushisa yayo amanzi ngokwanele ongaphakeme, futhi iningi ocean embozwe iqhwa. Ukwakheka kwazo ngokwama-akuyona iyunifomu. Kwezinye izingxenye ice akheke okuqhubekayo, kanti kwezinye amabhlogo ice kungukuthi soldered ndawonye.

Ikhava ice uyashintsha futhi, kuye ngokuthi yisiphi isikhathi sonyaka. Ngenxa yokuthi lokuthumela endaweni athuthukile ukunyakaza kancane uhlamvu angakafakwa wafunda. Iningi miphumela yayisho wenza ngesisekelo ukutadisha ukunyakaza nemikhumbi, zivaliwe ku amabhlogo ice.

Kwatholakala ukuthi ikakhulukazi amanzi e-Arctic Ocean kuletha zamanje Norwegian. Khona-ke amanzi exhunywe kwi-Pacific Ocean, uyeza ngokusebenzisa iBering Strait.

Izilwane nezitshalo zezwe olwandle akuyona ezahlukene kwezinhlobo ukujula. Lokhu kungenxa indawo yayo ezindawo kanye izimo zezulu. Ice akavumeli kwelanga okwanele, okuyinto evimbela izitshalo ukuthuthukisa ngokugcwele. Eduzane Eurasia ahlangane imikhomo, amabhere, izimvu zamanzi namanye izilwane.

Ukukhuluma ngendlela olwandle luncane, kufanele kuphawulwe ukuthi e-Arctic Ocean kubaluleke kakhulu esintwini, futhi ucwaningo lwakhe abathintekayo emazweni amaningi.
