Olwandle enomoya emhlabeni: sezulu emhlabeni organic

Bambalwa abantu babe nanoma yikuphi ukungabaza ngokuthi okuyinto olwandle enomoya eplanethini yethu. Ngokungangabazeki, lokhu e-Arctic. Itholakala phakathi amazwekazi ezifana eNyakatho neMelika eYurophu nase-Asia, bangazihluphi indawo amakhilomitha square nje kwetigidzi letili-13. Engxenyeni eseningizimu olwandle cishe ngokuphelele kufakwe ngaphakathi kwe-Arctic Circle. Ukujula ovamile we 1225 amamitha, kuyilapho ngobukhulu - 5527 amamitha.

Olwandle enomoya emhlabeni engxenyeni emaphakathi has a eziyize usayizi ezijulile okusaqanda ka 2250 x 1130 amakhilomitha. It is yaziwa nangokuthi Polar noma Arctic umcengezi. Cishe isigamu ekujuleni kolwandle kuyinto eshalofini ngaphakathi inqwaba iziqhingi ngabanye kanye leli qoqo leziqhingi. Lezi zihlanganisa Greenland, eSiberia Islands, eNyakatho kanye Novaya Zemlya, Svalbard and abanye. Kufanele kuqashelwe ukuthi ulwandle enomoya emhlabeni ayinakho iziqhingi Lokudabuka wasolwandle.

Inzika lapha uwela ikakhulukazi ngesimo kweqhwa, kuyilapho imvula ezingavamile kakhulu. Zonke ngonyaka iningi endaweni olwandle imbozwe yiqhwa, okuyinto ukushuba isilinganiso ngamamitha amathathu. Ukuze esifundeni entshonalanga libhekene umoya ezindaweni zayo enyakatho-entshonalanga nasenyakatho, okuyizinto imbangela eyinhloko ezinzima sezulu arctic. Engxenyeni esempumalanga ezizungeze ubuswa imimoya ningizimu-ntshonalanga futhi eningizimu, futhi ke kukhona ulwandle abandayo Isimo sezulu sikahle.

Umoya nendlu yaqala ukufudumala ehlobo akuyona kakhulu. Amazinga isilinganiso ezindaweni ezahlukene e-Arctic Ocean kuhluka amabili kuya nambili ngaphansi kwezingaqhwa degrees Celsius. Ebusika, kungashiwo ivinjelwe lapha ngezansi degrees lokususa amane. Winter iziphepho ngokuvamile zenzeka.

Olwandle enomoya emhlabeni kungaba ukuziqhayisa a flora ocebile ezilwaneni nasezimileni. Isizathu salokhu iyona izimo zezulu elibuhlungu, kanye ice okwandile. I amaningi asethuthukile emhlabeni organic esifundeni lapho kukhona uxhumano okuqhubekayo ukuze Atlantic Ocean, ngamanye amagama - e White, uBarents futhi Kara iziLwandle. Lihlala kungathi izinkulungwane ezimbili zezilwane (phakathi lapho imikhomo), kanye omningi izinhlanzi. Kulezo kwamanzi, awela amanzi ofudumele esiqhingini osogwini olusenyakatho namawa ungathola izinyoni eziningi.

Esikhathini Alaska esifundeni, Canada ne-Eastern eSiberia, izwe organic ayiyinhle kakhulu. Isimo esifanayo abahlala engxenyeni ephakathi ye-Arctic Ocean, embozwe iqhwa unyaka wonke. Lapha phytoplankton umelwe ngokuyinhloko diatoms. Ezinye zazo baphile phezu ice. Kepha zooplankton, ulwandle enomoya emhlabeni kule ngxenye akha zinhlobo esingaphansi ayisishiyagalombili, ubuswa cod nesafroni, cod polar ne-cod phakathi izinhlanzi. On emaphethelweni ice ubudala zingatholakala lwezimpawu ngokuvamile, walruses, imikhomo beluga Narwhal, elezinye izilwane ezincelisayo ulwandle. ukudoba yabo manje nhlobo futhi waqashwa amathuluzi eminingi emhlabeni jikelele. Omele bhá nezilwane ezihamba ezweni nansi polar bear.
