Ma og tahay halka ay ulaha magnetic dhulka

Ma ogtahay in dhulka uu leeyahay 4 ulaha: laba juqraafi iyo laba magnetic? Oo ulaha juqraafi ma beego magnetic ah. Ma rabtaa in aad ogaato meesha magnetic ah Ulaha dhulka? Dhammaadkii qarnigii labaatanaad, sida magacyadooda ay kala yihiin: North - in waxyaalaha moolka dheer oo xeebta waqooyi ee Kanada, iyo xagga koonfureed - qiyaastii boqol kiiloomitir u jirta cidhifka Jacaylku.

Oo halkaas waa inay ulaha lagu magnetic dhulka hadda? waxay si joogto ah u dhaqaaqin. Tusaale ahaan, xagga woqooyi ee 1831 (waqtiga la furay), wuxuu ahaa at 70 degrees. w. ee Kanada. 70 sano sahamisa oo kala horjeeda ka dib markii R. Amundsen isaga hore u at 50 km woqooyi ku helay. Seynisyahanno ku mashquulsan yihiin in this, oo waxay bilaabeen in ay daawadaan. Waxaa soo baxay pole "safri" la sii kordhaya xawaaraha. ay xawaaraha Bilowgii waxaa jiray yar, laakiin kordhay ilaa 40 km / sannad sannadihii la soo dhaafay. At heerka this, 2050, baallaha woqooyi magnetic "diiwaan" ee Russia. Oo maayo kaliya sawiro qurux badan oo ka mid ah nalalka waqooyiga, kuwaas oo loo arki doono ku dhawaad oo dhan Siberia, laakiin sidoo kale dhibaatooyin isticmaalka wareegsan. gaadhista sidoo kale kordhin bannaan iyo rays, t. Si aad. pole The dhow field magnetic Earth ee waa uga yar yahay ee dhulbaraha. cabir ayaa muujisay in 150 sano duurka ku magnetic of Earth ahaa in ka yar 10%. Oo waa hab aad wax ku ool ah ilaalinta ka dhan adag ku nool iyo dibadda shucaaca qoraxda. cir Maraykanka u duulay Dayaxa, waxay ka soo baxday cover oo duurka magnetic of Earth iyo helay nooc sahlan ee bukaanka shucaaca. Oo xataa sida iyagu ma ay arki dayaxa, laakiin si ay u arki karaan meelaha ulaha magnetic Dhulka, kari waayeen.

Land on Jacaylku

Jacaylku - qayb ka mid ah dhulka u dhow South reer Poland. Waxa la odhan jiray "Anti-Arctic" ama Ant-Arctic, sida antagonist ah ee Arctic ah.

Sayidka, Jacaylku qaadataa qiyaastii 50-60 daqiiqo koonfurta isbarbar.

Jacaylku - ugu, inta badan, ugu ...

Jacaylku - cidlada ugu weyn oo ugu qalalan - roobab ka yar yahay 100 mm sanadkiiba: 40-50 ka mm ee xarunta 600 mm ee waqooyiga Jasiiradda Antarctic ah. The ugu yaqaan ee wareegyada dhuuban ee Dooxooyinka qallalan ah. Roobabka aan la arkin laba milyan oo sano. Qalalan Dooxooyinka deriskiisa - Desert Atacama ah, halkaas oo ma roob wadar ahaan 400 sano. The harooyinka dooxada this - ugu cusbada leh ee dunida oo dhan. Badda Dhimatay marka la barbar dhigo iyaga - ku dhawaad cusub.

Jacaylku - cimilada adag, heerkulka ugu yar ee la diiwaan geliyey on Earth saldhiga Soviet Antarctic "Vostok" 21 July 1983 - jaray 89,6 ° C.

Jacaylku - meel of dabaylaha ugu xooga badan. ammaan ku heyso inay yihiin dabaylo katabatic. Hawada xiriir la glaciers at sare ah ee 1000 si ay u 4500 m qaboobeyso, is dulfuulan oo ay bilowdey dardar, iyagoo ku xeebta, mararka qaarkood gaarey xawaare ah 320 km / h.

Jacaylku - meelaha baraf on Earth. Kaliya 0.2-0.3% ee dusha sare ma aha daboolay baraf - buuraha Transantarctic iyo qaaradda galbeed, iyo sidoo kale xeebaha ama fatihi shaqsi iyo danbow (nunataks).

Summer koonfur ka Circle Arctic ah, meelahaas waxaa si xoog leh kululaynta, ka dibna maraysa hawada korkooda ah. Tusaale ahaan, in qallalan Valley of Victoria Land ee December 1961, waxay ahayd + 23,9 ° C

Haddaba aad u ogaato meesha dhulka ulaha magnetic yihiin.
