Isijikelezi-langa sethu sinemagnethi enamandla. Iyaziwa ngegama lika ifildi yeGeomagnetic. Phakathi kweendlela ezahlukeneyo Ubume beatmosfera sifumana umaleko lowo unamandla kazibuthe uphela womhlaba. Olu luhlu lubizwa magnetosphere. Yile nto inqaku lanamhlanje malunga nayo. Siza kuthetha malunga nemagnetosphere yintoni, yenzelwe ntoni kwaye iluncedo ngantoni.
Ukuba ufuna ukwazi ngakumbi malunga nemagnetosphere, le yiposti yakho.
Yintoni umazibuthe
Njengokuba besithetha ngemagnethi ebekwe embindini weplanethi yethu, umhlaba womazibuthe womhlaba usebenza kumaza ombane. Imisinga yombane iveliswa ngu okubizwa ngokuba yimithambo yokuhambisa eyenzekayo kwindawo ye- Isiseko sangaphandle seplanethi. Kule ndawo ingaphandle sifumana uxinzelelo olukhulu lwentsimbi oluhamba kulo lonke isithuba ngenxa yomahluko kuxinano. Le mibhobho yokuhanjiswa kweenqanawa ikwenzeka nakwingubo yoMhlaba kwaye inoxanduva lokuhamba kwamazwekazi.
Ngaphandle kwento onokucinga ngayo, embindini womhlaba kukho ubushushu obuphezulu. Ukuba bekungekho ngenxa yoxinzelelo lwezixhobo, isinyithi sinokunyibilika ngokupheleleyo. Nangona kunjalo, oku akubangelwa luxinzelelo olubangelwa ngamandla omxhuzulane. Ke ngoko, kumbindi ongaphandle obekwe kumaleko weekhilomitha ezingama-2000 ubukhulu, ewe iqulethe isinyithi esityhidiweyo, i-nickel kunye nolunye ugxininiso oluncinci kwezinye izinyithi kwimeko yolwelo. Ngokufumana uxinzelelo oluncinci kunezinye izinto kunokufunyanwa.
Umahluko kubushushu obuphambili, uxinzelelo, kunye nokwakhiwa kwazo zezona zinto zibangela ukuhambisa omoya. Njengokuba kubanda, kwaye ngenxa yoko kuxinene, iyazika, umba ofudumeleyo uyenyuka. Kukwakho nomnxeba Ikoriyoli esisiphumo somjikelo womhlaba obangela ii-eddy kulo mxube wentsimbi otyhidiweyo. Ngenxa yako konke oku, imisinga yombane iveliswa ngaphakathi kwiplanethi evelisa imagnethi yomhlaba.
Zizinyithi ezihlawulisiweyo ezidlula kula masimi kwaye zenza ezazo umbane. Lo mjikelo, owaneleyo, waziwa njenge-geodynamic.
Iimpawu eziphambili
Nje ukuba sazi ukuba umhlaba uzibuthe njani, sibona ukuba umazibuthe yinto elawula umhlaba womazibuthe. Ubume beli magnetosphere buxhomekeke kwisenzo somoya welanga mzuzu ngamnye. Umoya welanga wenza ukuba icala elichaseneyo landise liye kumgama ophantse ube liwaka eliphindaphindwe lomgama womgama ophakathi kwelanga nomhlaba. Esi sibhakabhaka esikhulu semagnetosphere saziwa njengomsila wemagnethi.
Ubunzima bamandla ombane abufani kuzo zonke iindawo zomhlaba. Umzekelo, amandla ayo asezantsi eIkhweyitha kwaye aphezulu kwizibonda. Umda wangaphandle we-magnetosphere, njengakwezinye iindawo zomoya, ubizwa ngokuba yi-magnetopause. Sinokuthi ubume be-magnetosphere bunamandla kakhulu. Kungenxa yokuba ixhomekeke kakhulu kwimisebenzi yomoya welanga. Iipali zemagnetic azifani neepali zejografi. Kukho umahluko malunga ne-11 degrees phakathi kwabo. Zininzi izifundo ezithe zafunyaniswa zizazinzulu kutshintsho lwendlela ebonwa ngumazibuthe. Ukuziqhelanisa okwangoku kumantla emagnethi kungaphezulu kweekhilomitha ezingama-600 ukusuka apho yayikho kwii-XNUMXs zakuqala. Isantya sabo kufunyenwe ukuba sonyuke ngeemayile ezingama-40 ngonyaka.
Zininzi iingxelo ezimalunga nokwakheka komhlaba, ngakumbi indlela amatye abonisa ngayo, ebonisa ukuba lo mhlaba umagnethi ubuyiselwe umva ngokupheleleyo amatyeli aliqela kule minyaka ingama-500 ezigidi idlulileyo. Kwi-inversion nganye, iipali zemagnethi zihlala zikwiziphelo ezichaseneyo zeplanethi. Oku kungadala ukuba ikhampasi yesiqhelo ikhombe kwipali esemazantsi endaweni yepali yasemantla.
Ukubaluleka kwemagnetosphere
Njengoko besesitshilo ngaphambili, kukho umsebenzi welanga ekuthiwa ngumoya welanga. Lo moya welanga awuyonto ngaphandle komjelo wamasuntswana ahlawuliswa amandla e-radioactive avela elangeni. Ngombulelo kubukho bemagnetosphere sinokubona lo moya welanga ngaphandle kokonakalisa ubomi bethu. Sihlala siwubona lo moya welanga njengezibane ezisemantla kunye nezaqhwithi zomhlaba. Ukuba akunjalo kolu luhlu, kunokonakalisa zonke iinkqubo zethu zonxibelelwano ezinje ngeesathelayithi kunye neenkqubo zamaza erediyo. Ukuba kumhlaba womazibuthe womhlaba besingayi kuba nawo umoya ojikeleze umhlaba kwaye, ke ngoko, amaqondo obushushu omhlaba angahluka ngendlela efanayo nakwenzayo kumphezulu wenyanga. Koko kukuthi, kuluhlu lwamaqondo obushushu aqala kwi-123 ukuya kwi-153 degrees.
Kukho izilwanyana ezininzi ezinjengeentaka kunye neenqanawa ezikwaziyo ukubona amandla kazibuthe womhlaba kwaye zikusebenzise ukuhamba ngexesha lokufuduka. Ikwanokubaluleka okubalulekileyo kuphando lwejoloji ukuphanda ubume bamatye aphantsi komhlaba. Abavavanyi ngabo bafuna ioyile, irhasi okanye idipozithi yezimbiwa kwaye enkosi kule ndima yemagneti banokuyifumana ngokulula. Kuba la mafutha sisiseko samandla omhlaba ebantwini, siyakubona ukubaluleka kwemagnetosphere.
Ukushwankathela ngokufutshane, sinokuthi amandla kazibuthe ayimfuneko kwiplanethi ukuze ixhase ubomi.
Umahluko kumhlaba womazibuthe womhlaba
Le ntsimi yemagneti inomahluko omncinci kwisithuba seeyure ezingama-24. Umahluko ikakhulu uchaphazela ulwalathiso ikhampasi eyalathiweyo. Lo mahluko ubonakala kuphela kwishumi lesibindi kwaye ubuninzi bebonke buphazanyiswa kuphela yi-0,1%.
Nangona bengasoloko besebenza ngendlela efanayo, umahluko wemagneti uneepateni ezithile. Ipatheni ephambili lulungelelwaniso olukhoyo kunye nelanga kwaye luhlala umndilili weshumi elinanye leminyaka.
Ndiyathemba ukuba ngolu lwazi ungafunda ngakumbi malunga nemagnetosphere kunye nokubaluleka kwayo kubomi bomhlaba.
