Nakuba ulwazi selutholakale iminyaka ku- Ukwakhiwa Kwengqikithi Yomhlaba, iqiniso liwukuthi ukwakheka kwayo okunembile nalokho okutholakala lapho ngisho nanamuhla kuyimfihlakalo, nokho sikulethela lonke ulwazi olwaziwayo mayelana neNkathi Yangaphakathi Yomhlaba khona lapha.
Yini i-Earth Core?
Abantu benze inqubekelaphambili enkulu uma kuqhathaniswa namakhulu eminyaka edlule, namuhla izinguquko noguquko alushintshi kuzo zonke izici zokuphila, isikhathi siyahamba futhi asimi, sesikwazile nokufika enyangeni futhi sisezinhlelweni zokukwazi ukufinyelela kwamanye amaplanethi. , amathuba alokho esingakuzuza esikhathini eside awapheli.
Kodwa-ke, enye yezimfihlakalo ezinkulu zomhlaba ingaphansi kwezinyawo zethu, iqala ngamakhilomitha angaba ngu-3.000 ngezansi futhi iyaqhubeka iqhubekela phambili ize ifinyelele enkabeni yawo futhi ngenxa yalokho isikhungo soMhlaba ngamakhilomitha angu-6.000, ukunemba kakhudlwana, sihambisana 32% yayo.
Akukwazanga ukufinyelela kuso ngenxa yokuthi akunakwenzeka ngokomzimba, njengoba kucatshangwa ukuthi emazingeni okushisa angafinyelela ku-6.700 ° C, kusobala ukuthi ukushisa umzimba womuntu ongakwazi ukumelana nakho, okwengeza kulokhu kukhona nokucindezela okukhiqizwayo. ngenkundla kazibuthe engavumeli noma iyiphi imoto ukuthi iqhubekele phambili kakhulu.
Okuphansi kakhulu umuntu akwazile ukukufinyelela kube intuthuko enkulu eyenziwe eRussia ngabacwaningi ngezinjongo zesayensi, le phrojekthi yayisekelwe ekukwazini ukufinyelela amamitha angu-15.000, kodwa izinga lokushisa laliphindwe kabili kunalelo obekulindelekile nangemva kwezinkinga ezithile ezibangele. iphrojekthi ezobambezeleka, bacishe bakwazi ukufinyelela kumamitha ayi-12.300 ngaphansi koqweqwe lomhlaba, ngo-2008 iphrojekthi yakhanselwa ngenxa yokuntuleka kwesabelomali.
Umsuka Womgogodla Womhlaba
Umhlaba waba nemvelaphi yawo njengokuhlanganiswa kwezingxenye ezihlukahlukene zesikhala, yonke into yaqala njengenqwaba yokushisa okwathi ngokuhamba kwesikhathi yanikeza isimo kuzo zonke izingqimba esizazi kakade namuhla, izinto ezisindayo zajula, zikwazi ukulondoloza ukushisa emkhatsini. futhi izinto eziminyene kancane zalondolozwa ngaphandle, zaze zaba izingqimba futhi zakha Isakhiwo somhlaba.
Ukwakhiwa Kwengqikithi Yomhlaba
Kuye kwaphakanyiswa imibono eminingi mayelana nokuthi yini Ukwakhiwa Kwengqikithi Yomhlaba, kodwa ngendlela efanayo, abaningi babo kuye kwadingeka baphikiswe, njengoba kwenziwa ngaleso sikhathi ngenkolelo-mbono yokuthi isikhungo soMhlaba senziwa ngegolide njengoba ukuminyana kwalo kusondelene kakhulu nalesi sakhi, ngaphandle Nokho, ososayensi abaningi bavuma ukuthi umongo ikakhulukazi insimbi ehlanganiswe nezinye izinsimbi, kodwa ngamanani amancane.
Lokhu kucabanga kokugcina kusekelwe ngaphezu kwanoma yini ekucabangeni okunengqondo, njengoba enye yezinto ezitholakala ngobuningi endaweni yonke insimbi, kwaphenywa ukuthi isisindo esiningi somhlaba wonke sitholakala enkabeni yomhlaba nangaphezulu abukho. t insimbi eningi njengoba izibalo zingaphakamisa, ngakho-ke lindela ukuthi iningi lale ngqondo ligxile emnyombweni.
Kukhona futhi izakhi eziningi ezingavamile ukubonakala ku-crust ne-mantle, enye yazo ingaba yisulfure, ngoba kunengxenye encane kakhulu yale ngxenye ngaphandle komgogodla.
Okuthakazelisa kakhulu kwe Ukwakhiwa Kwengqikithi Yomhlaba kwakuyizinqubo okwakudingeka zidluliselwe kuzo ukuze kuqhamuke le mibono kanye nalokho esingakubheka njengolwazi olunembe kakhudlwana, ikakhulukazi ukwaziswa kwatholakala ngokubhekwa okwenziwa ocwaningweni lokuzamazama komhlaba, ngenxa yalokho okunganikezwa ukubala cishe kwe Ubukhulu bomhlaba.
Konke ukunyakaza kwangaphakathi komhlaba kukhipha amagagasi asakazeka emhlabeni wonke futhi ngokuqinisekile kwezinye izifunda kuzwakala kakhulu kunezinye, lapho ukunyakaza kucishe kungabonakali.
I-nucleus yangaphandle
Ingxenye yolwazi ebaluleke kakhulu etholwe ekudlidlizeni okurekhodwe ukuzamazama komhlaba kusukela ngawo-30s ukuthi amagagasi ayashintsha njengoba ehamba ngesakhiwo seplanethi futhi okwenza ukudlidliza kwezinye izifunda kuhluke, kusukela Ukwazi lokhu, ngawo-60 a. kwabhalwa ukuzamazama komhlaba okubaluleke kakhulu okwafika kwakhipha uhlobo oluthile lwamagagasi ososayensi bakwezinye izingxenye zomhlaba ababelulindile, kodwa aluzange lufike.
Ngemva kwesikhathi esithile, kwenziwa uphenyo oluningi ngalesi senzakalo, kwafinyelela esiphethweni sokuthi amagagasi awazange asakazwe ngenxa yokuthi ayengakwazi ukuhamba oketshezini olwakhiwe ungqimba lwangaphandle lwe-nucleus. I-radius yenkango yangaphandle ingamakhilomitha angu-2.250 futhi yakhiwe ngensimbi encibilikisiwe, ngenxa yamazinga okushisa aphakeme, engakwazi ukuqina.
Ingqikithi Yangaphakathi
Ososayensi bayichaza njengendilinga enkulu indawo yayo engaba amakhilomitha angu-1.255, inzima kakhulu futhi iyashisa njengoba izinga layo lokushisa lingadlula ku-5.500 ° C. Kunokwehlukana okubalulekile phakathi kwama-nuclei amabili aziwa ngokuthi i-Bullen discontinuity, okuvumela le mbulunga ukuthi ihambe ngokuzimele kuwo wonke umhlaba futhi ucwaningo lwakamuva lubonisa ukuthi inesivinini esithe ukudlula iplanethi.
Ekuqaleni lokhu kwabaxaka kakhulu abacwaningi, lapho bethola ukuthi ungqimba lwangaphakathi lwe-nucleus lwaluqinile futhi alulona uketshezi njengolunye, kamuva baqonda ukuthi kwakungenxa yokuthi, nakuba izinga lokushisa kulolu ungqimba lalizofinyelela eqophelweni lokuncibilikisa izinsimbi, kodwa kwakungeyona into engavamile. ingcindezi engaphakathi kwengaphakathi inamandla kangangokuthi ayivumeli lezi zakhi ukuba zihlukane.
Inkambu kazibuthe
Umnyombo wangaphandle ubaluleke kakhulu, njengoba ukunyakaza kwensimbi esimweni sayo esiwuketshezi kudala ukushaja kagesi okunwebekayo, ngosizo lwezinye izinsimbi ezitholakala emhlabeni nazo ezikhiqiza ukushaja okufanayo kodwa ngokwezinga elincane, wonke la mandla alawulayo. ukufinyelela emkhathini okwenza insimu kazibuthe.
Ingaphakathi elingaphakathi lingase futhi libangele lo mphumela, njengebhola elikhulu elakhiwe ngezinsimbi ezinozibuthe kakhulu, nokho izinga lokushisa kunkambo yangaphandle liphakeme kangangokuthi insimbi ilahlekelwa ngokuphelele amandla ayo kazibuthe.
Ukubaluleka Komgogodla
Njengezinto eziningi, izinto zokwakha kanye nezinqubo ezikhona emhlabeni, Ukwakhiwa Kwengqikithi Yomhlaba inokubaluleka okukhulu, ngoba ayibalulekile empilweni yomuntu kuphela, kodwa naso kanye isakhiwo sePlanethi Yomhlaba, ngoba i-nucleus inguzibuthe omkhulu oheha zonke izingxenye okwakhiwa ngazo umhlaba futhi ikakhulukazi yiwo owanikeza. imvelaphi eya ekwakhiweni kwezingqimba ngenqubo ebizwa ngokuthi ukuhlukaniswa kwamaplanethi.
I-magnetic field, okuwumphumela we-nucleus, yiyona evumela ukuba khona komkhathi ovikela ukuphila emhlabeni ngokunciphisa ukungena kwamandla anamandla akhiqizwa imisebe ye-ultraviolet yelanga, iyakwazi futhi ukumisa imithelela yanoma iyiphi into yasemkhathini engena ku-orbit nomhlaba
Lo mkhakha uvumela futhi ukusetshenziswa okwaziwayo kwekhampasi, eyasungulwa ekhulwini leshumi nambili futhi isivumela ukuba siziqondise sisebenzisa izinaliti ezinozibuthe ezikhomba kuzo zombili izigxobo, lokhu kusungulwa kobuhlakani kwavumela amatilosi ukuba azi ukuthi ayehamba ngakuphi. olwandle olukhulu, okuwukuphela kwendawo lapho ikhampasi ingasebenzi kahle kusezigxotsheni.
Ngisho nezilwane eziningi ziyakwazi ukuzitholela indawo ngenxa yamandla kazibuthe, ziqondiswa yiwo zingasuka endaweni ethile ziye kwenye futhi zifuduke lapho kudingeka. Ukuphendukela empilweni yezitshalo, kunezinqubo zesayensi ezibonisa ukuthi izitshalo zingakha futhi zikhule ngokushesha kakhulu ngaphansi kokuvikelwa kwensimu.
Isibonelo esicacile sokubaluleka kwamandla kazibuthe empilweni yomuntu yisifo esibizwa ngokuthi ukugula komkhathi futhi senzeka ohambweni lokuqala lokuya emkhathini, njengoba umzimba womuntu usujwayele ukuphila emhlabeni kangangokuthi lapho abahambi bephumela emkhathini , wahlushwa ezinye izifo futhi umzimba waqala isigaba sokuwohloka, okwenza ezinye izitho ezibalulekile zingabi namsebenzi.
Bathe le miphumela ibangelwa ukuthi awekho amandla kazibuthe aguqulelwe ukuphila komuntu emkhathini futhi ukuze banciphise le miphumela kwadingeka bakhe insimu ezungeze umkhumbi eyayingasebenzi kahle ngo-100%, kodwa yafeza umsebenzi wayo futhi yabambezela ukuqhubeka kwalokhu. imiphumela.
Singaphetha ngokuthi umnyombo wasemhlabeni, konke ukwakheka kwawo kanye nemisebenzi yawo kubaluleke kakhulu ukuze ukuphila kwakheke eplanethini engumhlaba, umhlaba njengoba siwazi njengamanje ngeke kwenzeke ngaphandle komgogodla wangaphakathi nangaphandle. Okwanele nje ukukutshela ukuthi indawo esikuyo manje ngeke ibe yize, mhlawumbe esinye isikhala esingenalutho endaweni yonke.
