Njengoko ongundoqo Umhlaba wayila: isakhiwo iplanethi yethu

Ukuba iplanethi yethu nawe ngaphakathi? Njani akhiwe ongundoqo koMhlaba, kwezinye kumaxesha amandulo ukuze oku kwenzeke? Yonke le miba kudala bakhathazeka abantu. Yaye izazinzulu ezininzi babefuna ukwazi ukuba ezinzulwini? Kodwa kwenzeka ukuba isifundo konke oku kwakungelula. Nanamhlanje, nazo zonke izixhobo zale mihla zonke iintlobo zophando, phantsi kwamandla abantu izaba kukugrumba amaqula kungena ndineemfesane elithile elinesihlanu kuphela - hayi ngaphezulu. Ke amava ngokupheleleyo kwaye olubanzi nobunzulu ofunekayo kufuneka ibe umyalelo yobukhulu enkulu. Ngoko ke, singatsho ukuba izazinzulu Kufuneka sijonge phandle indlela Umhlaba kwasekwa ngumongo, esebenzisa iintlobo ngeentlobo zezixhobo ophezulu-ngqo.

Isifundo Umhlaba

Ukususela kumaxesha amandulo, abantu baye bafunda emaweni kudandalaza ngendlela yemvelo. Emaweni ezintabeni, iibhanki enkulu imilambo kunye neelwandle ... Apha uyakwazi ngokobuqu, eyayikho, mhlawumbi kwizigidi zeminyaka eyadlulayo, ukuba bagcine-GET. Yaye kwezinye iindawo ezifanelekileyo ke seligrunjiwe zamaqula. Enye yezinto ezibaluleke kakhulu kwezi - on the Kola Peninsula. kangakanani - ezilishumi elinesihlanu lamawaka eemitha. Mine ukuba abantu batyhobozele nemigodi, kunokukunceda ukufunda yangaphakathi isakhiwo Umhlaba. Core, Kakade ke, "ukufumana 'akakwazi. Kodwa ezi emigodini kunye nemithombo, izazinzulu kungaba ukubuyisa lwemizekelo yamatye, abona ngale ndlela kutshintsho yabo imvelaphi, isakhiwo kunye nokwakheka. Ngaphantsi yezi ndlela kukuba bayakwazi ukuphanda kuphela ilizwe kwaye kuphela nakumphezulu kuqweqwe lomhlaba.

Udala i iimeko ezingundoqo koMhlaba

Kodwa ngaphandle contact ukungena izazinzulu nzulu ngakumbi banceda Geophysics kunye ngezakhi - inzululwazi neenyikima kunye nokwakheka zejoloji planethi. Ngokuhlola amaza wenyikima usasazo kuvela, yaye yintoni na imentile kunye nomxholo (kuchaziwe ngokufanayo, umzekelo, awe esibhakabhakeni composition). lwazi lusekelwe kwiinkcukacha-lwazi ezithathwe - ngokungathanga ngqo - phezu iimpawu ezibonakalayo kwezinto. Kwakhona namhlanje, isifundo igalelo idata ekhoyo efunyenwe kwiisathelayithi ukujikeleza.

Ubume bale iiplanethi

Izazinzulu bakwazi ukuqonda, eshwankathela iziphumo, ukuba isakhiwo uMhlaba entsonkothileyo. Siqulathe ubuncinane kathathu ukungalingani. Xa iziko yeyona ingundoqo encinane esijikeleza omkhulu yokwaleka. I ingubo simalunga-kwesithathu ezintlanu ngumthamo opheleleyo yomhlaba. Kwaye phezu zonke kumaqweqwe amahle obhityileyo uqweqwe engaphandle yomhlaba.

Indlela emayenziwe ngayo isiqalo

Core - Central, ongaphakathi. Yahlulahlulwe yaba maleko ezininzi: bangaphakathi kunye nabangaphandle. Ngokutsho abaninzi abaphengululi mihla, umbilini ongaphakathi siluqilima, kwaye engaphandle - engamanzi (ukho zikarhulumente etyhidiweyo). Kwaye undoqo ulwandile kunene: oko: Umlinganiseli ngaphezu kokuba sesithathu ubunzima umhlaba kwi umthamo nje kwama-15. Iqondo lobushushu kwa kunokuba phezulu, ivela 2,000 ukuya 6,000 degrees Celsius. Phantsi assumptions isayensi, kwiziko Umhlaba libunjwa zentsimbi kunye nickel kwi engundoqo. Kwirediyasi ingxenye enzima - 3470 leekhilomitha. A kobuso ezikwere zeekhilomitha malunga nezigidi ezili-150, nto leyo ulingana kummandla onke amazwekazi kumphezulu komhlaba.

Njengoko ongundoqo Umhlaba wayila

Ulwazi malunga ndoqo iplanethi yethu encinane kakhulu, kwaye zifumaneka kuphela ngendlela ngqo (akukho iisampuli ezingundoqo ematyeni). Ngoko ke, ithiyori lungabonakaliswa ngombandela kuphela malunga ezingundoqo koMhlaba indlela ekwenzeka ngayo. Imbali i Umhlaba kangangamawaka ezigidi zeminyaka. Uninzi izazinzulu ngqo ingcamango yokuba umhlaba kuqala njenge homogenous kakhulu. Inkqubo yokwabiwa kwe kernel yaqala kamva. A inxalenye yawo - nickel kunye nesinyithi. Njengoko ongundoqo Umhlaba wayila? Baphele metal ngcembe wehlela ngasembindini umhlaba, uyila ngumongo. Oku kwenzeka ngenxa yokuba inxalenye enkulu yale anyibilike.

imibono ezinye

Kukho kwakhona abachasi mbono, oyingcwele umkhokele, yinto ingxabano elifanelekileyo. Okokuqala, le izazinzulu babekade isibakala wokuba bapase i intsila ngentsimbi nickel kwiziko core (iikhilomitha ezili-100). Okwesibini, ukuba sicingela ukhetho nickel nentsimbi silicates, loo Meteor ke kufuneka yenzeke kunye nokunciphisa indlela efanelekileyo. Yena, ke, walandelwa nokukhululwa imithamo emikhulu ioksijini, oyinxalenye kuxinzelelo amakhulu amawaka umoya. Kodwa ke ubungqina bokuba mandulo yemeko koMhlaba ningaswele nto. Ngoko ethunyelwe ingcamango lokusekwa yokuqala engundoqo ngexesha lokusekwa planethi.

Ngo-2015, izazinzulu Oxford bonke wanikela ingcamango ukuba undoqo uMhlaba ibandakanya uranium kwaye yemisebe. Oku ngqo kubonisa ubukho kwintsimi elide kunye nemagnethi enjalo uMhlaba, kunye nento yokuba kule mihla, iplanethi yethu ikhuphe ubushushu kakhulu ngaphezu yeengcinga kulindeleke ngaphambili zenzululwazi.
