Ngokuqinisekileyo wakha wazibuza wenziwa njani umhlaba. Ukuba ungumKatolika, baya kukuxelela ukuba uThixo wadala umhlaba nazo zonke izinto eziphilayo ezihlala kuwo. Inzululwazi, kwelinye icala, iphande iminyaka emininzi ngemvelaphi yoMhlaba kunye nendlela eguquke ngayo zonke ezi zigidi zeminyaka. Kule meko, kuya kufuneka uthathele ingqalelo Ixesha lejoloji, kuba isikali sendaleko yoMhlaba sibalekela kwinqanaba lomntu.
Kweli nqaku siza kuchaza nzulu ukuba umhlaba wenziwa njani kwaye uguquke njani unanamhla.
Ubume boMhlaba
Imvelaphi iplanethi yethu enayo ivela i-nebula uhlobo lweprotosolar. Ivela kwi-4600 yezigidigidi zeminyaka eyadlulayo. Ngelo xesha lokudala, zonke iiplanethi zazikwimeko yothuli ephantsi. Oko kukuthi, zazingafakwanga kwaye zazingenamoya okanye ubomi (kwimeko yoMhlaba). Ekuphela kwento eyenze ukuba indalo yobomi eMhlabeni ibekho ngumgama ogqibeleleyo ukusuka eLangeni.
Yobukho belifu legesi elibangele ukungqubana kunye namasuntswana othuli ahamba emva koko inkqubo yelanga Ukuhambahamba ujikeleze kuqhushumbo olukhulu lwenziwa. La masuntswana ayejiya kwinto esiyaziyo namhlanje njengommandla weMilky Way obizwa ngokuba yiEagle Nebula okanye iintsika zendalo. Lawo mafu mathathu othuli kunye negesi ayanceda ukuvelisa iinkwenkwezi ezintsha xa zisiwa phantsi komxhuzulane.
Ubunzima bamasuntswana othuli afingqiwe kwaye ilanga ladalwa. Ngexesha elifanayo nezinye iiplanethi ezenza inkqubo yelanga zenziwa, ngokunjalo neplanethi yethu ethandekayo.
Yile ndlela uMhlaba owenziwe ngayo
Umthamo omkhulu wegesi njengoko kunjalo kwiiplanethi Umbhali y Saturn sasisekuqaleni. Njengoko ixesha lihambile, yaba yimeko eqinileyo ngokupholisa uqweqwe. Oku kudalwa koqweqwe lomhlaba kwakubangela okwahlukileyo maleko ongaphakathi woMhlabaa, kuba i-nucleus ayiqinanga. Olunye uqweqwe lwaluthatha izinto ezikhoyo ngoku esizaziyo njenge Amacwecwe eTectonic.
Isiseko soMhlaba lulwelo oluqulathe intsimbi etyhidiweyo kunye neeminerali ze-nickel kunye nemagma. I-volcano ezazenziwe ngelo xesha zazisebenza kwaye zazikhupha udaka kunye nesixa esikhulu segesi kwaye zenza umoya. Ukwenziwa kwayo bekutshintsha kule minyaka idlulileyo ukuya kubume bayo bangoku. Iintaba-mlilo zizinto eziphambili ekubunjweni komhlaba kunye nokuma kwawo.
Ukuyilwa komoya woMhlaba
Umoya asiyonto eyakheke ngesiquphe okanye ngobusuku. Zininzi izinto ezikhutshwayo ezivela kwiintaba-mlilo ezikhutshiweyo kumawaka eminyaka ukukwazi ukwenza ubume esinabo namhlanje kwaye, enkosi kuyo, sinokuphila.
Isiseko somoya wokuqala sasenziwe ngehydrogen kunye ne helium (ezi zimbini iigesi zininzi kakhulu ngaphandle). Kwisigaba sesibini sophuhliso lwayo, xa inani elikhulu leemeteorites labetha uMhlaba, umsebenzi wentaba-mlilo waqiniswa ngakumbi.
Iigesi ezibangelwe zezi ziqhushumbisi ziyaziwa njengomoya wesibini. Ezi gesi ubukhulu becala yayingumphunga wamanzi kunye nekhabhon dayoksayidi. Iintaba-mlilo zikhuphe iigesi ezininzi ezinesalfure, ke umoya ojikeleze umhlaba wawuyityhefu kwaye akukho mntu wayenokusinda kuwo. Xa zonke ezi gesi emoyeni zijiyile, imvula yaveliswa okokuqala. Kulapho, ukusuka emanzini, Iintsholongwane zokuqala ze photosynthetic zaqala ukuvela. Iibhaktheriya ezenza i-photosynthesis zikwazile ukongeza ioksijini kwimeko enetyhefu.
Enkosi ngokunyibilikiswa kweoksijini kwiilwandle nakwiilwandlekazi, ubomi baselwandle bunokubakho. Emva kweminyaka yokuzivelela kwezinto kunye neminqamlezo yemfuza, ubomi baselwandle bakhula kakhulu kangangokuba baphelela phesheya ukuze baphile emhlabeni. Kwinqanaba lokugqibela lobume bomoya, ukwakheka kwayo sele kunjalo namhlanje. I-78% ye-nitrogen kunye ne-21% yeoksijini.
I-Meteor shower
Umhlaba ngelo xesha wahlaselwa ngamatye emeteorite amaninzi abangela ukwenziwa kwamanzi kwimeko yolwelo kunye neatmosfera. Ukusuka apha kwavela ithiyori yokuba Izazinzulu ziyibiza ngokuba yiTheyosiyori. Kwaye kukuba ukusuka ekutshatyalalisweni, inkqubo ene-entropy enkulu inokuvelisa ubomi kwaye ihambele kwinqanaba lokulingana esinalo ngoku.
Kwiimvula zokuqala ezithe zenzeka ezona ndawo zinzulu zamaxolo zenziwa ngenxa yobuthathaka obabunabo ngelo xesha phambi kobunzima bamanzi. Yile ndlela yenziwa ngayo i-hydrosphere.
Ukudityaniswa kwazo zonke izinto ezenziweyo zomhlaba kwenza ukuba ubomi buphuhle njengoko sisazi. Okuninzi kophuhliso lwethu kungenxa yomoya. Nguye osikhuselayo kwimitha yelanga eyingozi, ukuwa kweemeteorite kunye neenkqwithela zelanga eziza kutshabalalisa yonke imiqondiso kunye neenkqubo zonxibelelwano zehlabathi.
Iiplanethi ezingqonge iinkwenkwezi kunye nokwakheka kwazo ziyaqhubeka ukuxoxwa kwihlabathi liphela. Nangona kunjalo, inkqubo ebandakanyekayo ekwakheni iplanethi ayikacaci ncam. Ingxaki kukuba, njengoko benditshilo ekuqaleni kwenqaku, ixesha le-geological ligxile apha hayi kubungakanani bomntu. Ke ngoko, ukwenziwa kweplanethi ayisiyonto esinokuyifunda okanye siqwalasele inkqubo yayo. Kufuneka sithembele kubungqina besayensi nakwimibono.
Ndiyathemba ukuba ngolu lwazi ungayiqonda ngcono indlela uMhlaba owenziwe ngayo. Inkolelo yomntu ngamnye ngokubhekisele kuqeqesho lwasimahla, apha sinika nje inguqulelo yesayensi kuba iyibhlog yesayensi.
