I-GEOLOGY

Indlela Yokuhlaziya Amasampula Edwala Lentaba-mlilo Ukuhlaziya amasampula edwala lentaba-mlilo kuyisinyathelo esibalulekile ekuqondeni umlando wokuqhuma, indawo yokwakheka, ukwakheka kwe-magma, kanye nezinsizakusebenza ezingaba khona kanye nezingozi ze-geological esifundeni. Amadwala entaba-mlilo ahlinzeka "ngomlando" wezinqubo ezenzeka ngaphansi kobuso boMhlaba—kusukela ekubunjweni kwamaminerali kanye nokuqina okusheshayo kuya ekusebenzelaneni namanzi noma nomoya. Lesi sihloko sixoxa... Funda kabanzi

Kuyini i-Transform Plate Tectonics? I-Plate tectonics iyinkolelo-mbono enkulu kwisayensi yomhlaba echaza ukuthi ungqimba loMhlaba (i-lithosphere) lwakhiwe ngamapuleti amakhulu amaningi ahamba kancane phezu kwengqimba yepulasitiki ngaphansi (i-asthenosphere). Ukunyakaza kwala mapuleti kudala izenzakalo ezahlukahlukene ze-geological njengokuzamazama komhlaba, izintaba-mlilo, izintaba-mlilo, kanye nokwakheka kwephansi lolwandle. Enye ye... Funda kabanzi

Ukubaluleka Kwe-Geology Ekwakhiweni Kwezakhiwo Nokuhlelwa Kwamadolobha I-Geology ivame ukuqondwa njengokutadisha amatshe, inhlabathi, kanye nezinqubo zemvelo ezibumba uMhlaba. Kodwa-ke, indima yayo idlulela ngale kwendawo yezemfundo. Ekwakhiweni kwezakhiwo nasekuhlelweni kwamadolobha, i-geology iyisisekelo esibalulekile sokuqinisekisa ukuthi izakhiwo zimi ngokuphephile, ingqalasizinda isebenza ngokwethembeka, futhi amadolobha athuthuka ngendlela eqhubekayo. Ukwehluleka okuningi kokwakhiwa—imifantu yesakhiwo, ukwehla… Funda kabanzi

Indlela Imithombo Yemvelo Evuselelekayo Ehluke Ngayo Emithombo Yemvelo Engavuseleleki Imithombo yemvelo iyinoma yini enikezwa yimvelo futhi ingasetshenziswa abantu ukuhlangabezana nezidingo zabo, kusukela emandleni nokudla kuya ezintweni zokusetshenziswa zezimboni kanye nezidingo zansuku zonke. Kodwa-ke, akuzona zonke izinsiza zemvelo ezinekhono elifanayo lokuvuselela. Ezinye zingavuselelwa ngokwemvelo ngesikhathi esifushane… Funda kabanzi

Izici nezinhlobo zama-stalactites. Ama-stalactites angenye yemihlobiso yemvelo evelele kakhulu etholakala emihumeni ye-limestone (emihumeni ye-karst). Avame ukubonwa njengezimo "ezinameva" ezilenga ophahleni lomhume, ngezinye izikhathi zicacile njengeqhwa, ngezinye izikhathi zibe nsundu ngokukhanyayo, futhi ngezinye izikhathi zibonakala zingqimba njenge-wax encibilikisiwe. Ngaphandle kobuhle bazo, ama-stalactites aphethe ulwazi olubalulekile mayelana... Funda kabanzi

Izindlela ze-Petrographic ekuHlaziyweni kwamadwala I-Petrographic iyigatsha le-geology eligxile ekuchazeni nasekuchazeni amadwala ngokusekelwe ekwakhekeni kwawo kwamaminerali, ukuthungwa, kanye nesakhiwo sangaphakathi. Izindlela ze-Petrographic zingenye yezindlela ezibaluleke kakhulu zokuhlaziya amadwala ngoba zisivumela ukuthi "sifunde" umlando wokwakheka kwamadwala ngokubuka okuqondile, ikakhulukazi ngosizo lwe-microscope ehlukanisayo. Kusukela kuma-igneous kuya kuma-sedimentary kuya kuma-metamorphic rocks, … Funda kabanzi

Ayini Amapuleti E-Oceanic Nezimpawu Zawo? Amapuleti e-Oceanic angenye yezingxenye eziyinhloko ze-lithosphere yoMhlaba (ungqimba olungaphandle oluqinile loMhlaba), olutholakala phansi kolwandle. I-lithosphere ngokwayo ihlukaniswe ngamapuleti amaningana amakhulu namancane aqhubeka ehamba kancane phezu kongqimba olungaphansi, oluyipulasitiki, i-asthenosphere. Ukunyakaza kwala mapuleti kuyimbangela eyinhloko... Funda kabanzi

Umqondo We-Hydrosphere Nomthelela Wayo Emkhathini I-hydrosphere yizo zonke izingxenye zamanzi ezitholakala eMhlabeni, okuhlanganisa amanzi asesimweni soketshezi, esiqinile, nesinomoya. Ihlanganisa izilwandle, imifula, amachibi, amaxhaphozi, amanzi angaphansi komhlaba, amaqhwa, umhwamuko wamanzi womoya, ngisho nomswakama ogcinwe enhlabathini nasemadwaleni. Nakuba amanzi emboza "kuphela" cishe u-71% wobuso boMhlaba, indima yawo idlulela ngale... Funda kabanzi

Ubudlelwano Phakathi Kwe-Geology Ne-Climatology I-Geology kanye ne-climatology kuvame ukufundwa njengamagatsha amabili ahlukene esayensi: i-geology igxila ezintweni zokwakha, isakhiwo, kanye nomlando woMhlaba, kuyilapho i-climatology ifunda ngesimo sezulu sesikhathi eside kanye namaphethini esimo sezulu. Kodwa-ke, empeleni, lokhu okubili kuxhumene kakhulu futhi kwakha ubudlelwano obuhambisanayo. Izinqubo ze-geology zingashintsha isimo sezulu, futhi okuphambene nalokho. … Funda kabanzi

Iyini Insimu Ye-Geomagnetic Nendima Yayo? Insimu ye-geomagnetic "ingubo" engabonakali yamagnetic ezungeze uMhlaba. Nakuba singenakuyibona ngqo, ukuba khona kwayo kungazwakala ngekhampasi, enenaliti evame ukukhomba enyakatho-eningizimu. Le nsimu idlala indima ebalulekile ekugcineni impilo eMhlabeni, ithonya ukuzulazula, futhi iyisihluthulelo sokuqonda amandla... Funda kabanzi
