Ukubaluleka Kwamadwala Omthombo Kumjikelezo Wedwala Umjikelezo wedwala uyinqubo yemvelo eqhubekayo ekhombisa indlela amadwala eMhlabeni akha ngayo, ashintsha ngayo, aqhekeke ngayo, bese eguquka ngezindlela ezahlukene. Ngaphakathi kwale nqubo ebonakala ilula, kunomqondo owodwa oyinhloko ovame ukunganakwa ngokujulile: idwala lomthombo. Idwala lomthombo lingaqondwa njenge… Funda kabanzi
Indlela Yokuhlola Amandla Emithombo Yamaminerali Ukuhlolwa kwamandla emithombo yamaminerali kuwuchungechunge lwemisebenzi yesayensi, yezobuchwepheshe, neyezomnotho yokunquma ukuthi indawo inezimbiwa zamaminerali ezibalulekile, ubukhulu bazo, ukulula kwazo kokumba, nokuthi imisebenzi yokumba izosebenza kahle ngokwezimali futhi iyamukeleka yini ngokwemvelo nangokwenhlalo. Le nqubo ayikwazi... Funda kabanzi
Iyini i-El Niño kanye Nomphumela Wayo Ku-Geology? I-El Niño ingenye yezenzakalo zesimo sezulu ezinethonya elikhulu eMhlabeni. Nakuba kuvame ukuxoxwa ngazo esimweni sezulu esibi kakhulu—njengesomiso esihlala isikhathi eside, izikhukhula, noma izinkathi ezishintshashintshayo—i-El Niño nayo inemiphumela ebalulekile engaqondile ezinqubweni ze-geology. I-Geology ifunda ngamatshe, izakhiwo eziqinile, izintaba-mlilo, kanye nokwakheka komhlaba... Funda kabanzi
Izinhlobo Zamadwala Acwebezelayo Ngokusho Kokuqukethwe Kwamaminerali Amadwala acwebezelayo angamadwala akhiwe ukupholisa kanye nokukristala kwe-magma noma i-lava. Le nqubo ingenzeka ngaphansi kobuso boMhlaba (ukungenelela/i-plutonic) noma ebusweni boMhlaba (ukuqhuma/intaba-mlilo). Nakuba amadwala acwebezelayo evame ukuhlukaniswa ngokusekelwe endaweni yawo yokwakheka noma ukuthungwa, enye yezindlela ezibaluleke kakhulu zokuhlukanisa ku-geology isekelwe kokuqukethwe kwawo kwamaminerali.

Umphumela Wezinga Lokushisa Nokucindezela Ekwakhekeni Kwamaminerali Ukwakheka kwamaminerali kuyinqubo yejiyoloji eyenzeka isikhathi eside kakhulu futhi ethonywa izici ezahlukene zomzimba nezamakhemikhali. Phakathi kwezici ezibaluleke kakhulu izinga lokushisa nokucindezela. Lezi zici zilawula ukuzinza kweminerali, zinqume izinhlobo zamaminerali angakheka, futhi zilawule ukuguqulwa kwamaminerali amadala abe amasha. Funda kabanzi
Ziyini Izinhlayiya Ezingama-Anticline kanye Nezinhlayiya Ezihambisanayo Ku-Geology Yesakhiwo? Ku-geology yesakhiwo, esinye sezihluthulelo zokuqonda umlando wokuguqulwa koqweqwe loMhlaba ukuqaphela nokuhumusha izinhlayiya. Izinhlayiya zakha lapho izendlalelo zamadwala ezaziyisicaba ngaphambili zicindezelwa, zichekwa, noma zihlanganiswa la mandla, okubangela ukuba zigobe. Izinhlobo ezimbili ezivame kakhulu zezinhlayiya yilezi... Funda kabanzi
Indlela Yokuthola Umthombo Wokungcola Kwamanzi Angaphansi Komhlaba Amanzi angaphansi komhlaba angomunye wemithombo yamanzi ebaluleke kakhulu empilweni yansuku zonke, ikakhulukazi emiphakathini ethembele emithonjeni yokuphuza, ukupheka, ukugeza, kanye nokunisela. Kodwa-ke, ikhwalithi yamanzi angaphansi komhlaba ayiphephile ngaso sonke isikhathi. Ukungcola kwamanzi angaphansi komhlaba kungenzeka buthule, kunzima ukukubona, futhi kuvame ukubonwa kuphela ngemva kokuba imiphumela yezempilo ivele... Funda kabanzi
Ubudlelwano phakathi kwe-Geology ne-Earth Physics I-Geology ne-Earth physics (geophysics) yimikhakha emibili ehlobene kakhulu ekuqondeni iplanethi esiphila kuyo. I-Geology igxile ezintweni ezakha uMhlaba, umlando wawo, kanye nezinqubo ezibumba ubuso bawo kanye nengaphakathi lawo. Okwamanje, i-Earth physics isebenzisa izimiso ze-physics ukuphenya isakhiwo, izakhiwo, kanye nokuguquguquka koMhlaba… Funda kabanzi
Izindlela Zokudonsela Emhlaba Ekuhloleni Kwezwe Izindlela zokudonsa amanzi ziyizindlela ze-geophysical ezisebenzisa ukuhlukahluka kokusheshisa kwamandla adonsela phansi eMhlabeni ukuze zichaze izimo zangaphansi komhlaba. Ekuhloleni kwezwe—kungakhathaliseki ukuthi kwenziwa ngamaminerali, uwoyela negesi, ukushisa komhlaba, noma izifundo zesakhiwo sesifunda—ukudonsa amanzi kudlala indima ebalulekile ngoba kunganikeza isithombe sokwehluka kobuningi bamadwala ngaphandle kwesidingo sokumba...

Indlela Isakhiwo Somhlaba Esithinta Ngayo Imicimbi Yemvelo Umhlaba awuyona nje ibhola elikhulu ledwala "elithule" esikhaleni. Ngaphansi kobuso bawo obubonakala buzinzile kunesimiso esiguquguqukayo, esinezingqimba eziningi: esinye esiqinile, esinye sepulasitiki, esifana nenhlama ejiyile, kanye nengaphakathi elishisayo kakhulu. Lesi sakhiwo sangaphakathi silawula indlela amandla okushisa ahamba ngayo, indlela amapuleti... Funda kabanzi
