Umehluko Phakathi Kwamadwala Angena Ngengozi Nawangaphandle Amadwala angena ngengozi, enye yezinhlobo ezintathu zamadwala eziyinhloko kanye ne-sedimentary kanye ne-metamorphic, yakha ukuqina nokupholisa kwezinto ezincibilikisiwe zedwala. Le nqubo ingenzeka ngaphansi kobuso boMhlaba noma phezu kwawo, okuholela ekuhlukanisweni kwamadwala angena ngengozi ngezinhlobo ezimbili eziyinhloko: angena ngengozi … Funda kabanzi
Indlela Yokunquma Ubudala Bezinsalela Nge-Radiometry Ukunquma ubudala bezinsalela kubalulekile ekuqondeni umlando wokuphila eMhlabeni. Enye yezindlela eziphumelela kakhulu zokuthola isikhathi sezinsalela zasendulo yi-radiometry. Le ndlela yesayensi isebenzisa izimiso zokubola kwemisebe ukuze ilinganisele ubudala bamatshe nezinsalela ngokunemba okuphawulekayo. Ku... Funda kabanzi
Ukuhlukaniswa Kwamaminerali Ngokusekelwe Ekwakhekeni Kwamakhemikhali Amaminerali, izinto eziqinile ezingokwemvelo, ezingaphili ezakha amatshe, ahlukaniswa ngezindlela ezahlukene ngokusekelwe ezimfanelweni zawo. Enye indlela eyisisekelo yokuhlukanisa la maminerali ngokwezigaba ngokusebenzisa ukwakheka kwawo kwamakhemikhali. Le ndlela yamukelwa kabanzi emkhakheni we-mineralogy ngoba inikeza okubalulekile… Funda kabanzi
Umlando Wokuguquka Kwesimo Sezulu Somhlaba Isimo sezulu somhlaba siyisimiso esiguquguqukayo nesiyinkimbinkimbi esiye sashintsha kakhulu kusukela kwadalwa iplanethi eminyakeni engaba yizigidi eziyizinkulungwane ezingu-4.6 edlule. Ukuqonda ukuguquka kwesimo sezulu somhlaba kunikeza ukuqonda okujulile ngentuthuko yokuphila kanye nezimo zemvelo eziye zakha ubuso beplanethi. Lesi sihloko sihlola … Funda kabanzi
Izindawo Ezingaphansi kanye Nencazelo Yazo Ubuso boMhlaba buyashintshashintsha futhi buhlala bushintsha, bubonakala nge-mosaic yamapuleti e-lithospheric aqinile antanta phezu kwe-asthenosphere ewuketshezi. Lawa mapuleti e-tectonic ahamba njalo, eqhutshwa amandla akhiqizwa ukushisa kwangaphakathi koMhlaba. Enye yezinqubo ezithakazelisayo nezibaluleke kakhulu ku… Funda kabanzi
Izici Ezithonya Ukuguguleka Komhlabathi Ukuguguleka komhlabathi kuyisimo se-geological lapho ungqimba oluphezulu lomhlabathi lususwa khona amandla emvelo njengomoya namanzi. Ngenkathi izinga elithile lokuguguleka komhlabathi lenzeka ngokwemvelo, imisebenzi yabantu kanye nezimo ezithile zemvelo kungenza imiphumela yakho ibe mibi kakhulu. Ukuqonda izici eziyinhloko ezithonya ukuguguleka komhlabathi kubalulekile... Funda kabanzi
Indlela Ukuzamazama Komhlaba Okwenzeka Ngayo: I-Symphony Engaphansi Komhlaba Yokugcwala Okungaphumuli Komhlaba Umsindo ongaphansi kwezinyawo zethu, ukushaqeka okungazelelwe okuthumela izakhiwo zinyakaze futhi abantu bephuthuma ukuphepha—ubufakazi bamandla amakhulu asebenzayo eMhlabeni. Kodwa-ke, yini ebangela lezi zenzakalo zokuzamazama komhlaba? Kwenzeka kanjani ukuzamazama komhlaba? Uhambo lwethu ngokusebenzisa izindlela zalezi zemvelo … Funda kabanzi
Umehluko Phakathi Kwe-Magma Ne-Lava Ezweni elimangalisayo le-geology, umsebenzi we-volcanic ungenye yezinto ezikhanga kakhulu ezisikhumbuza ngesimo soMhlaba esiguquguqukayo. Okubalulekile ekuqondeni ukuqhuma kwe-volcanic yimibono emibili eyisisekelo: i-magma ne-lava. La magama avame ukusetshenziswa ngokushintshana engxoxweni evamile, kodwa anezincazelo ezihlukile futhi … Funda kabanzi
### Ama-Plate Tectonics kanye Nomthelela Wawo Ama-Plate tectonics ayimfundiso eyisisekelo kweze-geology echaza ukuguquguquka kwegobolondo langaphandle loMhlaba, i-lithosphere, elihlukaniswe ngamapuleti amaningana ahambayo. Lawa mapuleti antanta phezu kwe-asthenosphere ewuketshezi ngaphansi kwawo. Ukusebenzisana kanye nokunyakaza kwala mapuleti kwakha iplanethi yethu ngezindlela eziningi, ezivame ukuba yisimangaliso, … Funda kabanzi
### Isakhiwo Sangaphakathi Somhlaba Umhlaba, iplanethi yethu yasekhaya, uyisimangaliso sobunzima be-geological kanye nemvelo. Ubuso bawo buwubufakazi bezinqubo eziguquguqukayo ezisebenza ngaphansi kwezinyawo zethu, futhi lezi zinqubo zilawulwa yisakhiwo esingaphakathi. Isakhiwo sangaphakathi soMhlaba asibonakali kithi ngqo, kodwa ngezindlela ze-geophysical kanye … Funda kabanzi
