Kungani Kuqhuma Izintaba-mlilo? Izintaba-mlilo zingenye yezimangaliso zemvelo ezikhanga kakhulu futhi ezesabekayo. Ubuhle bazo buvame ukuhlanganiswa namandla azo okubhubhisa. Ngemuva kwalesi simo semvelo esimangalisayo kukhona inqubo yesayensi eyinkimbinkimbi. Umbuzo wokuthi kungani kuqhuma izintaba-mlilo uvame ukuvusa ilukuluku lethu. Kulesi sihloko, sizoxoxa ngokuningiliziwe... Funda kabanzi
Iyini iTheory of Plate Tectonics? ITheory of Plate Tectonics ingenye yezinkolelo-mbono zejiyoloji ezibaluleke kakhulu neziyisisekelo ekuqondeni amandla oMhlaba. Le mbono ichaza ukuthi ungqimba loMhlaba lwakhiwe kanjani ngamapuleti ahlukahlukene e-tectonic ahamba futhi axhumana omunye nomunye ngaphezu kwengubo encibilikisiwe kancane. Lo mqondo awubalulekile nje kuphela kwisayensi kodwa futhi uthonya… Funda kabanzi
Inqubo Yokwakhiwa Kwamalahle Isingeniso Amalahle ayi-fossil fuel edlala indima ebalulekile ekuhlinzekweni kwamandla emhlabeni. Nakuba amalahle ebe ngumgogodla wemboni iminyaka engaphezu kwamakhulu amabili, abaningi abakaqapheli ngenqubo ende nengokwemvelo edingekayo ukuze kwakhiwe la mafutha. Lesi sihloko sizochaza...

Ukubaluleka Kocwaningo Lwenhlabathi Kwezomhlaba Ucwaningo lwenhlabathi lungenye yezici eziyisisekelo nezibaluleke kakhulu zezifundo zejoloji. Inhlabathi iwungqimba olungaphandle kakhulu loMhlaba futhi idlala indima ebalulekile ezimisweni zemvelo kanye nokuphila kwabantu. Njengoba kunikezwe izinzuzo eziningi ezinikezwa yinhlabathi, ucwaningo kulo mkhakha lubalulekile ekuqondeni isakhiwo sayo, ukwakheka kwayo, kanye nezinqubo ezenzeka ngaphakathi... Funda kabanzi
Uyini Umjikelezo Wedwala? Isingeniso Umjikelezo wedwala umqondo wejiyoloji ochaza izinguquko eziguquguqukayo neziqhubekayo ezidlula amadwala ngaphakathi kongqimba loMhlaba. Amadwala awahlali eqinile ngesimo esisodwa; ahlala eguquka kusukela kolunye uhlobo aye kolunye ngezinqubo ezahlukahlukene, okuhlanganisa ukuguguleka, ukuguguleka, ukuqina, ukushisa, kanye nokupholisa. Lesi sihloko sizoxoxa ngencazelo yomjikelezo wedwala... Funda kabanzi
Umehluko Phakathi Kwamadwala Angena Ngengozi Nawangaphandle Amadwala angena ngengozi awuhlobo lwedwala elakhiwe ukupholisa kanye nokukristala kwe-magma noma i-lava. Lawa madwala ahlukaniswe ngezigaba ezimbili eziyinhloko ngokusekelwe lapho aphola khona: amadwala angena ngengozi kanye namadwala angena ngengozi angaphandle. Womabili anezici ezihlukile, izinqubo zokwakheka, kanye nokubonakala. Lesi sihloko sizohlola umehluko phakathi… Funda kabanzi
Indlela Yokunquma Ubudala Bezinto Zasendulo Ukusebenzisa I-Radiometry Ukunquma ubudala bezinto zasendulo kuyisici esiyisisekelo se-paleontology kanye ne-geology. Ngaphandle kwekhono lokuthola usuku olunembile lwezinto zasendulo, isithombe sethu sokuvela kokuphila eMhlabeni besizohlala singabonakali. Enye yezindlela ezithembeke kakhulu nezisetshenziswa kabanzi zokunquma ubudala bezinto zasendulo yi-radiometry. I-Radiometry iyindlela yokulinganisa... Funda kabanzi
Ukuhlukaniswa Kwamaminerali Ngokusekelwe Ekwakhekeni Kwamakhemikhali Amaminerali ayizingxenye ezibalulekile zoqweqwe loMhlaba, aqukethe izakhiwo zekristalu ezenzeka ngokwemvelo. Ahlelwe ngokususelwa ekwakhekeni kwawo kwamakhemikhali kanye nesakhiwo sekristalu. Kulesi sihloko, sizohlola ukuhlukaniswa kwamaminerali ngokususelwa ekwakhekeni kwawo kwamakhemikhali. 1. Ama-Silicate Ama-Silicate ayiqembu lamaminerali elikhulu nelibaluleke kakhulu, akha cishe u-90% woqweqwe loMhlaba. Funda kabanzi
Umlando Wokuziphendukela Kwemvelo Womkhathi Womhlaba Umkhathi womhlaba awuyona into engashintshi. Ushintshe kakhulu kusukela kwadalwa iplanethi eminyakeni ecishe ibe yizigidigidi ezingu-4,5 edlule. Isigaba ngasinye ekuziphendukeleni kwemvelo koMhlaba sithonywe yizici ezahlukahlukene, okuhlanganisa umsebenzi wezintaba-mlilo, izinqubo ze-geological, kanye nokuvela nokuguquka kokuphila kule planethi. Lesi sihloko sihlose uku… Funda kabanzi
Izindawo Ezingaphansi Kwezingqimba Nencazelo Yazo Isingeniso Izindawo ezingaphansi kwezingqimba ziyizinto ezibalulekile ze-geological ezidlala indima ebalulekile ekushintsheni koMhlaba. Ziyizindawo lapho amapuleti amabili e-tectonic ehlangana khona, kanti elinye ipuleti lishona ngaphansi kwelinye libheke esiqongweni soMhlaba. Le nqubo ayibalulekile nje kuphela ekwakhekeni kwezintaba-mlilo, kodwa futhi nasekuchazeni ukuzamazama komhlaba... Funda kabanzi
