Izinhlobo Zokuguqulwa Kwamadwala
Ukuguquka kwedwala ukushintsha kwesimo, isikhundla, kanye/noma umthamo wamadwala ngenxa yokucindezela kanye nokushisa. Le nqubo idlala indima ebalulekile ekwakhekeni kwezakhiwo zoMhlaba kanye nezenzakalo ze-geological, njengezintaba, amaphutha, kanye nokugoba. Kulesi sihloko, sizoxoxa ngezinhlobo ezahlukene zokuguquka kwedwala kanye nezici eziwathonyayo.
Izinto Ezibangela Ukuguquka Kwedwala
Ngaphambi kokuxoxa ngezinhlobo zokuguquka kwedwala, kubalulekile ukuqonda izici ezibangela ukuba amadwala aguquke. Lezi zici zifaka:
1. Ukucindezela Kwe-Tectonic: Ukucindezela okuvundlile nokuqondile okubangelwa ukunyakaza kwamapuleti e-tectonic kungabangela ukuguquka kwedwala. Lokhu kucindezela kungabangela ukuthi idwala libhekane nokucindezelwa, ukucindezeleka, noma ukucheba.
2. Izinga Lokushisa: Izinga lokushisa eliphezulu oqweqweni lomhlaba lingenza amatshe abe yipulasitiki futhi athambekele ekuguqukeni.
3. Okuqukethwe Amanzi: Ukuba khona kwamanzi emadwaleni kungathinta amandla nokuguquguquka kwamadwala, okwenza abe sengozini yokuguqulwa.
4. Isikhathi: Ukuguquka kungenzeka ngokushesha ngenxa yokuzamazama komhlaba noma kancane kancane eminyakeni eyizigidi ngenxa yezinqubo eziqhubekayo ze-tectonic.
Izinhlobo Zokuguqulwa Kwamadwala
Ukuguqulwa kwedwala kungahlukaniswa ngezinhlobo ezahlukene ngokusekelwe ezicini nasezinqubweni ezenzekayo. Nazi ezinye izinhlobo zokuguqulwa kwedwala:
1. Ukuguqulwa Kokunwebeka
Ukuguquguquka kwe-elastic ukuguqulwa kwesimo sesikhashana kwamatshe lapho kusetshenziswa ukucindezeleka noma ukucindezeleka. Idwala lizobuyela esimweni salo sokuqala ngemva kokususwa kokucindezeleka, okufana nokuziphatha kwesiphethu. Ukuguquguquka kwe-elastic kuvame kakhulu emadwaleni atholakala ebusweni boMhlaba noma ekujuleni okungajulile. Ukuqina kwedwala kuncike ohlotsheni lweminerali, isakhiwo salo sekristalu, kanye nezimo zemvelo lapho litholakala khona.
2. Ukuguqulwa Kwepulasitiki (i-Ductal)
Ukuguquka kwepulasitiki noma kwepayipi kungukushintsha okuhlala njalo kwesimo okwenzeka lapho idwala licindezelwa ngokwanele ukuze lifinyelele umkhawulo walo wokunwebeka futhi liqale ukuzwa ukugeleza kwepulasitiki. Idwala eliguqulwa yipulasitiki alibuyeli esimweni salo sokuqala lapho ukucindezeleka kususwa.
Ukuguquka kwepulasitiki kuvame kakhulu emadwaleni ekujuleni okukhulu, lapho amazinga okushisa aphezulu kanye nokucindezela kwenza amatshe abe yipulasitiki kakhulu. Isibonelo esivamile sokuguquka kwepulasitiki ukugoqeka kwamatshe okwenzeka ezindaweni ezinezintaba ngenxa yokucindezelwa kwe-tectonic.
3. Ukuguqulwa Okuncane
Ukuguquguquka kwesimo okubhidlikayo kuwukushintsha kwesimo okwenzeka lapho amatshe ebhekene nokucindezeleka okungaphezu kwamandla awo, okubangela imifantu noma ukuqhekeka. Lokhu kuguquguquka kuvame ukwenzeka emadwaleni aseduze nobuso boMhlaba, lapho amazinga okushisa ephansi khona futhi amadwala ebhidlika kakhulu.
Ukuqhekeka noma ukuqhekeka okubangelwa ukuguquguquka okuqhekeka kungasukela kokuncane kuya kokukhulu. Kunezinhlobo ezimbili eziyinhloko zamaphutha: amaphutha ajwayelekile, ayenzeka lapho amatshe edonswa phakathi ngokucindezeleka kokwelulwa, kanye namaphutha abuyela emuva, ayenzeka lapho amatshe esunduzwa ndawonye ngokucindezeleka kokucindezela.
4. Ukuguquka Okugelezayo
Ukuguquka kokugeleza kwenzeka lapho amatshe eshintsha kancane kancane isimo ngenxa yokucindezeleka kwesikhathi eside. Lesi simo sivame ukwenzeka emadwaleni ase-sedimentary kanye nobumba, obubonisa izakhiwo zepulasitiki ngaphansi kwezimo ezithile. Ukuguquka kokugeleza kungabangela ukwakheka kwezakhiwo ze-geological ezifana ne-synclines kanye ne-antiticlines.
5. Ukuguqulwa kwe-Thermoelastic
Ukuguquguquka kwe-Thermoelastic ukushintsha kwesimo sedwala okwenzeka ngenxa yokushintsha kwezinga lokushisa. Ukwanda kwezinga lokushisa kubangela ukuba amatshe ande, kuyilapho ukwehla kwezinga lokushisa kubangela ukuthi anciphe. Ukuguquguquka kwe-Thermoelastic kuvame ukuguquka, okusho ukuthi idwala lizobuyela esimweni salo sokuqala uma izinga lokushisa libuyela esimweni salo sokuqala. Lokhu kuvame ukubonakala emadwaleni asebusweni boMhlaba abhekana nemijikelezo yansuku zonke noma yesizini yokushisa nokupholisa.
6. Ukuguqulwa Kwesimo Sezwe
Ukuguquguquka kwesimo sezulu kwenzeka ngenxa yokuzamazama komhlaba. Lapho kwenzeka ukuzamazama komhlaba, amagagasi okuzamazama komhlaba akhishwa ukunyakaza kwamaphutha angabangela ukuguquguquka kwedwala okusheshayo. Ukuguquguquka kwesimo sezulu kungahlanganisa izinto zokuguquguquka okunwebekayo, kwepulasitiki, kanye nokuqhekeka, kuye ngokuthi ukuzamazama komhlaba kunamandla kangakanani kanye nezakhiwo zomzimba zedwala.
Izinqubo Zokwakheka Kokuguquka
Akukhona nje kuphela ukuthi izinhlobo zokuguquka kwesimo zibalulekile, kodwa futhi nezinqubo eziholela ekwakhekeni kokuguquka kwesimo se ...
1. Ukugoqa
Ukugoqa kuyinqubo yokuguquka kwedwala eyenzeka lapho ungqimba lwedwala olwaluyisicaba lucindezelwa, lwakha isakhiwo esinamagagasi. Kunezinhlobo ezimbili eziyinhloko zokugoqa:
– Ukugoba Okuphambene: Isakhiwo sokugoba esakha isiqongo noma umqolo.
– Ukugoqa kwe-Syncline: Isakhiwo sokugoqa esakha isigodi noma isisu.
Ukugoba kuvame ukwenzeka ezindaweni zokuhlangana kwamapuleti e-tectonic, lapho amapuleti amabili eshayisana khona futhi abangele ukucindezelwa kwedwala.
2. Ukwehluleka
Iphutha inqubo yokuguquguquka ehilela ukunyakaza okuhlobene kwamabhlogo amatshe emifantwini noma emaqhekekeni. Amaphutha ahlukaniswe ngezinhlobo eziningana ngokusekelwe ohlotsheni lokunyakaza:
– Iphutha Elijwayelekile: Amabhlogo edwala aya phansi uma kuqhathaniswa namanye amabhlogo.
– Iphutha Elibuyela Emuva: Ibhloko ledwala liya phezulu uma liqhathaniswa nelinye ibhloko.
– Iphutha Elivundlile: Ukunyakaza okuvundlile phakathi kwamabhulokhi edwala.
Amaphutha angenzeka ezindaweni ezahlukahlukene ze-tectonic, okuhlanganisa ukuhlukana, ukuhlangana, kanye nezindawo zokuguqula.
3. Ukuhlukana kanye nokuboshwa kwe-Gneiss
Ukuqhekeka kanye nokuboshwa kwe-gneiss kuyizakhiwo ezenzeka emadwaleni ashintshayo ngenxa yokuguqulwa kanye nokuvuselelwa kwamaminerali. Ukuqhekeka kuwukuqhekeka okuncane, okufanayo emadwaleni ashintshayo njenge-schist, kuyilapho ukuboshwa kwe-gneiss kuwukwakheka kwamabhande ahlukene amaminerali ngaphakathi kwe-gneiss.
4. Izindawo Zokugunda
Izindawo zokugunda amatshe yizindawo ezibhekana nokushintshashintsha okukhulu ngenxa yokuguquguquka kokungqubuzana, noma ukugunda amatshe. Lezi zindawo zivame ukubonisa ukuguquguquka okukhulu kanye nokugundwa kwamatshe.
Isiphetho
Ukuguquka kwedwala kuyinto eyinkimbinkimbi ethonywa yizici ezahlukahlukene ezifana nokucindezela, izinga lokushisa, okuqukethwe amanzi, nesikhathi. Ngokuqonda izinhlobo ezahlukene zokuguquka kwedwala—okunwebekayo, okupulasitiki, okuqhekeka kalula, okugelezayo, okuguquguqukayo, kanye nokuzamazama komhlaba—kanye nezinqubo ezibangela ukuguquka, njengokugoqeka kanye nokuqhekeka, singathola ukuqonda okungcono kwamandla oMhlaba kanye nethonya lawo ezimeni zomhlaba kanye nezakhiwo ze-geological.
Lolu lwazi alubalulekile nje kuphela kososayensi bezinto zomhlaba kanye nososayensi bezimayini, kodwa nakubahleli bengqalasizinda kanye nomphakathi ojwayelekile ohlala ezindaweni ezisengozini yezingozi zezinto zomhlaba. Ngokuqhubeka nokufunda ngokuguqulwa kwamadwala, singathuthukisa imizamo yokunciphisa ubungozi futhi sithole ukuqonda okujulile ngokuvela koMhlaba wethu.
