Yini weathering? izinhlobo weathering

Enye yezinkinga ezivamile ekugcinweni umhlaba wokulima kuyinto ukuguguleka kwenhlabathi. It kwenzeka ezindaweni ezomile ezweni elivulekile. Ngokuvamile, lokhu kuphumela weathering yemvelo, okuyinto bayehluleka ngezindlela eziningi, njengoba umthetho, esekelwe ukulawulwa imingcele wokubacindezela cover umhlaba. Kodwa kukhona ukuqonda ebanzi we weathering ukuthi asithinti nje kuphela inhlabathi kodwa rock futhi. Kulokhu kuyafaneleka ukukhulisa umbuzo uyini weathering amaminerali? Lokhu kubuye inqubo yemvelo yokubhubha, Nokho, okuyinto, kungase kuphakame hhayi kuphela ngenxa aridity kakhulu.

ulwazi olujwayelekile mayelana weathering

Yikambiso ngaphansi weathering umthelela yangaphandle phezu kwedwala lapho ukubhujiswa noma yokubola isisekelo Ngaphandle kwezinto zalo ezibonakalayo. Ingabe Zikhona Izimo Ezenza okubangela izenzakalo ezinjalo zingase zibe uhlamvu ezahlukene - ukusuka amanzi ukuze asemkhathini chemical ukusabela. Ezimweni eziningi, amaminerali izenzo sebuningini izinto ezahlukene, ekugcineni okuholela Ukuwohloka edwaleni. Futhi umbuzo ngokuqondene nalokho okushiwo weathering, asikwazi ancike ukuqonda zasendulo imisebenzi ngokuqondile umoya noma ezinye izici exogenous. Ngisho evamile yezinqubo zamakhemikhali ngokomzimba azibonisi ngokugcwele ukuphelela lesi simanga. Ngokwesibonelo, lapho kubhujiswa bayakwazi ukubamba iqhaza nemisebenzi ukuphendula igesi. Ikakhulukazi, isikhutha nomoya-mpilo ukunikeza umphumela asebenzayo kwamakhemikhali. Enye into ukuthi kungenzeka preconditions ngabo ixhunyaniswe zibangelwa yizenzo zabantu - isibonelo, ngaphansi kwencazelo yoMthetho kwezolimo efanayo.

izinhlobo weathering

Ngokuvamile secrete zamakhemikhali weathering ngokomzimba izinqubo, avamise esihlobene futhi umphelelisi nomunye. Ingabe umfutho wabo ingase yehluke kuye ngesistimu zezemvelo. Kodwa futhi kwezinye izindawo izinqubo of izakhi futhi njalo yokuchayeka emisebeni ye zivamile. Ngaphezu kwalokho, ngokunembile izenzakalo ezinjalo zivame buphawuleka kakhulu ekubhujisweni. Chemical futhi izinqubo zemvelo nazo lemvelo kanye kungashiwo ukwenzeka njalo, kodwa degrees ithonya ehlukahlukene isakhiwo ngezinto zemvelo. Biogenic weathering izinhlobo nakho kungase kube umphumela okukhulu kakade chemical yokubola.

Umsebenzi esiyinikwe isici weathering akuxhomekile nje kuphela esimweni emathonyeni zangaphandle kodwa futhi izici edwaleni. Ngokuvamile, ochwepheshe cabanga isiqalo nesigcino imihlola. Ngakho, njengoba izici eziyinhloko ukuthi ukunquma kwalokho noma ezinye izinqubo weathering, isimo sezulu elingalodwa, izici nesimo sendawo, izici zomhlaba, ukwakheka kanye nesakhiwo edwaleni.

Inqubo weathering

Phakathi kwezimbangela eziyinhloko lolu hlobo ochwepheshe weathering ushayele abukhali futhi njalo lokushisa izinguquko. Uma emini amaminerali ebusweni heats futhi eyandisa, ebusuku kulandela ukutholana inqubo ukupholisa siyachithwa isakhiwo entengo. Ngenxa yalokho, kwemifantu kwenzeka angawethusi rocks ku izinhlayiya ezincane. Lolu hlobo ukusonteka, okuyinto, futhi, kungokwaphakade, nakuba avulekile. Ikakhulukazi liphinyiselwe weathering ngokomzimba izindawo ezibandayo, lapho ngokuvamile kukhona yesithwathwa e. Iqiniso lokuthi isakhiwo amaminerali ukunamathela umswakama ngezikhathi ezinjalo osemanzi futhi crystallizes, okwandisa ukungezwani futhi ngokwemvelo kuholela kwemifantu babubukhulu ngokwengeziwe. Nikela emsebenzini abhubhisayo futhi vibration embossed ikhava, okuvame zenzeka engazinzile ngokuya izifunda zomhlaba zedivayisi.

I weathering chemical

Phenomena walolu hlobo ingase futhi neqembu elikhulu izici okuyizinto ungakuvumeli ukuba ke imbubhiso njalo. Kuye zamakhemikhali ezithinta isakhiwo idwala lungase lubonwe futhi ukusonteka izinqubo kanye kumiswa namaminerali entsha. Kuzo zombili lezi zimo kuyoba ushintsho qualitative lichaza ekwakheni begodu nesakhiwo into. Esikhathini izici ngokushesha lapho kusebenze chemical weathering, zikhipha amanzi, umoya-mpilo ne-carbon dioxide. Ngokwesibonelo, imithombo yamanzi ngokwemvelo umusa ezinye uhlobo rock kuphela. Amandla ukuxhumana yamanzi nokumbiwa incike Ukwakheka amakhemikhali uketshezi. Ngesikhathi esifanayo, futhi ukusabela ngokwayo ingase ibe khona ehlukile. Ngakho, igneous idwala amaminerali amanzi kuthinta ukusabela nge hydrolysis. yi wayo ungaba indawo izakhi alikhali ngoba hydrogen ion.

weathering Biogenic noma organic

Njengoba sekuphawuliwe kakade, umthelela engengaphansi phezu namaminerali anganikeza futhi izici zokwakheka komuntu. Lezi zihlanganisa umsebenzi izitshalo, sidla amagundane amancane nesikhunta microbial ikakhulukazi nama-bacterium. Zizonke, lezi zici kungase kusinikeze isilinganiso esithile ukuphazamiseka kwenqubo sokukhaphela sasisibi ngaphezu le izici ezingokomzimba noma amakhemikhali. Kodwa futhi incike izimo ezithile endaweni lapho kukhona khona idwala. Kuyini ubunjalo weathering biogenic emsebenzini? Kungenzeka, isibonelo, umsebenzi eziphilayo, nokuqeda ungqimba amaminerali inhlabathi. Ngakho usebenza ohlelweni impande izihlahla. Ezinye izinhlobo ze-moss ingaba njengesihluthulelo umthombo chemical yokusabela ukukhulula acid, kamuva is ukubola ngabanye izingxenye izimayini nhlanganisela.

Izici weathering emisebeni

Omunye eziyingozi kakhulu yinqubo njalo yokuchayeka emisebeni ye. It libhekene umfutho high kanye nesikhathi, futhi ayeke kungenzeki ezimweni eziningi. Kodwa nakhu ukunikeza kwelanga yemvelo, okuyinto yeqembu yezici ngemisebe futhi izinqubo technogenic. Endabeni yesibili, weathering yamadwala iyona zibangelwa yizenzo zabantu. Isibonelo yakudala umsebenzi ngemapholigoni okuyinto ukugcina imfucuza toxicologically enobungozi. Ngenxa yalokho, afanayo elilandelayo ngamatshe izoba ngaphansi imiphumela elimazayo, futhi esebenzayo isici yokubola.

Yini weathering uqweqwe

Sizokwenza baqonde futhi le ndaba. izinqubo weathering singenzeka ngokuqhubekayo noma nezikhathi. Kodwa ezimweni zombili, ebusweni lapho kukhona izinto ezithile qualitative ka ukusonteka, eqala ukubukeka. Lokhu kuyoba uqweqwe weathering, izimpawu Looseness kanye mafutha amakhemikhali ukwakheka.

Ngokuvamile, izingqimba engenhla izingqimba ezinjalo ngaphansi ukubola kanye ohlukaniswa khona yezingxenye metal. Kungaba, isibonelo, hydroxides ka-silicon noma aluminium. Izoni elandelayo lapho hydroxides yensimbi abakhona, ukwakheka okuyinto wathonywa chemical weathering ngamandla kancane. Ezingqimbeni engezansi cortex ngokuvamile amanga limestone kanye Gypsum concretions.

imikhiqizo weathering

Ngokuvamile phakathi weathering izingcezwana itshe ahlale, izinhlayiya isihlabathi, imvuthu yamatshe, ubumba kanye kaolin izingxenyana zaso. Uma lokhu inqanyuliwe izakhi idwala angase abe emasayizi nabobunjwa labehlukene - incike izimo ezithile kanye izinto weathering. Kwezinye izimo kungenzeka kanye kumiswa Kuruma. Lokhu izigaxa omkhulu ukuze kuvuleke svezheoblomannyh kwakhiwa kusukela amafraktjhini oshiwo ngenhla. osayizi Standard isukela Kurume 1 2 amamitha, nakuba zikhona izenzakalo hamba okuningi okudlula lokho. Ngokuvamile, ukwakheka amabhlogo enjalo inikeza weathering ngokomzimba, okungase kuholele ekungasebenzini ukudalwa itshe futhi igobolondo nge kurumovym flooring.

isiphetho

Weathering kwenzeka nje kuphela ntshashintshe okujula, kodwa futhi etigabeni letehlukene kokusebenza. Isibonelo elula kungaba inqubo ngokomzimba nolokubhujiswa ngenxa lokushisa imiphumela. Ngaphezu kwalokho, kungaba ixhunywe futhi ukusabela chemical khona uketshezi oluxube asebenzayo beyobe behileleke khona. Manje kubalulekile ukuze ujike yombuzo kuyini ubunjalo weathering organic. Ngokwengxenye le nqubo biodegradation, okungase ngokwemvelo kungaholela ekwakhekeni entsha namadwala. Ngakho, weathering ayikwazi kubhekwe kuphela njengoba ukubhujiswa amaminerali ekhona. Ngisho noma ukusonteka usuphothuliwe at the stage of ngokuhlukana obungokomzimba ngenxa yokuhlushwa njalo kuyizinhlayiyana okuqinile, lolu shintsho zingaba nomthelela ekwakhekeni namaminerali entsha noma conglomerates ukuthi uqinisekise ukhona kurums.
