Iplanethi yomhlaba iguqulwa ngokuqhubekayo ngokuhamba kwesikhathi. Kunochungechunge lwezinqubo zangaphandle ezenza iplanethi yethu iguquke ngokuqhubekayo. Yilokhu ababizwa ngakho ama-geological agents angaphandle. Yilawo ma-ejenti akwazi ukuguqula ukwakheka kwangaphandle kweplanethi yethu futhi ayiguqule ngokuqhubekayo ngokuhamba kwesikhathi.
Kulesi sihloko sizokutshela ngazo zonke izici nezinhlobo zama-geological agents angaphandle.
Yini ama-geological agents angaphandle
Ngokungafani nemisebenzi yangaphakathi kwiplanethi yethu, ama-geological agents angadali ukwehla, izintaba noma izintaba-mlilo. Yilawo ma-ejenti akhulula umhlaba futhi aguqule kancane kancane amafomu azotholwa yi-landscape.
Izakhi zokwakheka komhlaba ezinkulu eziyinhloko ukuguguleka komhlaba, ezokuthutha kanye nentlenga. Lawa ma-geological agents avela ngokuqhubekayo ngokuhamba kwesikhathi. Eqinisweni, zingenzeka ngasikhathi sinye ngenkathi ziguqula indawo esiyibonayo. Lawa ma-ejenti we-geological angaphandle azoba ikakhulukazi ezindaweni zemvelo. Emadolobheni nasezindaweni ezisemadolobheni kunzima kakhulu ukulinganisa lezi zinqubo ngokuhamba kwesikhathi ngoba abantu bahlala beguqula imvelo.
Olunye uhlobo lwento eguqukayo yokwakheka kwezulu isimo sezulu. I-ejenti yangaphandle ebaluleke kakhulu ngoba ihlanganisa zonke lezo zinto ezenzeka emkhathini nasemazingeni aphansi nezithinta indawo.
Uhlobo umhlaba oluthola ngenqubo yokwakheka komhlaba luhlukahlukene futhi luhlukahlukene. Ukukhululeka kokwakheka kwentaba kungaguqulwa ngokuqhubekayo ngokuhamba kwesikhathi kanye nokwenziwa kwalezi zinqubo. Esinye sezibonelo ezicace bha ezingabonakala ngamehlo enyama nokuthi iminyaka yentaba ingalinganiselwa ngayo ukuguguleka komhlaba. Uma sibheka intaba ebesineminyaka eyizigidi nezigidi zeminyaka selokhu yakhiwa, siyabona ukuthi isenzo esiqhubekayo sokuguguleka sigudlise zonke iziqongo zentaba. Ngakho-ke, Enye indlela yokulinganisela cishe iminyaka yentaba ukubona ubude nokuma kweziqongo.
Uma intaba inesimo esicijile, incane futhi uma ngabe yayivele ikhona, kungenxa yokuthi ukuguguleka komhlaba kuqhubekile nokusebenza izigidi zeminyaka.
Izinhlobo zama-geological agents angaphandle
Kunezinhlobo ezahlukahlukene zama-geological agents angaphandle futhi angaba womzimba kanye namakhemikhali. Abokuqala yibo abanesibopho sokushintsha umumo kanti owokugcina yilabo ababhekene nokuguqula ukwakheka kwamakhemikhali esakhiweni salezo zindawo abasebenza kuzo. Esinye sezibonelo ezicace bha zamakhemikhali angaphandle womumo wamakhemikhali sezulu.
Ububanzi bomhlaba bungabonakala njengomphumela wokuxhumana kwazo zonke lezi zinqubo zokwakheka komhlaba ezenzeka ngasikhathi sinye kanye nesenzo izidalwa eziphilayo ezifana nezimbali, izilwane nezilwane umuntu anaso ngaphambi kwalesi simiso semvelo. Isimo sendawo singahlanganiswa nokwenziwa kwezinto eziningi eziphilayo futhi, yize zikhula ngokuqhubekayo, zingaba nomthelela emvelweni. Isidalwa esingumuntu singesinye sezici zokulungisa isimo ekuguqulweni kokwehlukahlukana kumathafa wanamuhla.
Isimo sezulu
Isimo sezulu somzimba
Isimo sezulu esibonakalayo yileso sakhiwo esikwazi ukuphula noma ukuguqula amadwala ngokuya ngesenzo saso kanye nezimo zemvelo esizithola sikuso. Lesi simo sezulu siphunyuka ekuqhekekeni kwetshe futhi sisebenze ngqo kumaminerali alibumbayo. Izimbangela zalesi simo sezulu sezulu: imvula, iqhwa, ukuncibilika, umoya kanye nezinguquko eziqhubekayo ezenzeka ekushiseni phakathi kwemini nobusuku. Ukuphakama kobubanzi bamazinga okushisa emini nasebusuku, kukhula kakhulu isimo sezulu ngokomzimba ngalesi sizathu.
Isimo sezulu somzimba ngenxa yomphumela wokushisa kubizwa ngokuthi yi-thermoclasty. Eminyakeni edlule, lokhu kwehlukahlukana emazingeni okushisa aqhubekayo kubangela ukuthi izinto zibhidlike. Kwenzeka kaningi ezindaweni ezinomswakama ophansi nokwehluka okukhulu kwamazinga okushisa. Kukhona futhi isimo sezulu se-biogenic. Yikho okubangela isenzo sezidalwa ezinjengobulembu, ubulembu, ulwelwe nezinye izimbaza ezithinta ubuso bamadwala.
Isimo sezulu sezulu
Kuyisenzo izinqubo ezahlukahlukene zokwakheka komhlaba esinazo ekwakheni amakhemikhali amatshe. Lesi simo sezulu senzeka ikakhulukazi ezindaweni ezinezimo ezinomswakama lapho kwenzeka khona amakhemikhali phakathi komkhathi namaminerali akhona edwaleni. Amanzi nokuba khona kwamagesi afana ne-oxygen ne-hydrogen kuba yizimbangela zokuphendula kwamakhemikhali okukhiqiza lesi simo sezulu.. Okunye ukusabela okuyinhloko ukuthi lolu hlobo lwesimo sezulu lwenzeka yi-oxidation. Lesi simo senzeka ngenxa yenhlanganisela yomoya-mpilo okhona emoyeni oncibilikisiwe namanzi amaminerali edwaleni.
Ukuguguleka kwenhlabathi, ukuthuthwa kanye nenzika
Amanye ama-geological agents angaphandle akwazi ukuguqula indawo. Yileso esenzeka lapho imvula, umoya noma amanye amanzi egeleza esebenza emadwaleni nasenzunjini. Lesi senzo saqhubeka sibangela ukuhlukana nokuqhekeka kwamatshe. Njengoba amadwala eguguleka, alahlekelwa ivolumu futhi ukubukeka kwawo konke kukhubazekile.
Ezokuthutha yinqubo etholakala ngokuguguleka. Izinsalela ezihlukanisiwe futhi ezincane ngenxa yesenzo sokuguguleka zihanjiswa ngumoya, izikhukhula zamanzi, izinguzunga zeqhwa, njll.
Ekugcineni, ukudilika kwenhlabathi inqubo lapho izinhlayiya eziqinile ezihanjiswe ukuguguleka zigcina zibekwe endaweni. Lezi zinhlayiya zibizwa ngokuthi izidalwa. Izindawo ezinenhlabathi eningi kakhulu kunemilambo yemifula nasezindaweni ezinjengezilwandle nezilwandle. Lezi zinsalela zingaguqulwa futhi ngama-ejenti we-geological wangaphandle ahlukahlukene njengokuguguleka kanye nesimo sezulu.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nama-geological agents ahlukile angaphandle.
