I-Cryoclastism

Indawo yokusabela yeentaba eziphakamileyo ejikelezwe ziicones ezidityanisiweyo zobutyobo bamanzi aphantsi komhlaba, eziveliswe ubukhulu becala kukuqokelelwa kwamaqhekeza amatye asuka kuqhekeko lwe-cryoclastic yeendonga zamatye eziphantsi.

I-Cryoclastism yinkqubo yokuchithwa komatshini welitye elibangelwa kuxinzelelo olubangelwa ukwanda komthamo wamanzi aqulethwe ngaphakathi kweentanda zamatye xa iqhekeza ilitye. ngumkhenkce.

Ngomjikelo wemozulu engumkhenkce, ilitye, elalifudula libumbene, liyaqhekeka libe bubutyobo begrabile nemiphetho ebukhali; le nkqubo iqhelekile kwiindawo apho kukho ukuguquguquka kobushushu obujikeleze i-0. °C ethe gqolo ukuphembelela utshintsho kwisimo somzimba samanzi akhoyo.

I-Cryoclastism iphula amatye abe ngamaqhekeza, kodwa ayiwatshintshi kwimbono yeekhemikhali, kuba iziqwenga, nokuba zinkulu okanye zincinci, zenziwe ngamaminerali afanayo abumba "ilitye lomzali" apho bahlukana khona. Amaqhekeza aqhawukileyo, ahlala enencam ezibukhali, anokuhlala esendaweni, ngaphandle kwayo nayiphi na intshukumo, ukuba isenzeko senzeka kwindawo ethe tyaba yamatye, okanye ukuba isenzeko se-detachment senzeka phezu kobuso bamatye, nokuba bubude obuncinci, ukuwa ukusuka eludongeni lwamatye kwaye emva koko uqengqele ngasentlanjeni kwaye ube negalelo ekwenzeni into ebizwa ngokuba yimfucumfucu yamanzi aphantsi komhlaba, eyenziwe ngeecones zenkunkuma, idibanisa kunye, umoya ophantsi kweendonga zamatye kunye nokuhambelana nokuhamba kwawo, kunye ne-slope ye-cone ehambelana ne-cone. ixabiso le engile yokukhuhla yangaphakathi yezinto eziqhekeziweyo.

Ilitye e- Abisko mhlawumbi laphukile (kunye namalungu asele ekhona) yi-cryoclastism yomatshini okanye utshintsho lobushushu.

I-Cryoclastism ibhekiselele kwiinkqubo ezininzi zokhukuliseko lomatshini olubangelwa luxinzelelo oludalwe kukupholisa kwamanzi aguqulwe abe ngumkhenkce, njengokuqhekeka kunye nokuqhekeka komkhenkce, i-cryofracturing. I-Cryoclastism inokusebenza ngokwesikali sexesha elide, ukusuka kwimizuzu ukuya kwiminyaka, kunye nokugxothwa kweegranule zezimbiwa kunye nokuqhekeka kwamatye kwaye iqhutywa ikakhulu kukuphindaphinda kunye nobunzulu bemijikelo yokunyibilika komkhenkce kunye neempawu zemathiriyeli ephantsi. ukhukuliseko. Ukuchazwa ngakumbi kwimimandla yokuphakama okuphezulu kunye nobubanzi, ngokuqhelekileyo kuhambelana ne-alpine, i-periglacial, i-subpolar maritime, kunye nemozulu epholileyo, kodwa kwenzeka naphi na apho kukho imijikelo ye-freeze-thaw.
