Kodi weathering? mitundu ya weathering

Limodzi mwa mavuto ambiri mu ntchito yokonza zaulimi ndi kukokoloka kwa nthaka. Kumachitika m'madera youma dziko lotseguka. Nthawi zambiri zimenezi zimachititsa weathering zachilengedwe, zomwe akuvutika m'njira zambiri, monga ulamuliro, potengera lamulo la magawo hayidiroliki a chivundikirocho dziko. Koma pali luntha timapangira wa weathering kuti zimakhudza nthaka komanso thanthwe. Pankhaniyi n'koyenera kuukitsa funso kodi weathering mchere? Iyi ndi ndondomeko chilengedwe cha chiwonongeko, amene Komabe, angakhalepo osati chifukwa cha aridity kwambiri.

General zokhudza weathering ndi

Amatanthauza ndondomeko pansi weathering amadza kunja pa thanthwe limene chiwonongeko kapena kuwonongeka kwa maziko ake zakuthupi. Zinthu kuchititsa zochitika zingakukhudzireni khalidwe osiyana - kuchokera madzi zosiyanasiyana mankhwala mlengalenga. Nthawi zambiri, mchere amachita kuchuluka kwa zinthu zosiyana, kenako zikubweretsa zikutha m'mayiko thanthwe. Ndipo pa funso la zimene weathering, sitingathe kudalira kumvetsa chakale cha ntchito mwachindunji mphepo kapena zina zinthu exogenous. Ngakhale alipidwa mankhwala ndi thupi njira sazindikira mokwanira kusonyeza chidzalo cha zodabwitsazi. Mwachitsanzo, chiwonongeko akhoza kutengapo mbali ndi zochitika anachita mpweya. Makamaka, mpweya woipa ndi mpweya kupereka yogwira amuzolengedwa kwenikweni. Chinthu china ndi chakuti preconditions kwa iwo akhoza zogwirizana ndi chifukwa cha zochita za anthu - mwachitsanzo, mwa tanthauzo la ulimi chomwecho.

mitundu ya weathering

Bwinobwino secrete mankhwala ndi weathering thupi njira, amene kaŵirikaŵiri zogwirizana ndipo azigwirizana. Kodi mwamphamvu awo zingasiyane malingana ndi mmene chilengedwe. Komanso m'madera ena a njira ya michere ndi cheza kukhudzana ndi ofanana. Komanso, ndendende zochitika amenewa nthawi zambiri kutchulidwa chiwonongeko. Mankhwala ndi njira thupi amatha zachilengedwe ndi tinganene kuti zimachitika nthawi zonse, koma ndi amawasonyeza mosiyanasiyana wa chikoka pa kapangidwe ka zipangizo achilengedwe. Mitundu Biogenic weathering angakhalenso zotsatira za kale kwambiri mankhwala kuwonongeka.

Ntchito ya anapatsidwa chinthu weathering kumadalira osati kokha asatengere kunja komanso maonekedwe a pathanthwe. Nthawi zambiri, akatswiri kuganizira kuchotsedwa zochitika. Choncho, ngati zinthu zofunika kwambiri kudziwa izi kapena njira zina weathering kutali nyengo mbali zimachititsa chilumbachi, makhalidwe tectonic, zikuchokera ndi dongosolo la thanthwe.

ndondomeko weathering

Mwa mavuto akuluakulu amene amayambitsa mtundu uwu weathering akatswiri kuitana lakuthwa ndi zonse kusintha kutentha. Ngati mchere masana pamwamba heats ndi zambiri, usiku pakati ndondomeko yozizira Zinasintha kuchepetsedwa dongosolo. Chifukwa, akulimbana amapezeka ndi kupsinja miyala mu particles ang'onoang'ono. Mtundu uwu wa mapindikidwe, amene kachiwiri, ndi wachikhalire, ngakhale unobtrusive. Makamaka kutchulidwa weathering thupi m'madera ozizira, kumene nthawi zambiri pali frosts. Popeza kuti Kapangidwe ka mchere kutsatira chinyezi pa nthawi ngati solidifies ndi crystallizes, amene kumawonjezera mavuto ndi mwachibadwa akutitsogolera kuti akulimbana kwambiri. Zimathandiza kuti ntchito yotayikitsa, kugwedera embossed chivundikiro, nthawi zambiri zimachitika osalimba mawu a m'madera tectonic chipangizo.

The weathering mankhwala

Zochitika za chikhalidwe ichi amathanso kugwirizana ndi gulu lalikulu la zinthu zomwe si nthawi zonse abwino izo chiwonongeko. Malinga ndi zochita mankhwala okhudza kapangidwe thanthwe akhoza anaona ndi njira mapindikidwe ndi mapangidwe mchere latsopano. Nthawi zonse zidzakhala kusintha Mkhalidwe mu kapangidwe ndi kapangidwe ka chinthu. Mu zinthu mwamsanga zimene yambitsa mankhwala weathering, kutulutsa madzi, mpweya ndi mpweya. Mwachitsanzo, zopezeka madzi mwachibadwa mtima mtundu wa thanthwe zosungunulira. Mphamvu ya mogwirizana wa madzi ndi mchere zimadalira mipweya ya madzimadzi. Pa nthawi yomweyo, ndipo anachita kungakhale osiyana. Choncho, igneous thanthwe mchere madzi amakhudza anachita ndi hydrolysis. Zotsatira zake zikhoza kukhala m'malo a zinthu soda kwa ayoni wa hydrogen.

Biogenic kapena organic weathering

Monga tanenera kale, chimodzimodzi yaikulu mchere akhoza kupereka ndi zifukwa za chilengedwe. Zikuphatikizapo ntchito ya zomera, makoswe ang'ono ndi bowa makamaka tizilombo tating'onoting'ono ndi mabakiteriya. Pamodzi, mfundozi amapereka lalikulu kusokonezeka ndondomeko kuposa zinthu zakuthupi kapena mankhwala. Koma zimatengera zinthu zenizeni za dera lomwe lili thanthwe. ndi chikhalidwe cha weathering biogenic kuchita chiyani? Kungakhale Mwachitsanzo, ntchito ya zamoyo, kuvutitsa wosanjikiza mchere nthaka. Choncho ukugwira ntchito pa mizu ya mitengo. Ena mitundu Moss akhoza kuchita monga gwero la mankhwala anachita kumasuka asidi, amene kenako ndi linakwiriridwa munthu zigawo zikuluzikulu migodi yense.

Features cheza weathering

Mmodzi wa owopsa ndi ndondomeko cheza kukhudzana. Iwo amakhala ndi mwamphamvu yapamwamba ndi nthawi, ndi kusiya n'zosatheka nthawi zambiri. Koma pano ndi kupereka dzuwa zachilengedwe, zomwe ndi mbali ya gulu la zinthu dzuwa, ndi njira technogenic. Ngati chachiwiri, weathering wa miyala chifukwa cha zochita za anthu. Chitsanzo chachikulu tingachipeze powerenga ndi ntchito ya polygons zimene zimasunga zinyalala toxicologically woopsawo. Motero, magulu lotsatira ndi miyala ndipo gonjerani mavuto aakulu, ndi yogwira chinthu kuwonongeka.

Kodi weathering kutumphuka

Ife adzamvetsa ndi nkhaniyi. weathering njira angayambe mosalekeza kapena nthawi. Koma nthawi zonse, pamwamba pa zomwe pali zinthu Mkhalidwe wa mapindikidwe, amapeza maonekedwe khalidwe. Chimenechi chidzakhala kutumphuka weathering, amene yodziwika ndi looseness ndi Taphunzira mipweya.

Childs, zigawo chapamwamba zigawo ngati zochepa linakwiriridwa ndi wolemekezeka ndi kukhalapo kwa zigawo zikuluzikulu zitsulo. Kungakhale Mwachitsanzo, hydroxides wa pakachitsulo kapena zotayidwa. Zotsatirazi zone kumene hydroxides chitsulo alipo, mapangidwe amene ankatsatira mankhwala weathering mwamphamvu zochepa. Mu zigawo za mmusi za kotekisi kawirikawiri kugona anajambulapo ndi gypsum concretions.

mankhwala weathering

Childs pa weathering zidutswa mwala kukhala, particles mchenga, chomenyedwa, dongo ndi kaolin wa ting'onoting'ono. Pamene izi sakukhudzidwa ndi zinthu thanthwe mwina zazikulu ndi zooneka mosiyanasiyana - izo zimatengera zinthu zenizeni ndi zinthu weathering. Nthawi zina n'zotheka ndi mapangidwe Kuruma. Izi apezeka chachikulu ndi boulders svezheoblomannyh anapangidwa kuchokera tuzigawo twa tatchulawa. Milingo yabwino imathandiza mulimi osiyanasiyana monga Kurume 1 mamita 2, ngakhale pali nthawi kuti tipite kupyola zimenezo. Nthawi zambiri, mapangidwe midadada amenewa amapereka weathering thupi, kumene zingadzetse chilengedwe cha mwala ndi chipolopolo ndi kurumovym yazokonza pansi.

Pomaliza

Weathering amapezeka osati ndi osiyana mwamphamvu, komanso kosiyana kukhazikitsa. Chitsanzo losavuta adzakhala ndondomeko thupi chiwonongeko chifukwa zotsatira kutentha. Komanso akhoza chokhudzana ndi mankhwala anachita zimene madzi ndi zinthu yogwira adzaloŵetsedwamo. Tsopano m'pofunika titembenukira kwa funso la chimene chiri chikhalidwe cha weathering organic. Mwina ichi ndondomeko biodegradation, amene angathe mwachibadwa kuyambitsa mapangidwe latsopano ndi miyala. Choncho, weathering sangatengedwe kukhala okha monga chiwonongeko cha mchere alipo. Ngakhale mapindikidwe amaliza pa siteji ya kupatukana thupi la tinthu olimba, kusintha zimachititsa mapangidwe mchere latsopano kapena conglomerates kuti atsimikizire linakhalapo kurums.
