Chii chiri weathering? mhando weathering

Chimwe chezvinhu zvinozivikanwa munyika kwerunyararo yekurima iri kukurwa kwevhu. It kunoitika rakaoma nzvimbo mumaruwa. Kakawanda, izvi zvinoguma dzinongoitika weathering, dziri kutambura munzira dzakawanda, sezvo mutemo, kwakavakirwa mutemo hydraulic parameters munyika pechifukidziro. Asi pane zvimwewo kunzwisisa weathering inokanganisa kwete chete ivhu asiwo dombo. Muchiitiko ichi zvakakodzera kumutsa mubvunzo chii weathering zvicherwa? Izvi zvakare wechisikigo nedanho kuparadzwa, zvisinei, izvo, kungamuka kwete chete nokuda zvakanyanyisa aridity.

General ruzivo pamusoro weathering

Zvinoreva muitiro pasi weathering kwokunze kukanganisa padombo panguva iyo kuparadza kana manyowa kwayo zvinhu hwaro. Zvinhu zvichikonzera akadaro mananara vangava zvakasiyana hunhu - kubva mvura mumhepo nemakemikari. Kazhinji, zvicherwa anoita muzvizhinji akasiyana zvinhu, pakupedzisira zvichiita kuti Kuparadzwa padombo. Uye mubvunzo kuti zvakataurwa weathering, hatigoni kuvimba dzekare kunzwisisa mabasa mhepo zvakananga kana zvimwe exogenous zvinhu. Kunyange zvatinosiita zvemakemikari uye mumuviri pezvakaitwa hatinyatsonzwisisi kuratidza kuzara chiitiko ichi. Somuenzaniso, kuparadzwa anogona kuitawo uye maitiro gasi mabasa. Zvikurukuru, carbon dioxide uye okisijeni zvinopa chinoshingaira nokukanganisika kushanda. Chimwe chinhu ndechokuti preconditions navo vanogona chokuita nokuda kwebasa kwevanhu - somuenzaniso, mukati zvinoreva zvakafanana kurima.

mhando weathering

Kazhinji secrete makemikari omuviri weathering pezvakaitwa, anowanzoshandurwa dyidzana uye mukwanisi mumwe. Ndiko kuti kuchinyanya kwavo dzingasiyana zvichienderana dzezvakatipoteredza ezvinhu. Asiwo dzimwe dziri dzinotsanagura inotonhorera uye mwaranzi chokupfeka hazvizivani. Uyezve, chaizvo vakadaro mananara kazhinji zvikuru iziviswe kuparadzwa. Chemical uye mumuviri pezvakaitwa tiri zvoga uye zvinogona kunzi musiwa dzichingoridzwa hwaro, asi pamwe kunosiyana inosiyana simba pamusoro maumbirwo dzinongoitika zvinhu. Biogenic weathering mhando zvinogona kuva migumisiro kare zvikuru namakemikari manyowa.

Basa iri kupiwa chinhu weathering hakubvi chete kubva Kufurirwa nevamwe asiwo zvinoitwa padombo. Kakawanda, nyanzvi funga raora kuti zvakavapo. Saka, sezvo chikuru zvinoita kuti kuziva izvi kana zvimwe weathering pezvakaitwa, yoga okunze, kwakaita nzvimbo yacho features, tectonic maitiro, akafanana uye mamiriro padombo.

Process weathering

Pakati huru zvinokonzera kuti weathering nyanzvi mhando iyi kudana unopinza uye kugara tembiricha kuchinja. Kana masikati chicherwa pamusoro rinopisa uye anowedzera, usiku pakati kutonhora kwacho kunoshandurwa mamiriro reductions. Somugumisiro, Cracking kunoitika uye kupwanya matombo mukati nezvimedu zvidiki. mhando iyi deformation, izvo, zvakare, zvachose, kunyange unobtrusive. Kunyanya anzi mumuviri weathering munzvimbo inotonhora, apo kazhinji pane frosts. Chokwadi kuti nemamiriro zvicherwa kuomerera mwando panguva yakadaro munguva solidifies uye crystallizes, izvo anowedzera kunetsana uye zvareva kuti zvikuru Cracking. Batsirawo Kuti basa zvinoparadza uye vibration Mabhuku eBraille nechifukidziro, izvo kazhinji dzinoitika kusagadzikana panyaya tectonic kumatunhu ari mudziyo.

The mushonga weathering

Mananara zvakasikwa ichi zvinogona chokuita boka guru zvikonzero izvo haakonzeri payo kuparadzwa nguva dzose. Zvichienderana nemakemikari kukanganisa dombo mamiriro anogona kuonekwa uye deformation pezvakaitwa uye kuumbwa zvicherwa itsva. Vacho richava Qualitative Kuchinja murwiyo uye nemamiriro chinhu. In pakarepo zvinhu izvo Activate namakemikari weathering, ipai kure mvura, okisijeni uye carbon dioxide. Somuenzaniso, mvura zvinhu vokuitirwa nyasha nedombo solvent zvimwe mhando. Kuwanda kukurukurirana nemvura chicherwa kunoenderana makemikari anoumba Urume. Panguva iyoyowo, uye maitiro pacharo angava akasiyana. Saka, igneous dombo zvicherwa mvura kunokanganisa zvingaitwa ne hydrolysis. Its zvinogona yaitsiva alkali zvinhu nokuda rehydrogen ions.

Biogenic kana makemikari weathering

Sezvatotaurwa, hapana zvishoma nezvainoita zvicherwa anogona kupa uye chaivo zvinhu. Izvi zvinosanganisira basa zvinomera, nemakonzo diki uye kunyanya microbial notumwe uye utachiona. Pamwe chete, izvi zvingakonzera kugovera zvikuru Kuvhiringidza rikurumidze kupfuura mumuviri kana makemikari zvinhu. Asiwo kunobva zvakananga ezvinhu kwenzvimbo riri dombo. Chii hunhu biogenic weathering uchidzidzira? Zvingava Somuenzaniso, basa zvipenyu, kupwanya zvicherwa ivhu rukoko. Zvanzi anoshanda ari midzi miti. Zvimwe mhando chikwindi anogona kuita seinokonzera kwemakemikari kuita muchisunungura acid, vakazochinja ari yaora nomumwe zvinoriumba mugodhi conglomerate.

Features nemwaranzi weathering

Chimwe chezvinhu ngozi ndiyo muitiro nemwaranzi chokupfeka. It kunoratidzwa yakakwirira zvikuru uye nguva, uye kuamisa zvisingabviri muzviitiko zvakawanda. Asi pano zviri kupa dzinongoitika chezuva, inova chikamu boka nemwaranzi zvinhu, uye channel kwendangariro. Kana yechipiri, weathering wamatombo mugumisiro nemabasa evanhu. A muenzaniso chaiwo ibasa polygons izvo kuchengetera tsvina toxicologically ngozi. Saizvozvowo, rinotevera arrays matombo uye achava pasi kukuvadza, uye kushingaira chinhu manyowa.

Chii chiri weathering goko

Tichanzwisisa uye nyaya yacho. weathering pezvakaitwa anogona kuitika ichi- kana nguva. Asi zvose zviitiko, pose apo pane vamwe Qualitative zvikonzero zviri deformation, anowana anozivikanwa chitarisiko. Izvi zvichava weathering goko, ayo kuburikidza looseness uye dzakaonda makemikari anoumba inozivikanwa.

Kazhinji, okumusoro akaturikidzana akaturikidzana dzakadaro zvishoma yaora uye aikudzwa nokuvapo zvesimbi zvinoriumba. Zvinogona Somuenzaniso, hydroxides ose nesilicon kana aruminiyamu. Zvinotevera mapazi apo simbi hydroxides varipo, paumbwe yaiva achifurira namakemikari weathering nezvishoma zvokutamba. In rezasi akaturikidzana ari cortex kazhinji nhema reraimu uye gypsum concretions.

weathering zvinogadzirwa

Yemanyorero panguva weathering ibwe zvimedu zvasara, tudonhwe jecha, muturunhuru, ivhu uye kaolin zvikamu zviduku. Kana izvi akochonorwa kubva padombo zvinhu vangava inosiyana uye zvitarisiko - napo maduramazwi ezvinhu uye weathering zvikonzero. Mune zvimwe zviitiko zvinokwanisika uye paumbwe Kuruma. nemavhinga ichi chikuru uye boulders svezheoblomannyh aumba kubva-ataurwa pamusoro zvikamu zviduku. Standard hukuru siyana Kurume 1 2 metres, kunyange pane zviitiko kuti vaende zvikuru kupfuura kuti. Kakawanda, paumbwe akadaro kutigumbura kunopa utano weathering, izvo zvinogona kuguma kusika ibwe uye goko pamwe kurumovym flooring.

mhedziso

Weathering kunoitika kwete chete kunosiyana inosiyana pakudzama, asiwo zvakasiyana-siyana zvokukura Implementation. The nyore muenzaniso aizova muitiro kwomuviri kuparadzwa nemhaka tembiricha migumisiro. Uyezve, anogona kwakabatana uye makemikari maitiro umo mvura ine basa zvirimo zvichaparadzwa zvinobatanidzwa. Zvino zvakafanira kuti kutendeukira kuna mubvunzo zviri yezvakaita makemikari weathering. Neimwe ichi biodegradation muitiro, izvo zvinogona muropa kutungamirira kuti paumbwe itsva uye matombo. Saizvozvowo, weathering haagoni kunzi chete sezvo kuparadzwa aripo chicherwa. Kunyange kana deformation iri kupedziswa padariro kupatsanurwa yakasimba PARTICIPLE mumuviri, kuchinja uku kungawedzera nokuumbwa zvicherwa matsva kana conglomerates kuti asimbise kuvapo kwayo kurums.
