Rakadii ivhu jecha?

Zviri nyore kufunga pamhenderekedzo kana uchitaura nezvevhu rejecha. Uye zvechokwadi, munzvimbo ino kazhinji hapana chinhu, zvirinani kwete pamberi pegungwa. Ehezve, izvi hazvingagone kuve zvimwe, sezvo padyo negungwa chirimwa pachinokura, zvinovaka muviri zvishoma zvaichakwanisa kuwana uye nekuchimbidza ichafanira kugadzirisa kune nharaunda ine huwandu hwakawanda hwemunyu.

Asi chokwadi ndechokuti kune marudzi mazhinji ejecha, saka hapana mhando imwechete yevhu ine jecha. Neichi chikonzero, isu tine mukana wekugadzira gadheni rakanaka pane iyo ivhu. Kumwe kugadzirisa kunogona kuve kuri madikanwa, asi zvirokwazvo hazvisi zvisina musoro kufungidzira parutivi paradhiso mudiki munzvimbo yakadaro.

Hunhu hwevhu jecha

Ivhu rejecha nderimwe rine chikamu chakakura kwazvo chejecha (chinopfuura makumi manomwe kubva muzana), chine granulometry yayo iri pakati pe70 ne0,004mm Yayo yemanyowa yezvinhu zvemukati yakadzika kwazvo, asi kune rimwe divi irwo rudzi rwevhu rine rakanakisa kubuda.. Kuve wakareruka uye unopisa kwazvo, mvura inosvinwa nekukurumidza. Asi ichi zvakare chinokanganisa, sezvo chisinganyatso chengetedze hunyoro, kuitira kuti chete zvirimwa zvine mashoma ezvekudya zvinovaka muviri ndizvo zvinokwanisa kukura mairi.

Zvinoenderana nekwakabva jecha, ivo vanosiyaniswa kubva pamhando nhatu dzakasiyana:

• Alluvial jecha: ndiyo inotakurwa nemvura, senge yerwizi. Haina kukanganiswa kudaro, saka mhando huru yemiti inogona kukura mairi.
• Jecha remhepo: yakapfuma muquartz kana carbonates, uye ndiyo inoiswa nemhepo, semuenzaniso, mumadunduru nemabhishi.
• Residual jecha: imhedzisiro yekusakara kwematombo akapfuma mugranite, quartz kana sandstone.

Mhando dzevhu rejecha

Zvichienderana nechimiro uye patiri, tinogona kusiyanisa mhando dzakasiyana dzevhu rejecha:

Nzvimbo dzakaoma

Ivhu rejecha munzvimbo dzakaoma rinowanzove rakapfuma muquartz kana carbonates, uye inoumbwa kubva kumhepo jecha. Iko kune yakaderera huwandu hwenuturu, uye yakadzika kwazvo hunyoro hwekuchengetedza hunyanzvi. Semuenzaniso, isu tichaona izvi mumarenje, uko chete zvimwe zvinomera zvinokwanisa kukura munzvimbo shoma idzo uko kune yakawanda mvura uye zvinovaka muviri.

Nzvimbo dzakadzikama

Iyo iri munzvimbo dzinodziya inoumbwa kubva kune ese jecha jecha. Kazhinji, kunobva kumatangi emvura izvo zvakaumbwa mukati menguva yechando; kunyangwe ichigona zvakare kutakurwa kubva kugungwa, kana kunyangwe nemhepo.

Nzvimbo dzine hunyoro

Mune aya marudzi enzvimbo, sekugara kuchinaya, jecha rejecha rinowanzo kuve diki, rinouya kubva kujecha rinounzwa nemvura kana nemhepo. Zvisinei, sezvo matombo anopera, iwo zvakare anogadzira ivhu.

Ivhu rejecha rinowanikwa kupi?

Ivhu rejecha Inowanikwa kunyanya munzvimbo dzakawoma uye dzakaomesesa zvepasi, asi muchokwadi kune zvakare kuri mune nyoro mamiriro ekunze. Chero zvazvingaitika, iwe unofanirwa kuziva kuti irimo mumarenje, senge Sahara mu Africa kana Sonora kuNorth America. MuAustralia yakawanda dunhu rayo ivhu rine jecha, kunyanya nzvimbo dzepakati nekumadokero.

Kana tikagara kuSpain, tine nzvimbo dzose. Uye zvakare, muAndalusia pane iyo iri pamhenderekedzo yeCádiz, Almería neHuelva.

Nzira yekuvandudza ivhu jecha?

Tichifunga kuti izvo zviviri zvipingaidzo zverudzi urwu rwevhu ndiko kushomeka kwezvinhu zvakasikwa kune rimwe divi, uye nehurombo hwekuchengetedza mvura, izvo zvatingaite kuzvinatsiridza zvinotevera:

Ipai mafotereza ehupenyu

Zvakadai semanyowa ehuku kana guano. Ose ari maviri ane hupfumi hwakanyanya, saka anozoshanda kuita kuti ivhu riwedzere kubereka, uyezve zvishoma nezvishoma kuchengetedza hunyoro.

Paradzira hutete hwakakora, ungangoita masendimita gumi padivi, munzvimbo yese yaunoda kugadzirisa, wosanganisa nebadza kana, kana uine kufamba tarakita. Dzokorora nguva nenguva, kamwe chete pamwedzi kana pamwedzi miviri yega yega.

Raira rori revhu revhu, kana riine silty

Paunenge uchimhanyisa, uye ivhu riine jecha, dzimwe nguva mhinduro yakanakisa ndeyekusarudza kukumbira rori rakazara nevhu kana ivhu rakapfuma kuti riunzwe. Kana uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinge uchinayo, inosangana zvakanaka nevhu ratinaro uye ndizvozvo. Nekudaro, iwe ungatofanira kukumbira zvimwe nekufamba kwenguva, sezvo mvura uye / kana mhepo inogona kudzorera ivhu kumamiriro aro epakutanga.

Ndezvipi zvirimwa zvinogona kurimwa muvhu jecha?

Kana iwe uine ivhu jecha uye iwe usingazive izvo zvirimwa zvekukura, tinokurudzira zvinotevera:
