The usoro nke denudation

denudation

Denudation - demolition weathered ihe onwunwe site flushing planar mezuo iwu na ike ndọda, na mgbe ha ìgwè n'elu. Agents of denudation bụ: ndọda ije, na-arụ ọrụ nke na-agba ọsọ mmiri (mmiri ozize), ala na elu mmiri (karst, suffusion), ice na snow (nivation, exaration), ifufe (deflation), surf (abrasion), ndụ ntule (human). denudation osisi ike kpebisiri ike site ego nke sedimenti, osụk osimiri, kpụkọrọ kwa unit oge. Denudation enyemaka forms bụ:

• Self-denudation

Na a sara mbara uche - elu mere n'ihi na cumulative mmetụta nke niile mgbagwoju denudation Filiks (eg peneplain ma ọ structurally iche iche iche iche denudation.

Na warara uche - kpughere n'elu n'ihi ndọda mmegharị na planar flushing (ogidi, niches, ledges, na-amụkwasị)

Peneplain - slabovskholmlennaya Araba, guzobere usoro nke ogologo oge denudation nke dị n'ókèala oge ochie ugwu ugwu. N'ihi na oge mbụ a okwu e chepụtara site American geologist William Morris Davis, na nke iri na itoolu na narị afọ. Usoro denudation mere na iru mmiri ihu igwe na ọnọdụ (nke ukwu nke ọdịda karịa nwere ike ikusi na a ga-etinye obi gị dum n'ime ala ruru ka a na-kpụrụ ọtụtụ osimiri na iyi, ime ozize na mpaghara).

Eaves - snowy ugwu na-akụziri, ịda n'okpuru nduzi nke ifufe na ridges na ọnụ ọnụ.

Nis - na ezumike na ala nke ngwe n'ụsọ abrasion n'ihi ebibi ihe nke surf eruba.

• Ozize - elu mepụtara na-agba ọsọ mmiri (ndagwurugwu erosive mpụga, oche).

Ledges - akụkụ nke ọkpụrụkpụ nke nkume n'ụdị a ogbo kwadebere maka mmepe nke ịnweta ego.

Ozize Ofel - teres, esịnede mmadụ hiwere na uko ụlọ instrativnym a mkpa alluvium. Nke a bụ ndị kasị ochie ụdị mpụga, nke a nnukwu elu.

• Abrasion - mepụtara oké osimiri na ọdọ abrasion (bench, bench, niche, abrasion mpụga).

Abrasion mpụga (bench) - ala gbara osimiri okirikiri akụkụ nke elu nke n'ala oké osimiri ahụ, kọwakwuru site abrasion.

• Ekzaratsionnye - na-arụ ọrụ site kpụkọrọ (mbara ọzara, anētiye, mutton n'egedege ihu).

Anētiye - ochie ice ndagwurugwu na ebe nke a trough ekara transverse profaịlụ, obosara ala na nkpoda concave n'akụkụ, nke na-ejikọrọ na eme nke kpụkọrọ akọ. The longitudinal profaịlụ trough ndagwurugwu n'ozuzu nwere a steepụ udi nke òkè ọzọ overdeepened (vypahivaniya ọdọ mmiri) na-akpọlite nkume nzọụkwụ (bolts).

Ovine n'egedege ihu - ahazi ihu kpụrụ edinam (ije) glasia. Ọtụtụ n'akụkụ obere mutton n'egedege ihu, mgbe ụfọdụ, a na-akpọ mgbakọ nkume. Na Russia, ebe nile na Baltic ọta (Kola Peninsula). Ovine n'egedege ihu n'elu na-ntekwasa na a mkpa oyi akwa nke sod na obere mpekere mfe gbanwere n'okpuru ibu na-amị amị n'ihi seeping mmiri.

• Nival - malitere na ndị snow akara (akara), dị ka a n'ihi nke ntu oyi weathering (nivatsionnye niche ụgbọala, egwuregwu).

Kara - onye nke forms nke enyemaka, na-anọchi anya cup ekara ịda mbà n'obi na apical akụkụ nke ugwu mkpọda. Kara nwere nkpoda akụkụ ha na a ewepụghị ike, aku na ụyọkọ glasia firn na snow. Na nsọtụ nke carats odude crossbars.

Ọgbọ egwuregwu - Basin n'ugwu, na-emechi elu njedebe nke ice ndagwurugwu.

• Deflation - mere site ifufe (niches, ntupu, ụgbụgbọ mmanụ aṅụ, aeolian mushrooms, Sor-deflationary ịda mbà n'obi).

Eolian mushrooms - a ụdị enyemaka na-adị ka a n'ihi nke ifufe na corrosion. Ka ifufe na-eburu ahụ tumadi na elu elu, ala òkè nke nkume-eyi ala na-esichara site na ifufe siri ike. N'ihi ya, e eolian landforms, ma ọ bụ dịkwa ka usoro ha-dị ka okporo osisi na a mkpa azuokokoosisi.

• Karst - pụta si mgbasa (Ponor, funnels, n'oghere, abaitiat).
• Manmade - bilie na N'ezie nke mmadụ ulo oru ọrụ (ọwa, mines, mounds).

mmiri n'okpuru osimiri

1. Ndọda (slide).
2. Ozize (mmiri n'okpuru osimiri na ndagwurugwu, omimi).

Ụgbọ agha okpuru mmiri dị omimi - ndagwurugwu na mkpọda ugwu, bee n'ime continental shelf na continental mkpọda. Ụfọdụ n'ime ha bụ mmiri n'okpuru osimiri ndọtị estuaries, ebe ndị ọzọ na-adịghị mkpa nke ugbu a osimiri. Si n'ọnụ Ganga 1000 kilomita na ndị Bay of Bengal erukwa okpuru mmiri kaniyon obosara 7 km na a omimi nke 70 m. P Canyon. Congo ike deere na a anya nke 260 km omimi nke 2.150 m. Site p. Hudson amalite kaniyon, ndinyanade mbịne kwupụta oké osimiri banyere 400 km. Na mpaghara nke US Pacific n'ụsọ oké osimiri shelf bụ nnọọ warara, na omimi bụ miri emi ma nwere ná mkpọda ugwu. Monterey Canyon ụsọ oké osimiri nke California na mgbe ụfọdụ a tụnyere ndị Grand Canyon.
