Pfungwa denudation

denudation

Denudation - kuparadzwa weathered acho Flushing planar kuchiva nerukudzo, uye pashure kuwanda kwavo pamusoro pemvura. Vaishandira denudation vari: rinokweva kufamba, basa pemvura (kukurwa kwevhu mvura), pasi uye mvura (karst, suffusion), chando uye chando (nivation, exaration), mhepo (deflation), egungwa (abrasion), zvipenyu (human). denudation kuchinyanya pakutsvaga uwandu emadhaka, akabvuma nzizi, mazizaya muzana chikwata nguva. Denudation ruyamuro siyana vari:

ivhu

• Self-denudation

Mupfungwa yakakura - pose kunokonzerwa nokuda tinofanira kugara migumisiro zvose zvakaoma denudation pezvakaitwa (eg peneplain kana zvayakaita zvakasiyana siyana denudation.

In yakamanikana Mupfungwa - iri pachena pamusoro nokuda rinokweva kufamba uye planar Flushing (mbiru, niches, pemidengerero, rinoteura)

Peneplain - slabovskholmlennaya bani, kuumbwa nedanho refu denudation munharaunda yemakomo yekare. Kokutanga ino izwi rakatangwa neAmerican geologist William Morris Davis, negore regumi namapfumbamwe remakore. Process denudation kwakaitika nyorovera mamiriro okunze (uwandu kuti kunayisa pane anogona sasana uye nyura muvhu nokuda ichi chakaumbwa nenzizi zhinji uye nehova, kuwedzera kupera iri nzvimbo).

Eaves - chando makomo dzidzo, yomuka achifuridzirwa mhepo pamusoro anooneka zvikuru nemichinjiziri uye twi.

NIS - the pataimbozorora pasi Musara pamahombekombe abrasion kunokonzerwa risa yacho egungwa kuyerera.

• Kukurwa kwevhu - pamusoro yakataurwa pemvura (pamipata erosive tenuka, mabhenji).

Pemidengerero - chikamu pakukora matombo muchimiro mudariro yakagadzirirwa kukura chicherwa deposits.

Kukurwa kwevhu chinjiri - chinjiri, rinoumbwa bedrock uye ceilings instrativnym nhete alluvium. Ndicho chimiro kupfuura yekare tenuka, sezvamakaropafadzwa guru yakakwirira.

• Abrasion - dzakabudirira gungwa uye nyanza abrasion (zvigaro, Bench, niche, abrasion tenuka).

Abrasion tenuka (Bench) - kumahombekombe chikamu pemvura pegungwa, akarondedzera nokuda abrasion.

• Ekzaratsionnye - vakashanda nesimba mazitombo echando (mapani, muzvinwiro, mutton pahuma).

Zvimwiro - glacial yekare mumupata munzvimbo imwe muchimwiro serin'i transverse Profile, yakafara nechepasi uye pamawere concave mativi, izvo kwakabatana mumabasa mazizaya wakarimwa. The longitudinal Profile muchimwiro mumipata kazhinji vane akapindira chimiro umo migove Alternate overdeepened (vypahivaniya madziva) pamwe vanomutswa matombo matanho (kukurova).

Ovine pahuma - woita Musara kuumbwa chiito (kufamba) rechando. Several pedyo duku mutton pahuma, dzimwe nguva inonzi rakamonana matombo. MuRussia, kwakapararira kuBaltic nhoo (Kola Peninsula). Ovine pahuma pamusoro zvinenge zvakazara nhete paiva pevhu nemarara duku nyore zvakachinja pasi mutoro uye itsvedze nemhaka seeping mvura.

• Nival - zvakatanga panguva chando mutsetse (mutsetse), somugumisiro chando weathering (nivatsionnye niche motokari, circuses).

Kara - mumwe nzira kuzorodzwa, rinomirira mukombe serin'i mwoyo mune apical chikamu makomo dzakatenuka. Kara vane pamawere marata omumativi uye sandara pasi, kuroorana pamwe sumbu rechando firn uye chando. Kumucheto carats yaiva mbariro.

Circus - Basin mumakomo, nokuvhara rokumusoro kuguma glacial mumupata.

• Deflation - kunokonzerwa mhepo (niches, pajira riya, rouchi, aeolian howa, sor-deflationary mwoyo).

Eolian Howa - mufananidzo kuzorodzwa kunoitika pamusana mhepo uye ngura. Sezvo mhepo anotakura nezvimedu kunyanya panguva pemvura, migove yamatombo yaipfekwa pasi uye kupatsanurwa nemhepo kusimba rezasi. Naizvozvo eolian landforms, kana notumwe-kufanana mapango nhete hunde.

• Karst - dzakabuda kuparadzwa (Ponor, funnels, zvanza, mumapako).
• Manmade - rakamuka kosi kwevanhu maindasitiri basa (migero, zvimbambaira, pazvikomo).

pasi pemvura

1. Rinokweva (nemasiraidhi).
2. Kukurwa kwevhu (pemvura mumipata, canyons).

Yepasi pemvura canyons - mupata pamwe kumawere racherwa Continental pasherefu uye Continental materu. Vamwe vavo vane pemvura chiwedzerwa estuaries, vamwe havasi kuhupenyu magetsi nzizi. Kubva muromo Ganga 1000 makiromita ari Bay pamusoro Bengal kunosvika yepasi pemvura kanjoni upamhi 7 km uye kudzika 70 m. P Canyon. Congo dzinogona kurondwa ari chinhambwe 260? Km kuti kudzika 2,150 m. Kubva p. Hudson rinotanga canyon, Munotatamura kugungwa pamusoro 400? Km. Munzvimbo iri US Pacific Coast pasherefu yakamanikana chaizvo, uye canyons vari yakadzika uye vane kumawere. dzimwe nguva Monterey Canyon nemhenderekedzo California rinofananidzwa Grand Canyon.
