Raws li cov dej thiab cua maj mam eroded thiab disintegrate pob zeb nto, lawv txo cov roob nyob rau hauv ib tug series ntawm pediments nyob rau hauv lub hauv paus, thiab cov pediments maj mam nqes hav mus rau sab nraud, qhov chaw uas lawv coalesce nrog rau ib leeg. daim ntawv ib lub tiaj loj, uas yog lub pediplain.

Raws li txoj cai, pediment tsim li cas?

A pediment yog ib tug maj mam sloping yaig nto los yog tiaj tiaj uas tsis tshua muaj nyem tsim los ntawm kev khiav dej hauv cheeb tsam arid lossis semiarid ntawm lub hauv paus ntawm lub roob rov qab. A pediment yog underlain los ntawm bedrock uas feem ntau yog them los ntawm ib tug nyias, discontinuous veneer ntawm av thiab alluvium muab los ntawm upland cheeb tsam.

Ib sab saum toj no, Peneplain thiab Pediplain yog dab tsi? Hauv geomorphology thiab geology a peneplain yog lub tiaj tiaj tiaj uas tsim los ntawm kev yaig ntev. Peneplains Qee zaum muaj feem cuam tshuam nrog lub voj voog ntawm kev yaig txoj kev xav ntawm William Morris Davis, tab sis Davis thiab lwm tus neeg ua haujlwm kuj tau siv lo lus los piav qhia meej yam tsis muaj kev xav lossis kev xav tshwj xeeb txuas nrog.

Ib tug kuj yuav nug, leej twg muab lub tswvyim ntawm Pediplain?

Cov tswvyim ntawm pediplain thiab pediplanation yog thawj zaug tsim los ntawm geologist Lester Charles King nyob rau hauv nws 1942 phau ntawv South African Scenery. Cov tswvyim tau txais notoriety raws li nws yog juxtaposed rau peneplanation. Pediplains feem ntau yog tsim nyob rau hauv cov cheeb tsam ntawm arid thiab semi-arid kev nyab xeeb.

Pediplain yog dab tsi hauv geography?

Pediplain , broad, kuj tiaj pob zeb nto tsim los ntawm kev sib koom ntawm ob peb pediments. Pediplains feem ntau yog tsim nyob rau hauv arid los yog semi-arid huab cua thiab tej zaum yuav muaj ib tug nyias veneer ntawm sediments. Nws yog postulated tias lub pediplain tej zaum yuav yog theem kawg ntawm landform evolution, qhov kawg tshwm sim ntawm cov txheej txheem ntawm erosion.
