Arête , (Fabkis: "ridge"), hauv geology , ib tug ntse-crested serrate ridge sib cais lub taub hau ntawm tawm tsam hav (cirques) uas yav tas los tau nyob los ntawm Alpine glaciers. Nws muaj kaum sab xis tsim los ntawm lub cev qhuav dej ntawm cov pob zeb uas tsis muaj kev txhawb nqa, undercut los ntawm kev khov thiab thawing (glacial sapping; saib cirque).
Tom qab ntawd, Arete yog dab tsi hauv thaj chaw?
Ib cov arête yog ib lub pob zeb nqaim uas cais ob lub hav. Nws yog feem ntau tsim thaum ob glaciers erodes parallel U-puab hav. Arêtes kuj tuaj yeem tsim tau thaum ob lub glacial cirques eroded headwards ntawm ib leeg, txawm hais tias feem ntau qhov no ua rau lub eeb-puab hla, hu ua col.
Tsis tas li ntawd, Arete nyob qhov twg? Ib tug paub zoo cov arête tsim yog lub ncov pyramidal hu ua Matterhorn. Nws yog nyob nyob rau hauv lub Alps ntawm ciam teb ntawm Switzerland thiab Ltalis.
Raws li, dab tsi yog lub horn hauv geology?
Ib tug arête yog ib tug nyias, crest ntawm pob zeb sab laug tom qab ob tug glaciers uas nyob ib sab tau hnav ib tug ntxhab ridge rau hauv lub pob zeb. A horn tshwm sim thaum glaciers erodes peb los yog ntau tshaj arêtes, feem ntau tsim ib tug ntse-edged ncov. Cirques yog concave, ncig basins carved los ntawm lub hauv paus ntawm glacier raws li nws erodes toj roob hauv pes.
Puas yog Arete erosion lossis deposition?
Lawv tsim nyob rau hauv roob thiab ntws los ntawm roob hav dej. Glaciers ua rau kev yaig los ntawm plucking thiab abrasion. Valley glaciers tsim ntau yam tshwj xeeb los ntawm kev yaig , suav nrog cirques, arêtes, thiab horns. Cov av uas tso los ntawm cov dej khov nab kuab muaj xws li drumlins, kettle pas dej, thiab eskers.

Dab tsi yog progradation hauv geology?
Nyob rau hauv sedimentary geology thiab geomorphology, lub sij hawm progradation yog hais txog kev loj hlob ntawm tus dej delta tawm mus rau hauv hiav txwv dhau sij hawm. Kev loj hlob tuaj yeem tshwm sim los ntawm: Lub sijhawm ntawm lub caij nplooj zeeg dej hiav txwv uas ua rau dej hiav txwv regression
Dab tsi yog kev ntxhov siab thiab kev nyuaj siab hauv geology?
Kev ntxhov siab yog lub zog ua haujlwm ntawm lub pob zeb hauv ib cheeb tsam. Txhua lub pob zeb tuaj yeem strained. Cov tawv nqaij tuaj yeem yog elastic, nkig, los yog ductile. Ductile deformation kuj hu ua yas deformation. Cov qauv hauv geology yog cov yam ntxwv deformation uas tshwm sim los ntawm kev ruaj khov (nkig lossis zawm)
Dab tsi yog mudflow hauv geology?
Ib qho av nkos los yog av nkos yog ib hom kev nkim loj uas cuam tshuam nrog 'hloov nrawm heev mus rau qhov nrawm nrawm' ntawm cov khib nyiab uas tau dhau los ua ib feem lossis tag nrho cov kua dej los ntawm qhov sib ntxiv ntawm cov dej tseem ceeb rau cov khoom siv
Stereonet yog dab tsi hauv geology?
Lub stereonet yog ib qho qis hemisphere daim duab uas muaj ntau yam ntaub ntawv geological tuaj yeem npaj tau. Stereonets yog siv nyob rau hauv ntau ntau ceg ntawm geology thiab yuav siv tau nyob rau hauv ntau txoj kev tshaj li cov uas tau tham ntawm no (saib cov ntaub ntawv rau kev siv ntxiv)
Dab tsi yog ntu nyias hauv geology?
Nyob rau hauv kho qhov muag mineralogy thiab petrography, ib tug nyias (los yog petrographic nyias seem) yog ib lub chaw kuaj pob zeb, ntxhia, av, lauj kaub tais diav, pob txha, los yog txawm hlau qauv siv nrog ib tug polarizing petrographic microscope, electron microscope thiab electron microprobe
