Neeg kho tshuab / lub cev huab cua - lub cev disintegration ntawm lub pob zeb rau hauv me me fragments, txhua tus muaj tib yam khoom raws li tus thawj. Feem ntau tshwm sim los ntawm qhov kub thiab txias hloov pauv. Tshuaj tiv thaiv huab cua - txheej txheem los ntawm cov txheej txheem sab hauv ntawm cov pob zeb hauv av tau hloov pauv los ntawm kev ntxiv lossis tshem tawm cov ntsiab lus.

Ib yam li ntawd, koj tuaj yeem nug, qhov sib txawv ntawm cov huab cua huab cua thiab tshuaj huab cua yog dab tsi?

Mechanical weathering yog lub cev tawg ntawm pob zeb rau hauv me me. Tshuaj tiv thaiv huab cua yog qhov tawg ntawm pob zeb los ntawm tshuaj txheej txheem. Ice kuj tuaj yeem ua rau mechanical huab cua thaum dej nkag rau hauv cov pob zeb tawg, thiab tom qab ntawd khov thiab nthuav dav. Qhov no nthuav cov kab nrib pleb, ua rau mechanical huab cua.

Tom qab ntawd, lo lus nug yog, dab tsi yog piv txwv ntawm kev siv tshuaj lom neeg thiab kev siv huab cua? Nyob rau hauv cov huab cua tshuaj, lub pob zeb reacts nrog cov khoom nyob rau hauv ib puag ncig xws li oxygen, carbon dioxide, thiab dej los tsim cov khoom tshiab. Piv txwv li, hlau hauv pob zeb tuaj yeem hnov mob nrog oxygen thiab dej los ua xeb, ua rau lub pob zeb reddish thiab crumbly. Thaum lub sij hawm mechanical weathering, tsis muaj cov khoom tshiab tsim.

Xav txog qhov no, dab tsi yog mechanical weathering?

Mechanical weathering yog tus txheej txheem ntawm kev tawg pob zeb loj rau hauv me me. Cov txheej txheem no feem ntau tshwm sim ze ntawm qhov chaw ntawm lub ntiaj teb. Kub kuj cuam tshuam rau thaj av. Hmo ntuj txias thiab hnub kub ib txwm ua rau cov khoom nthuav dav thiab cog lus.

Puas muaj tshuaj tiv thaiv huab cua thiab kev siv tshuab huab cua ua haujlwm ua ke?

lub cev huab cua kuj hu ua mechanical weathering los yog disaggregation. lub cev thiab chemical weathering ua hauj lwm ua ke nyob rau hauv txoj kev complementary. chemical huab cua hloov cov pob zeb muaj pes tsawg leeg, feem ntau hloov lawv thaum dej cuam tshuam nrog cov zaub mov los tsim ntau yam tshuaj cov tshuaj tiv thaiv.
