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.
Pom zoo:
Dab tsi yog kev sib raug zoo ntawm mechanical waves thiab teeb meem?
Mechanical yoj yog nthwv dej uas yog qhov oscillation ntawm cov teeb meem, thiab yog li hloov lub zog los ntawm qhov nruab nrab. Thaum nthwv dej tuaj yeem txav mus deb, qhov kev txav ntawm qhov nruab nrab ntawm kev sib kis-cov khoom siv-yog txwv. Yog li ntawd, cov khoom siv oscillating tsis txav deb ntawm nws txoj haujlwm pib sib npaug
Chemical weathering kid definition yog dab tsi?
Ib hom huab cua hu ua chemical weathering siv tshuaj lom neeg los hloov pob zeb. Cov tshuaj tiv thaiv tshuaj tshwm sim thaum ib yam khoom tshwm sim nrog lub ntsiab lus, xws li oxygen, thiab qhov no hloov qhov nws tsim los ntawm. Qhov tshwm sim yog cov khoom tsim los ntawm cov khoom tshiab, thiab nws tsis tuaj yeem hloov rov qab
Dab tsi yog qhov txawv ntawm kinetic thiab mechanical zog?
Qhov txawv ntawm kinetic thiab mechanical zog yog tias kinetic yog ib hom ntawm lub zog, thaum mechanical yog ib daim ntawv uas lub zog siv. Piv txwv li, ib rab hneev uas tau kos thiab hneev taw uas yog lub xub yog ob qho piv txwv ntawm lub zog siv tshuab. Txawm li cas los xij, lawv tsis muaj ob hom tib lub zog
Plaub txheej txheem ntawm chemical weathering yog dab tsi?
Kawm txog ntau hom tshuaj huab cua xws li hydrolysis, oxidation, carbonation, acid nag thiab acids uas tsim los ntawm lichens. Chemical Weathering. Tej zaum koj yuav pom tias tsis muaj ob lub pob zeb zoo ib yam nkaus. Hydrolysis. Muaj ntau hom tshuaj tiv thaiv huab cua. Oxidation. Carbonation
Dab tsi yog electromagnetic thiab mechanical waves?
Electromagnetic yoj yog nthwv dej uas muaj peev xwm xa nws lub zog los ntawm lub tshuab nqus tsev (piv txwv li, qhov chaw khoob). Electromagnetic nthwv dej yog tsim los ntawm kev co ntawm cov khoom siv hluav taws xob. Mechanical yoj xav tau ib qho nruab nrab txhawm rau thauj lawv lub zog ntawm ib qho chaw mus rau lwm qhov
