Qhov twg nws tshwm sim ? Cov no tshuaj cov txheej txheem xav tau dej, thiab tshwm sim ntau ceev ceev ntawm qhov kub thiab txias, yog li sov, damp climates yog qhov zoo tshaj plaws. Tshuaj tiv thaiv huab cua (tshwj xeeb tshaj yog hydrolysis thiab oxidation) yog thawj theem ntawm kev tsim cov av.
Ib yam li ib tug yuav nug, qhov twg yog huab cua huab cua tshwm sim sai tshaj?
Cov dej noo nrawm chemical huab cua . Huab cua tshwm sim sai tshaj plaws nyob rau hauv cov huab cua kub, ntub dej. Nws tshwm sim qeeb heev hauv huab cua kub thiab qhuav. Yog tias tsis muaj qhov kub thiab txias, kev sib tsoo dej khov tsis tuaj yeem tshwm sim.
Ib sab saum toj no, huab cua feem ntau yuav tshwm sim qhov twg? Qhov tshwm sim ntawm huab cua ntawm los yog ze ntawm lub ntiaj teb saum npoo kuj txawv nws ntawm lub cev thiab tshuaj hloov pauv ntawm pob zeb los ntawm metamorphism, uas feem ntau yuav siv qhov chaw tob hauv lub pob zeb ntawm qhov kub thiab txias.
Ntawm no, qhov twg carbonation weathering tshwm sim?
Carbonation tshwm sim ntawm cov pob zeb uas muaj calcium carbonate, xws li limestone thiab chalk. Qhov no tshwm sim thaum nag los ua ke nrog carbon dioxide los yog cov organic acid los ua ib qho tsis muaj zog carbonic acid uas reacts nrog calcium carbonate (limestone) thiab tsim calcium bicarbonate.
chemical weathering process yog dab tsi?
Tshuaj tiv thaiv huab cua yog cov txheej txheem los ntawm cov pob zeb uas tawg los ntawm tshuaj cov tshuaj tiv thaiv. Thaum hlau nyob rau hauv pob zeb reacts nrog oxygen, nws tsim hlau oxide, uas ua rau lub pob zeb tsis muaj zog. Carbonation yog sib tov dej nrog carbon dioxide los ua carbonic acid. Hom no huab cua yog ib qho tseem ceeb hauv kev tsim cov qhov tsua.

Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Qhov txheej twg yog huab cua tshwm sim feem ntau tshwm sim?
Troposphere. Lub troposphere (los ntawm Greek: tropein - hloov, ncig lossis sib xyaw) yog txheej qis tshaj plaws ntawm lub ntiaj teb huab cua. Feem ntau ntawm huab cua phenomena, systems, convection, turbulence thiab huab tshwm sim nyob rau hauv no txheej, tab sis tej zaum yuav mus rau hauv lub qis feem ntawm thestratosphere
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
Mechanical weathering thiab chemical weathering yog dab tsi?
Mechanical/physical weathering - lub cev disintegration ntawm ib 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. Chemical weathering - txheej txheem uas cov txheej txheem sab hauv ntawm cov ntxhia hloov pauv los ntawm kev ntxiv lossis tshem tawm cov ntsiab lus
