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 .
Yog li ntawd, dab tsi yog cov txheej txheem ntawm chemical weathering?
Cov tshuaj tiv thaiv tseem ceeb cuam tshuam nrog kev siv tshuaj lom neeg huab cua yog oxidation , hydrolysis , thiab carbonation. Oxidation yog cov tshuaj tiv thaiv nrog oxygen los tsim cov oxide, hydrolysis yog cov tshuaj tiv thaiv nrog dej, thiab carbonation yog cov tshuaj tiv thaiv nrog CO2 tsim ib carbonate.
Ib sab saum toj no, dej koom nrog hauv cov hom tshuaj tiv thaiv huab cua li cas? Tshuaj tiv thaiv huab cua tshwm sim thaum dej dissolves minerals nyob rau hauv ib lub pob zeb, tsim cov tebchaw tshiab. Qhov no tshuaj tiv thaiv hu ua hydrolysis. Hydrolysis tshwm sim, piv txwv li, thaum dej tuaj nyob rau hauv kev sib cuag nrog granite. Feldspar crystals hauv granite tshuaj tiv thaiv , tsim av nplaum minerals.
Kuj Paub, 5 hom tshuaj tiv thaiv huab cua yog dab tsi?
Tsib qhov piv txwv tseem ceeb ntawm cov huab cua huab cua yog oxidation, carbonation, hydrolysis, hydration thiab lub cev qhuav dej
- Reacting Nrog Oxygen. Cov tshuaj tiv thaiv ntawm pob zeb thiab oxygen yog hu ua oxidation.
- Dissolving hauv Acid.
- Sib tov nrog dej.
- Absorbing dej.
- Tshem Tawm Dej.
Dab tsi yog 4 yam uas cuam tshuam rau huab cua?
KEV PAB CUAM: Tus nqi ntawm cov dej hauv huab cua thiab cov kub ntawm ib cheeb tsam yog ob feem ntawm ib cheeb tsam kev nyab xeeb. Moisture ua kom cov huab cua chemical. Huab cua tshwm sim sai tshaj plaws hauv cov huab cua kub, ntub dej. Nws tshwm sim qeeb heev hauv cov huab cua kub thiab qhuav.

Dab tsi yog 6 theem ntawm cov txheej txheem ntawm lub cev?
Qib ntawm Cov Txheej Txheem Txheej Txheem: Txhua yam yog tsim los ntawm cov khoom me me, los ntawm cov subatomic hais, mus rau atoms, molecules, organelles, hlwb, cov ntaub so ntswg, cov kabmob, cov kab mob hauv nruab nrog cev, cov kab mob thiab thaum kawg biosphere. Hauv tib neeg lub cev, feem ntau muaj 6 theem ntawm lub koom haum
Dab tsi yog txheej txheem spontaneous thiab non-spontaneous txheej txheem?
Cov txheej txheem spontaneous yog ib qho uas tshwm sim yam tsis muaj kev cuam tshuam ntawm sab nraud. Ib txoj kev uas tsis yog tshwm sim yuav tsis tshwm sim yog tias tsis muaj kev cuam tshuam ntawm sab nraud
Qhov twg ntawm cov plaub hau plaub hau yog ib txwm plaub hau plaub hau?
square Tsis tas li ntawd nug, qhov ntsuas ntawm ib lub quadrilateral tsis tu ncua yog dab tsi? Yog, sab hauv lub kaum sab xis ntawm txhua lub ces kaum ntawm ib lub quadrilateral tsis tu ncua yog txhua 90 degrees (360 degrees / 4 fab).
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
Cov txheej txheem twg yog txheej txheem endothermic?
Cov txheej txheem endothermic yog ib qho txheej txheem uas xav tau lossis nqus lub zog los ntawm nws qhov chaw nyob ib puag ncig, feem ntau yog ua kom sov. Nws yuav yog cov txheej txheem tshuaj, xws li dissolving ammonium nitrate hauv dej, lossis cov txheej txheem ntawm lub cev, xws li melting ntawm cov dej khov nab kuab
