Cov tshuaj tiv thaiv nyob rau hauv ib puag ncig txhua lub sijhawm, thiab cov no ua rau tshuaj lom neeg huab cua . Cov tshuaj tiv thaiv tseem ceeb muaj xws li carbonation, kev tawg hydration, hydrolysis , thiab oxidation-txo cov tshuaj tiv thaiv. Carbonation - thaum dej reacts nrog carbon dioxide, nws tsim carbonic acid, uas tuaj yeem yaj softer pob zeb.
Nyob rau hauv tas li ntawd, dab tsi yog dissolution nyob rau hauv huab cua?
Kev tawg yog ib txoj kev zoo tshwj xeeb ntawm cov tshuaj huab cua nyob rau hauv pob zeb uas muaj xws li magnesium carbonate los yog calcium carbonate, ob yam khoom uas yooj yim yaj los ntawm dej los yog lwm yam acidic daws.
Ib yam li ntawd, cov khoom ntawm huab cua yog dab tsi? Raws li huab cua tshwm sim, cov ferromagnesian silicates thiab feldspar muaj feem yuav raug tawg ua me me thiab hloov mus rau hauv av nplaum minerals thiab yaj ions (piv txwv li, Ca2+, Na+, K+, Fe2+, Mg2+, thiab H4SiO4). Hauv lwm lo lus, quartz, av nplaum minerals , thiab yaj ions yog cov khoom siv tshaj plaws ntawm huab cua.
Hauv qhov no, huab cua zoo li cas cuam tshuam nrog pob zeb tawg?
Chemical weathering hloov cov molecular qauv ntawm pob zeb thiab av. Piv txwv li, carbon dioxide los ntawm huab cua lossis av qee zaum ua ke nrog dej hauv cov txheej txheem hu ua carbonation. Qhov no ua rau cov kua qaub tsis muaj zog, hu ua carbonic acid, uas tuaj yeem yaj pob zeb. Carbonic acid yog tshwj xeeb tshaj yog zoo ntawm dissolving limestone.
Peb txheej txheem ntawm huab cua yog dab tsi?
Huab cua. Huab cua yog kev tawg ntawm pob zeb ntawm lub ntiaj teb nto, los ntawm kev ua dej nag, qhov kawg ntawm kub , thiab kev ua haujlwm lom neeg. Nws tsis koom nrog kev tshem tawm pob zeb khoom. Muaj peb hom huab cua, lub cev, tshuaj lom neeg thiab lom.
Pom zoo:
Yuav ua li cas rau igneous pob zeb uas undergo weathering?
Teb thiab piav qhia: Thaum cov pob zeb igneous raug huab cua thiab yaig, lawv tau tawg mus rau hauv me me ntawm sediment. Sediment yog ib txwm tshwm sim ntawm cov pob zeb
Yuav ua li cas compound yuav tsim yog Aluminium thiab oxygen tau ua ke?
Aluminium tuaj yeem hnov mob nrog cov pa oxygen los tsim cov txhuas oxide (Al_2O_3)
Yuav ua li cas yog peb txoj kev mechanical weathering tshwm sim?
Mechanical weathering yog kev tawg ntawm pob zeb rau hauv me me yam tsis hloov cov khoom muaj pes tsawg leeg hauv pob zeb. Qhov no tuaj yeem muab faib ua plaub yam yooj yim - abrasion, siab tso tawm, thermal expansion thiab contraction, thiab siv lead ua loj hlob
Yuav ua li cas muaj pes tsawg tus tooj liab atoms koj yuav tsum tau kab ntawm ib sab los tsim ib kab 1'm ntev?
Los ntawm kev sib piv, lub ntiaj teb cov pej xeem tsuas yog hais txog 7? 109 neeg. Yog tias koj tuaj yeem ua kab 100,000,000 tooj liab atoms ib sab, lawv yuav tsim ib txoj kab ntev li 1 cm
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
