Muaj peb yam tseem ceeb ntawm kev yaig glacial - plucking, puas thiab khov thaw. Plucking yog thaum yaj dej los ntawm ib qho dej khov khov nyob ib ncig ntawm pob zeb tawg thiab tawg. Thaum cov dej khov txav mus rau pem hauv ntej, pob zeb yog plucked los ntawm phab ntsa tom qab.
Kuj paub, dab tsi yog qhov cuam tshuam ntawm glacial yaig?
A glacier cov qhov hnyav, ua ke nrog nws maj mam txav mus, tuaj yeem hloov kho cov toj roob hauv pes ntau pua lossis ntau txhiab xyoo. Cov dej khov erodes thaj av thiab nqa cov pob zeb tawg thiab cov av khib nyiab deb ntawm lawv qhov chaw qub, ua rau qee qhov nthuav. glacial daim av.
Tsis tas li ntawd, qee qhov piv txwv ntawm glacial yaig? Ib qho tseem ceeb tshaj plaws piv txwv yog ib tug loj trough txoj cai nyob rau hauv nruab nrab ntawm lub teb chaws uas tsim los ntawm ib tug dej khov txav maj mam hla nws. Dej khov pas dej yog piv txwv ntawm dej khov kev yaig . Lawv tshwm sim thaum a dej khov carves nws txoj kev mus rau hauv ib qho chaw thiab tom qab ntawd melts lub sij hawm, sau qhov chaw uas nws carved tawm nrog dej.
Tsis tas li ntawd, cov txheej txheem glacial yog dab tsi?
Cov txheej txheem glacial
- Abrasion - Glaciers nqa ntau cov khoom nrog lawv.
- Plucking - Qhov no yog lub ntsiab erosive txheej txheem ntawm lub glacier.
- Freeze-Thaw - Dej nkag rau hauv cov pob zeb thaum nruab hnub.
- Glaciers nqa cov khoom loj heev.
Qhov twg glacial yaig tshwm sim?
Dej khov yog cov nplooj ntawv ntawm cov dej khov thiab cov daus uas npog thaj tsam loj ntawm thaj av. Lawv tsim nyob rau hauv qhov chaw uas qhov kub thiab txias feem ntau yog qis dua khov. Qhov no tuaj yeem nyob ze ntawm tus ncej qaum teb thiab sab qab teb, thiab tseem nyob rau hauv av siab heev, xws li roob loj.

Dab tsi yog cov txheej txheem tsim nyog rau kev ntxuav cov cuvettes?
Ua ntej siv, cuvettes yuav tsum tau ntxuav kom tshem tawm cov seem seem. Yog tias cov cuvettes zoo li huv si, tsuas yog yaug ob peb zaug nrog dej distilled, tom qab ntawd ib zaug nrog acetone (kom tsis txhob muaj dej) thiab tawm mus rau huab cua qhuav nyob rau hauv txoj hauj lwm inverted (xws li ntawm cov ntaub so ntswg) ua ntej siv

Dab tsi yog txheej txheem spontaneous thiab non-spontaneous txheej txheem?

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
