Txawm tias thaum nws rov qab los, cov dej khov tseem deforms thiab txav mus rau qhov chaw qis, zoo li siv txoj siv sia.
Yuav ua li cas koj thiaj paub yog tias lub qhov dej khov nce mus lossis thim rov qab?
4 Teb. Txoj kev yooj yim tshaj plaws yog saib cov ntug dej hiav txwv. Yog hais tias cov dej khov nyob rau hauv kev sib cuag nrog cov nroj tsuag los yog pob zeb nyob rau hauv lichens los yog moss, nws txhais tau tias nws yog feem ntau yuav nce mus. Yog koj pom ib pawg ntawm lub neej-tsawg pob zeb nyob nruab nrab ntawm cov dej khov thiab thawj cov nroj tsuag / lichens / moss, txhais tau tias nws rov qab.
Yuav ua li cas glacier nce mus es tsis txhob thim rov qab?
Lub Peb Hlis, ib pab neeg tshawb fawb uas NASA tau tshaj tawm tias Jakobshavn Isbrae, Greenland qhov nrawm tshaj plaws-ntws thiab thinning glacier dhau ob xyoo dhau los, tam sim no ntws qeeb dua, thickening thiab nce mus rau hauv dej hiav txwv es tsis txhob thim rov qab mus rau hauv av. Ntawm qhov chaw, lub suab zoo li xov xwm zoo.
Puas dej khov nce lossis txo qis?
Cov dej khov thoob ntiaj teb yog melting, thim rov qab thiab txawm ploj mus tag nrho. Tab sis nyob rau hauv roob Karakoram cheeb tsam ntawm Asia - lub tsev rau K2, lub thib ob-siab tshaj plaws ncov nyob rau hauv lub ntiaj teb no - lub glaciers tsis melting. Yog tias muaj dab tsi, qee qhov nthuav dav. Tam sim no, cov kws tshawb fawb tau pom ib qho kev piav qhia rau qhov tsis meej pem noglacial stability.
Puas yog qhov dej khov rov qab?
Ib lub glacier retreats thaum nws lub davhlau ya nyob twg tsis txuas mus deb li nram hav zoo li nws yav tas los ua. Glaciers yuav thim rov qab thaum lawv cov dej khov yaj los yog ablates sai dua li cov daus tuaj yeem sib sau thiab tsim cov dej khov tshiab.

Puas yog qhov siab tseem ceeb lossis thim rov qab?
Ib tsob txiv ntoo tuaj yeem muaj daim qauv ntawm cov noob siab uas tau sau rau "siab" thiab ib daim qauv ntawm tib cov noob uas tau sau rau "luv." Tab sis lub siab allele yog "dominant," txhais tau hais tias qhov siab-luv allele ua ke yuav ua rau tsob ntoo siab.
Qhov twg yog qhov laj thawj tseem ceeb rau kev thim rov qab / tig rov qab lub tswv yim?
Lub hom phiaj yog txo cov nqi, ua kom cov haujlwm ua haujlwm zoo, lossis ua kom cov nyiaj ntsuab ntws ruaj khov. Peb lub hom phiaj tseem ceeb ntawm kev thim rov qab yog: Txoj Cai Hloov Kho - Qhov no yog lub tswv yim tsim kho dua tshiab. Nws hu kom rov kho cov haujlwm kom tau nyiaj ntau dua lossis tau txais txiaj ntsig.
Puas rov tuav pov hwm rov qab xav tau cov neeg tuav pov hwm rov qab?
Cov tuam txhab tuav pov hwm rov qab feem ntau yuav rov ua pov hwm lawv tus kheej, lub sij hawm hu ua retrocession. Ntau txoj cai tau nthuav tawm ntawm ntau tus neeg tuav pov hwm rov qab. Nyob rau hauv rooj plaub no, qhov kev sib pauv yuav koom nrog tus thawj coj rov tuav pov hwm uas yuav sib tham txog cov ntsiab lus ntawm txoj cai uas lwm tus neeg tuav pov hwm rov qab yuav koom nrog.
Puas yog cov txheej txheem polytropic thim rov qab?
cov txheej txheem Polytropic yog internally reversible . Qee qhov piv txwv yog vapors thiab cov pa roj zoo meej gases Muaj peb chav kawm ntawm cov roj zoo tagnrho: classical lossis Maxwell-Boltzmann cov roj zoo tagnrho, qhov zoo tshaj plaws quantum Bose gas, muaj li ntawm bosons, thiab.
Puas yog cov tshuaj tiv thaiv enzymatic thim rov qab?
Vim feem ntau cov tshuaj tiv thaiv enzyme yog thim rov qab, ib qho enzyme tuaj yeem tsim thiab decompose molecules. Enzymes cov tshuaj tiv thaiv yog nyob ntawm ntau yam: pH, kub, thiab concentration ntawm ob qho tib si enzyme thiab substrate.
