Lithification yog cov txheej txheem los ntawm cov sediments sib xyaw ua cov pob zeb sedimentary. Compaction yog aconsolidation ntawm sediments vim qhov hnyav nias ntawm overlying deposits. Nrog compaction, sediment nplej tau squished ua ke, txo qhov luaj li cas ntawm thawj qhov chaw pore uas faib lawv.
Hauv qhov no, Lithification tshwm sim qhov twg?
Lithification . Lithification , complex txheej txheem whereby freshly deposited xoob nplej ntawm sediment yog hloov dua siab tshiab rau hauv pob zeb. Lithification muaj tshwm sim thaum lub sij hawm muaj sediment yog tso nyiaj los yog tom qab. Cementation yog ib qho ntawm cov txheej txheem tseem ceeb koom nrog, tshwj xeeb tshaj yog rau sandstones thiab conglomerates.
Qhov thib ob, koj txhais li cas los ntawm Lithification? Lithification (los ntawm Ancient Greek lo lus lithos lub ntsiab lus 'pob zeb' thiab Latin-derived suffix -ific) yog cov txheej txheem uas cov sediments compact nyob rau hauv siab, tshem tawm connatefluids, thiab maj mam ua pob zeb. Qhov tseem ceeb, lithification yog txheej txheem ntawm kev puas tsuaj porosity los ntawm kev sib xyaw thiab cementation.
Yog li ntawd, dab tsi yog diagenesis thiab lithification?
Diagenesis , sum ntawm tag nrho cov txheej txheem, Chieflychemical, los ntawm cov kev hloov nyob rau hauv ib tug sediment yog coj txog tom qab nws deposition tab sis ua ntej nws kawg. lithification (kev hloov pauv rau pob zeb). Ib qho piv txwv ntawm mob ntshav qab zib yog cov tshuaj hloov pauv ntawm feldspar los tsim ib qho tshiab mineral hauv nws qhov chaw, av nplaum ntxhia.
Ob hom Lithification yog dab tsi?
Muaj ob lub ntsiab txoj kev uas lithification tshwm sim: compaction thiab cementation. Peb kuj tseem yuav kov ntawm peb txoj kev uas tseem ceeb rau qee cov sediments, hu ua recrystallization.

Lub luag haujlwm tag nrho ntawm cov tshuaj tiv thaiv lub teeb, thawj theem ntawm photosynthesis, yog hloov lub hnub ci zog rau hauv cov tshuaj siv hluav taws xob nyob rau hauv daim ntawv ntawm NADPH thiab ATP, uas yog siv nyob rau hauv lub teeb-yooj yim tshuaj tiv thaiv thiab roj sib sau ua ke ntawm qab zib molecules
Dab tsi yog cov txheej txheem uas tsim cov ntawv luam tshiab ntawm cov kab mob caj ces?
Cov txheej txheem ntawm DNA replication tsim ib daim qauv tshiab ntawm cov kab mob cov ntaub ntawv caj ces kom dhau mus rau lub cell tshiab. Dawb ntab nucleotides yog txuam nrog lawv cov lus qhuas los ntawm ib qho enzyme hu ua polymerase. Cov no yog 'lub tsev.' Lawv sib sau ua ke DNA tshiab strand nrog txhua tus qub strands

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
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
