Feem ntau cov zaub mov tuaj yeem ua tus cwj pwm thiab cais los ntawm lawv lub cev tshwj xeeb: hardness, luster, xim, strrea Feem ntau cov zaub mov tuaj yeem ua tus yam ntxwv thiab cais los ntawm lawv lub cev tshwj xeeb: hardness, luster, xim, streak, tshwj xeeb gravity, cleavage, tawg, thiab tenacity..
Ntawm no, cov kws tshawb fawb faib cov pob zeb li cas?
Cov kws tshawb fawb feem ntau cais cov pob zeb los ntawm lawv li cas los yog tsim. Muaj peb hom loj ntawm pob zeb : Metamorphic, Igneous, thiab Sedimentary. Metamorphic Pob zeb - Metamorphic pob zeb yog tsim los ntawm qhov kub thiab txias. Thaum lub volcano erupts, nws spews tawm kub molten pob zeb hu ua magma los yog lava.
Tsis tas li ntawd, cov yam ntxwv ntawm txhua hom pob zeb yog dab tsi?
| Pob zeb hom | Observable yam ntxwv |
|---|---|
| Clastic | Ua los ntawm cov pob zeb me me cemented ua ke. Qee zaum muaj fossils. Feem ntau muaj txheej txheej. |
| Tshuaj | Feem ntau lub teeb grey, qee zaum nrog cov muaju, qee zaum nrog cov plhaub, qee zaum tsuas yog loj. |
| 3. Metamorphic | |
| Feem ntau muaj interlocking crystals thiab txheej (hu ua foliation) |
Hais txog qhov no, cov khoom dab tsi tuaj yeem siv los faib cov pob zeb?
Cov khoom hauv qab no muaj txiaj ntsig zoo rau kev txheeb xyuas lub hom phiaj:
- Hardness.
- Cleavage.
- Luster.
- Xim.
- Streak pob zeb hmoov.
- Kev ntxhib los mos.
3 hom pob zeb tau faib li cas?
Peb lub ntsiab hom , los yog chav kawm, ntawm pob zeb yog sedimentary, metamorphic, thiab igneous thiab qhov sib txawv ntawm lawv yuav tsum ua li cas lawv tsim. Sedimentary pob zeb yog tsim los ntawm cov xuab zeb, plhaub, pebbles, thiab lwm yam khoom tawg.

Dab tsi yog ob yam cuab yeej uas cov kws tshawb fawb siv thaum ntxuav cov pob txha?
Yog li cov kws tshawb fawb siv bulldozers los khawb cov pob zeb thiab av. 2. Cov neeg ua hauj lwm ces siv duav, xyaum, rauj, thiab chisels kom cov pob txha tawm hauv av
Dab tsi yog cov kws tshawb fawb taxa siv los faib cov khoom muaj sia?
Kev tshawb fawb ntawm kev faib cov tsiaj muaj sia hu ua taxonomy. Linnaeus tau qhia txog cov txheej txheem kev faib tawm uas tsim los ntawm kev faib tawm niaj hnub no. Taxa hauv Linnaean system suav nrog lub nceeg vaj, phylum, chav kawm, kev txiav txim, tsev neeg, genus, thiab hom
Cov cuab yeej dab tsi uas tus kws tshawb fawb marine siv?
Qee cov cuab yeej siv los kawm txog biology ntawm cov kab mob hauv hiav txwv muaj xws li cov cuab yeej siv xws li plankton nets thiab trawls, cov khoom siv hauv qab dej xws li lub koob yees duab yees duab, tsheb khiav deb, hydrophones thiab sonar, thiab kev taug qab txoj hauv kev xws li satellite cim npe thiab kev tshawb fawb yees duab
Dab tsi yog cov cuab yeej lossis cov ntaub ntawv uas tus Kws Tshawb Fawb xav tau los txheeb xyuas cov ntaub ntawv nug?
Cov ntaub ntawv raug nug hauv chav kuaj ua txhaum cai yog nruab nrog lub tshuab ntsuas ntsuas, ntsuas cov duab digital, infrared thiab ultraviolet lub teeb ci, cov cuab yeej tshuaj ntsuam video thiab cov cuab yeej tshwj xeeb suav nrog cov khoom siv hluav taws xob tshawb pom electrostatic (EDD) thiab cov khoom siv los ua chemistry
Cov txheej txheem dab tsi uas tus kws tshawb fawb siv los tsim ntau cov ntawv luam ntawm DNA xav tau sau rau hauv daim ntawv dawb paug 1?
Molecular Cloning. Cloning tso cai rau tsim ntau cov ntawv luam ntawm cov noob, qhia cov noob, thiab kawm txog cov noob tshwj xeeb. Yuav kom tau txais cov DNA tawg rau hauv cov kab mob hauv cov kab mob hauv daim ntawv uas yuav tau theej lossis nthuav tawm, cov khoom tawg yog thawj zaug tso rau hauv plasmid
