Kames yog mounds ntawm sediment uas tso rau pem hauv ntej ntawm ib tug maj mam yaj los yog nyob twj ywm glacier / daim ntawv dej khov. Cov sediment muaj cov xuab zeb thiab gravels, thiab tsim mus rau hauv mounds thaum cov dej khov yaj thiab ntau cov sediment tso rau saum cov khib nyiab qub.
Tom qab ntawd, ib tus tuaj yeem nug, Esker yog dab tsi thiab nws tsim li cas?
Feem ntau cov eskers yog tsim nyob rau hauv cov dej khov-walled qhov los ntawm cov kwj uas ntws hauv qab thiab hauv glaciers. Thaum cov phab ntsa dej khov yaj ploj mus, cov dej deposits tseem nyob li winding ridges. Eskers tuaj yeem yog tsim saum toj no lub glacier los ntawm tsub zuj zuj ntawm sediments nyob rau hauv supraglacial channels.
Tom qab ntawd, lo lus nug yog, Kame Terrace yog dab tsi? Kame terrace . Txhais: lub tiaj-topped mound los yog toj uas muaj cov xuab zeb thiab gravel tso los ntawm meltwater nyob rau hauv lub qub glacial pas dej. Kame terraces daim ntawv thaum sediment accumulates nyob rau hauv lub pas dej thiab pas dej dai ntawm lobes ntawm glacier ice los yog ntawm ib tug glacier thiab lub hav.
Ib sab ntawm qhov no, qhov txawv ntawm Esker thiab Kame yog dab tsi?
Nco ntsoov tias cov no sib txawv tsis cuam tshuam rau cov txheej txheem ntawm huab cua tom qab niam txiv cov khoom tso tawm (piv txwv li, lawv tsis yog pedogenic). Kame : ib tug mound-zoo li toj ntawm ice-contact stratified drift. Esker : ib tug ntev nqaim ice-contact ridge. Eskers feem ntau yog sinuous thiab muaj li ntawm stratified drift.
Yuav ua li cas eskers thiab drumlins tsim?
Eskers thiab Drumlins yog nta tsim los ntawm kev ua glacial. ntws, carved rau hauv lub hauv paus ntawm glacial ice. lawv mus tshaj deposited moraines, lawv daim ntawv cov tshiab, thiab tuaj yeem hloov kho rau hauv drumlins . Drumlins yog hills uas streamlined thiab muaj mus txog.

Dab tsi yog daim ntawv cog lus ionic thiab nws tsim li cas?
Ionic daim ntawv cog lus, tseem hu ua electrovalent bond, hom kev sib txuas tsim los ntawm electrostatic attraction ntawm oppositely them ions nyob rau hauv ib tug tshuaj compound. Xws li daim ntawv cog lus thaum lub valence (sab nrauv) electrons ntawm ib lub atom raug xa mus tas li mus rau lwm lub atom
Photochemical smog yog dab tsi thiab nws tsim li cas?
Photochemical smog yog ib qho kev sib xyaw ntawm cov pa phem uas tsim los thaum nitrogen oxides thiab volatile organic compounds (VOCs) hnov mob rau hnub ci, tsim kom muaj huab cua daj cua dub saum cov nroog. Nws feem ntau tshwm sim nyob rau lub caij ntuj sov, vim hais tias yog thaum peb muaj hnub ci tshaj plaws. Cov pa phem thawj
Dab tsi yog DNA zoo li cuam tshuam nws cov qauv tshuaj rau nws zoo li cas thaum muaj ntau ntawm nws yog clumped ua ke?
Hais txog nws cov qauv tshuaj rau nws zoo li cas thaum ntau nws yog clumped ua ke. DNA zoo li kab laug sab webs. DNA tau soluble hauv DNA extraction tsis yog li peb tsis pom nws. Thaum nws tau stirred rau hauv ethanol, nws clumped ua ke thiab tsim thicker thiab thicker strands loj txaus kom pom
Dab tsi yog ib qho dot thiab kab kos duab thiab nws tsim li cas?
Dot thiab cross diagrams Cov electrons los ntawm ib lub atom yog qhia raws li cov dots, thiab cov electrons los ntawm lwm lub atom yog qhia raws li crosses. Piv txwv li, thaum sodium reacts nrog chlorine, electrons hloov ntawm sodium atoms mus rau chlorine atoms. Daim duab qhia ob txoj hauv kev los sawv cev rau qhov kev hloov hluav taws xob no
Dab tsi yog tus duab ntxoov ntxoo thiab nws tsim li cas?
Duab ntxoov ntxoo yog tsim los ntawm thaiv lub teeb. Lightraystravel los ntawm qhov chaw hauv kab ncaj nraim. Yog hais tias ib qho opaque (khoom) khoom nyob rau hauv txoj kev, nws nres lub teeb rays los ntawm kev mus los.Qhov no tshwm sim nyob rau hauv ib cheeb tsam ntawm qhov tsaus ntuj tshwm sim tom qab cov khoom
