Kev puas tsuaj yog txheej txheem ntawm yaig uas tshwm sim thaum cov khoom raug thauj mus los ntawm qhov chaw dhau sijhawm. Nws yog txheej txheem ntawm kev sib txhuam los ntawm scuffing, khawb, hnav, marring, thiab rub tawm ntawm cov khoom. Glaciation maj mam grinds pob zeb khaws los ntawm dej khov tiv thaiv pob zeb nto.
Tsis tas li ntawd, dab tsi yog abrasion nyob rau hauv weathering?
Pob zeb tawg mus rau hauv me me los ntawm huab cua . Pob zeb thiab sediment sib tsoo tawm tsam ib leeg hnav tawm qhov chaw. Hom no huab cua hu ua puas , thiab nws tshwm sim li cua thiab dej maj hla pob zeb. Cov pob zeb ua smoother li ntxhib thiab jagged npoo tawg.
Tom qab ntawd, lo lus nug yog, qhov piv txwv ntawm kev puas tsuaj yog dab tsi? The definition of ib puas yog thaj chaw uas mob, khawb los yog rub tawm. 1. Ib qho chaw ntawm ib sab caj npab uas yog khawb los ntawm kev poob ntawm lub tsheb kauj vab yog ib qho piv txwv ntawm ib puas . Ib cheeb tsam ntawm pob zeb ntawm ntug dej hiav txwv uas tau hnav tawm ntawm cov nthwv dej yog ib qho piv txwv ntawm ib puas.
Ib yam li ntawd, nws raug nug, qhov twg puas tshwm sim?
Pob zeb kev puas tsuaj tshwm sim feem ntau nyob rau hauv cov av nkos qhov twg cov pob zeb swb dhau ib leeg thaum huab hwm coj txav mus rau toj. Nws kuj tshwm sim nyob rau hauv lub hauv paus ntawm ib tug glacier qhov twg tej pob zeb uas yog khov rau hauv cov dej khov yog dragged nyob rau hauv qab lub glacier.
Ob hom kev puas tsuaj yog dab tsi?
Muaj ob feem ntau hom : ob - lub cev thiab peb lub cev puas . Ob - lub cev puas yog hais txog qhov chaw uas swb hla ib leeg qhov twg ib qho (nyuaj) cov khoom yuav khawb hauv thiab tshem tawm qee yam ntawm lwm yam (mos). Ib qho piv txwv ntawm ob - lub cev puas yog siv cov ntaub ntawv los tsim ib lub workpiece.

Ib tug eukaryote yog ib yam kab mob uas nws cov hlwb muaj ib tug nucleus nyob rau hauv ib daim nyias nyias. Eukaryotes sib txawv los ntawm cov kab mob ib leeg mus rau complex multicellular tsiaj thiab nroj tsuag. Qhov tseeb, feem ntau muaj sia nyob yog eukaryotes, ua los ntawm cov hlwb nrog cov nuclei thiab chromosomes uas muaj lawv cov DNA
Dab tsi yog qhov txawv ntawm kev siv science thiab natural science?
Natural sciences cuam tshuam nrog lub ntiaj teb lub cev thiab suav nrog astronomy, biology, chemistry, geology, thiab physics. Applied science yog cov txheej txheem ntawm kev siv cov kev paub txog kev tshawb fawb rau cov teeb meem, thiab siv rau hauv kev lag luam xws li engineering, kev saib xyuas kev noj qab haus huv, kev siv technology, thiab kev kawm thaum yau
Kev sib raug zoo ntawm science thiab social science yog dab tsi?
Kev tshawb fawb (tseem hu ua ntshiab, ntuj, lossis kev tshawb fawb lub cev) thiab kev tshawb fawb txog kev sib raug zoo yog ob hom kev tshawb fawb uas cuam tshuam nrog tib cov qauv kev tshawb fawb thiab cov khoom ntawm lawv tus kheej txoj cai lij choj. Kev tshawb fawb muaj kev txhawj xeeb ntau dua nrog kev kawm xwm, thaum kev tshawb fawb txog tib neeg kev coj cwj pwm thiab kev sib raug zoo
