Raws li sediment yog thauj los ntawm tam sim no ntawm huab cua los yog dej, lub sediment cais raws li rau qhov loj. Qhov no hu ua kev xaiv . Raws li cov dej los ntawm cov kwj deg sib xyaw nrog cov dej hauv lub pas dej, nws qhov nrawm nrawm nrawm nrawm. Thaum qhov no tshwm sim, cov nplej loj ntawm sediment ua hnyav dhau rau tam sim no rau txav.
Tsis tas li ntawd, cov sediments tau txheeb li cas?
Kev txheeb piav qhia txog kev faib ntawm grain loj ntawm sediments , nyob rau hauv unconsolidated deposits los yog nyob rau hauv sedimentary pob zeb. Qhov no yuav tsum tsis txhob tsis meej pem nrog crystallite loj, uas yog hais txog tus kheej qhov loj ntawm cov siv lead ua hauv cov khoom. Zoo txheeb pob zeb feem ntau yog ntxeem tau, thaum tsis zoo txheeb pob zeb muaj tsawg porosity.
Tom qab ntawd, lo lus nug yog, dab tsi txiav txim siab sorting hauv puam sediments? Cua, nthwv dej, thiab dej ntws tas li txav mus thiab rov faib cov ntug hiav txwv sediments raws ntug dej hiav txwv. Puam sediments uas tau thauj mus deb heev yuav txheeb raws li grain loj. Winnowing ntawm ntau uniform sediment cov duab thiab qhov loj me ua rau a puam nrog zoo- sorted sediments.
Ua raws li qhov no hauv kev txiav txim siab, dab tsi yuav ua rau sediments tsis zoo?
Piav li cas sediments ua txheeb . Dab tsi yuav ua rau sediments tsis zoo ? Glacial txog, muaj cov sib tov ntawm ntxhib pob zeb tawg, xuab zeb, silt, thiab av nplaum, tau tso los ntawm kev ua haujlwm qeeb qeeb ntawm daim ntawv dej khov, thiab yog ib qho piv txwv zoo ntawm lub kaum sab xis, tsis zoo - sorted sediment.
Yuav ua li cas sediments ua sedimentary pob zeb?
Rau sediment rau ua pob zeb sedimentary , nws feem ntau yog faus, compaction, thiab cementation. Clastic sedimentary pob zeb yog qhov tshwm sim ntawm huab cua thiab yaig ntawm qhov chaw pob zeb , uas hloov lawv mus rau hauv pieces-clasts-of pob zeb thiab minerals. Lawv feem ntau yog thauj los ntawm dej thiab tso rau hauv cov khaubncaws sab nraud povtseg sediment.

Yuav ua li cas koj txiav txim siab npaum li cas ntawm cov kua qaub uas yuav tsum tau neutralize lub hauv paus?
Kev daws qhov teeb meem Acid-Base Neutralization Kauj Ruam 1: Muab xam cov moles ntawm OH-. Molarity = moles / ntim. moles = Molarity x Volume. moles OH- = 0.02 M/100 milliliters. Kauj ruam 2: Xam qhov ntim ntawm HCl xav tau. Molarity = moles / ntim. Volume = moles/molarity. Volume = moles H+/0.075 Molarity
Peb hom sediments yog dab tsi?
Muaj peb hom sediment, thiab yog li ntawd, sedimentary pob zeb: clastic, biogenic, thiab tshuaj, thiab peb sib txawv ntawm peb raws li cov fragments uas tuaj ua ke los tsim lawv. Cia peb saib thawj hom hais, uas yog clastic. Clastic sediments yog tsim los ntawm cov pob zeb tawg
Yuav ua li cas yog cov structural units uas ua ionic compounds thiab yuav ua li cas lawv hu ua?
Rau binary ionic compounds (ionic compounds uas muaj tsuas yog ob hom ntawm cov ntsiab lus), cov tebchaw muaj npe los ntawm kev sau lub npe ntawm cov cation ua ntej tom qab lub npe ntawm anion. Piv txwv li, KCl, ib qho ionic compound uas muaj K + thiab Cl-ions, yog lub npe hu ua potassium chloride
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Seafloor sediments yog dab tsi?
Dej hiav txwv Floor Sediments. Muaj peb hom dej hiav txwv pem teb: terrigenous, pelagic, thiab hydrogenous. Terrigenous sediment yog muab los ntawm thaj av thiab feem ntau tso rau ntawm cov txee sab av loj, sab av loj nce, thiab qhov tob tob tob. Nws yog ntxiv contoured los ntawm muaj zog tam sim no nyob rau hauv lub continental nce
