Qhov twg ntawm cov xwm txheej hauv qab no tso cai rau calcareous ooze pom hauv qab CCD? Yuav kom nws khaws cia saum CCD, ces muab nws npog ua ntej thauj mus rau qhov tob tob los ntawm hiav txwv pem teb kis.
Nyob rau hauv cov xwm txheej dab tsi koj xav kom pom qhov ntau tshaj plaws ntawm calcareous ooze nyob rau hauv qab dej hiav txwv?
CCD feem ntau pom nyob rau hauv qhov tob ntawm 4 - 4.5 km, txawm hais tias nws yog qhov ntiav ntau ntawm cov ncej uas cov dej ntws txias. Yog li calcareous oozes feem ntau yuav pom nyob rau hauv tropical lossis temperate waters tsawg dua li 4 km tob, xws li nyob rau nruab nrab ntawm dej hiav txwv ridge systems thiab atop seamounts thiab toj siab.
Nyob rau hauv qhov chaw twg koj yuav muaj feem yuav pom calcareous ooze deposited?
CCD feem ntau pom nyob rau hauv qhov tob ntawm 4 - 4.5 km, txawm hais tias nws yog qhov ntiav ntau ntawm cov ncej uas cov dej ntws txias. Yog li calcareous oozes feem ntau yuav pom nyob rau hauv tropical lossis temperate waters tsawg dua li 4 km tob, xws li nyob rau nruab nrab ntawm dej hiav txwv ridge systems thiab atop seamounts thiab toj siab.
Vim li cas calcareous ooze tshwm sim?
Calcareous ooze yog calcium carbonate av nkos tsim los ntawm qhov nyuaj (kev sim) ntawm lub cev ntawm cov kab mob dawb-floating. Thaum cov av nkos no tau tso lawm, nws tuaj yeem hloov mus rau hauv pob zeb los ntawm cov txheej txheem ntawm compaction, cementation, thiab recrystallization.
Yuav ua li cas yog qhov tsim nyog rau siliceous ooze kom sau rau ntawm ntug hiav txwv?
Yuav ua li cas yog qhov tsim nyog rau siliceous ooze kom khaws cia rau ntawm ntug hiav txwv? Cov dej saum npoo av yuav tsum muaj cov khoom noj muaj txiaj ntsig.

Lawv ceeb toom rau cov tswv dav hlau thiab cov tswv ntawm cov xwm txheej tsis zoo uas xav tau kev tshuaj xyuas tshwj xeeb, hloov pauv, lossis kho dua. Daim Ntawv Qhia Kev Pabcuam (S.B.) yog ib daim ntawv ceeb toom rau tus neeg tsav dav hlau los ntawm lub chaw tsim khoom qhia nws txog kev txhim kho cov khoom .
Nyob rau hauv tus txheej txheem desalination twg ntawm cov hauv qab no yog tshem tawm ntawm dej?
Desalination yog ib txheej txheem uas tshem tawm ntsev ntau dhau thiab lwm yam minerals tawm ntawm dej. Nyob rau hauv feem ntau cov txheej txheem desalination, pub dej yog kho thiab ob kwj dej yog tsim: kho cov dej tshiab uas muaj tsawg concentrations ntawm ntsev thiab minerals .
Nyob rau hauv qhov xwm txheej twg nws raug cai rau tus menyuam yaus muaj cawv?

Calcareous ooze tshwm sim nyob qhov twg?
Calcareous ooze dominates dej hiav txwv sediments. Cov kab mob uas muaj calcium-raws li cov plhaub xws li foraminifera muaj ntau thiab nthuav dav thoob plaws ntiaj teb cov dej hiav txwv bass - ntau dua li cov kab mob silica . calcareous ooze feem ntau yuav pom nyob qhov twg?
Calcareous ooze thiab siliceous ooze txawv li cas?
Siliceous ooze yog ib hom biogenic pelagic sediment nyob rau hauv dej hiav txwv tob. … Siliceous oozes yog tsim los ntawm cov pob txha ua los ntawm opal silica Si(O 2), as opposed to calcareous oozes, uas yog tsim los ntawm skeletons ntawm calcium carbonate kab mob (piv txwv li coccolithophores).
