Cov terrigenous deposits yog cov uas pom nyob rau hauv lub continental rhawv thiab slopes thiab feem ntau muaj cov pob zeb khoom muab los ntawm kev hnav thiab tsim kua muag. Lub pelagic tso nyiaj yog cov uas pom nyob rau ntawm ntug hiav txwv tob thiab qhov tob. Cov no tso nyiaj Feem ntau muaj cov organic seem ntawm cov nroj tsuag thiab tsiaj txhu.
Yog li ntawd, dab tsi yog pelagic deposits?
Kev txhais ntawm pelagic deposits .: sedimentary tso nyiaj nyob rau hauv lub abyssal qhov chaw ntawm dej hiav txwv muaj ntau ntawm cov seem ntawm pelagic kab mob, volcanic plua plav, thiab meteoritic hais.
Tsis tas li ntawd, nyob qhov twg yog cov av nkos terrigenous pom? Terrigenous sediment , dej hiav txwv tob sediment thauj mus rau dej hiav txwv los ntawm cov dej ntws thiab cua los ntawm cov av. Zoo heev sediments uas ncav cuag lub txee continental feem ntau khaws cia rau hauv submarine canyons nyob rau sab av loj. Turbidity tam sim no nqa cov no sediments nqes mus rau hauv hiav txwv tob.
Kuj tseem paub yog, dab tsi yog lub hauv paus tseem ceeb ntawm cov sediments terrigenous?
Qhov chaw ntawm terrigenous sediments suav nrog volcanoes, huab cua ntawm pob zeb, cua-tshuab plua plav, sib tsoo los ntawm glaciers, thiab sediment nqa los ntawm icebergs.
Qhov twg thickest deposits ntawm terrigenous sediment feem ntau tsim?
Cov tuab tshaj accumulations ntawm sediments hauv ntiaj teb no yog nyob hauv dej hiav txwv. Tag nrho tab sis 8% ntawm lub ntiaj teb sediment yog nyob rau hauv dej hiav txwv nyob rau hauv pawg mus txog 9 km tuab . Cov tuab tshaj khaws cia yog nyob rau continental slopes thiab nce.

Ib feem ntawm sociobiology cuam tshuam nrog kev coj tus cwj pwm tsis zoo feem ntau. Cov neeg thuam tau hais tias daim ntawv thov ntawm sociobiology no yog ib hom kev txiav txim siab caj ces thiab nws ua tsis tau raws li qhov nyuaj ntawm tib neeg tus cwj pwm thiab qhov cuam tshuam ntawm ib puag ncig ntawm tib neeg txoj kev loj hlob
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim

Halite feem ntau yog cov pob zeb hauv av uas feem ntau tsim hauv cov huab cua qhuav uas dej hiav txwv evaporates. Nyob rau lub sij hawm geological, ntau cov ntsev deposits loj heev tau tsim thaum rov ua dua ntawm cov dej hiav txwv evaporation tshwm sim nyob rau hauv txwv bass. Ib txhia ntawm cov deposits yog ntau txhiab ko taw tuab
Ib qho piv txwv ntawm terrigenous sediment yog dab tsi?
Terrigenous sediment. Qhov chaw ntawm cov av qeeg muaj xws li cov roob hluav taws, huab cua ntawm cov pob zeb, cov plua plav cua tshuab, sib tsoo los ntawm cov dej khov, thiab cov dej ntws los ntawm cov dej ntws los yog cov dej khov
