Sedimentary pob zeb tuaj yeem yog koom ua ob pawg. Thawj yog detrital pob zeb , uas yog los ntawm erosion thiab tsub zuj zuj ntawm pob zeb tawg tawg, sediment , los yog lwm yam ntaub ntawv-categorized nyob rau hauv tag nrho raws li detritus, los yog khib nyiab. Lwm qhov yog tshuaj pob zeb , ua los ntawm kev sib cais thiab nag lossis daus ntawm cov zaub mov.
Ib yam li ntawd, cov pob zeb sedimentary tsim cov lus teb luv luv li cas?
Sedimentary pob zeb yog tsim Thaum cov av tso tawm ntawm huab cua, dej khov, cua, lub ntiajteb txawj nqus, lossis dej ntws nqa cov khoom hauv kev ncua. Qhov no sediment yog feem ntau tsim thaum huab cua thiab yaig tawg a pob zeb mus rau hauv cov khoom xoob hauv qhov chaw.
Tsis tas li ntawd, cov pob zeb sedimentary li cas tso? Sedimentary pob zeb daim ntawv thaum tshiab sediments yog tso nyiaj nyob saum cov laus pob zeb . Raws li ntau sediment ntxiv, nws yog compressed thiab hardens rau hauv pob zeb txheej . Txoj cai ntawm superposition yog lub hauv paus ntsiab lus uas hais tias yau pob zeb dag saum laus pob zeb yog tias txheej tsis tau muaj kev ntxhov siab.
Ntawm no, cov pob zeb sedimentary tsim ib kauj ruam li cas?
Tsim ntawm Sedimentary pob zeb Sedimentary pob zeb yog cov khoom ntawm 1) weathering ntawm preexisting pob zeb , 2) kev thauj cov khoom huab cua, 3) tso cov khoom, ua raws li los ntawm 4) compaction, thiab 5) cementation ntawm sediment rau daim ntawv ib pob zeb . Ob tug tom qab cov kauj ruam hu ua lithification.
Dab tsi yog 3 txoj kev sedimentary pob zeb tuaj yeem tsim tau?
Sedimentary pob zeb, uas yog tsim los ntawm sediments ntawm lwm cov pob zeb thiab cov ntaub ntawv, tsim los ntawm ntau txoj kev. Cov txheej txheem no suav nrog yas sedimentation, chemical sedimentation thiab biochemical sedimentation.
