Thaum twg cov sediments yog cemented los yog compacted ua ke?
Anonim

txheej txheem no hu ua compaction. Nyob rau tib lub sij hawm cov khoom ntawm sediment pib lo rau ib leeg - lawv yog cemented ua ke los ntawm av nplaum, los yog cov minerals xws li silica los yog calcite. Tom qab compaction thiab cementation cov sedimentary sequence tau hloov mus rau hauv cov pob zeb sedimentary.

Yuav ua li cas thaum sediment yog cemented?

Compaction thiab cementation ua rau lithification ntawm sedimentary pob zeb. Sediments yog compacted los ntawm qhov hnyav ntawm pob zeb thiab sediments saum lawv. Sediments yog cemented los ntawm dej uas khi sediments ua ke. Minerals precipitate ua pob zeb sedimentary.

Thaum cov sediments tau ntim thiab cemented ua ke hom pob zeb tsim?

14) pob zeb sedimentary cov ntaub ntawv thaum cov sediments tau cog lus thiab cemented ua ke, thaum cov zaub mov tsim los ntawm cov kev daws teeb meem, lossis thaum dej evaporates tawm cov pob zeb qab. Cov pob zeb hauv cov pob zeb sedimentary feem ntau tuav ua ke nrog cov cements ntuj. Piv txwv ntawm cov pob zeb sedimentary muaj xws li sandstone, limestone, thiab pob zeb ntsev.

Dab tsi ua rau cov av nplaum sib xyaw ua ke?

Thaum cov pob zeb sediments tso, nce hauv qhov hnyavua rau lub siab nce ntxiv uas ua rau cov pob zeb sib sau ua ke. Cov dej raug thawb tawm thiab cementation tshwm sim raws li cov pob zeb hauv av tau tso rau hauv qhov chaw me me ntawm cov pob zeb sediments ua cov kua nplaum uas khicov sediments ua ke.

5 kauj ruam ntawm lub pob zeb yog dab tsi?

Raws li lava txias nws hardens thiab dhau los ua pob zeb tsis zoo. Sai li cov pob zeb tsis muaj zog tshiab tau tsim, cov txheej txheem ntawm huab cua thiab yaig pib, pib tag nrho lub voj voog ib zaug ntxiv!

Thaum cov khoom nqa mus rau lwm qhov, nws yog hu ua erosion.
