Npog-collapse sinkholes txhim kho heev ceev (qee zaum txawm nyob rau ib teev), thiab ua tau muaj kev puas tsuaj loj. Lawv tshwm sim qhov twg cov sediments npog muaj ib tug tseem ceeb npaum li cas ntawm av nplaum; Nyob rau tib lub sijhawm, qhov dej ntws tawm, yaig, thiab deposition ntawm sinkhole nyob rau hauv ib tug ntiav lub tais-zoo li kev nyuaj siab.
Hais txog qhov no, cov sinkholes tsim sai npaum li cas?
Ib lub voj voog feem ntau daim ntawv thiab loj hlob nyob rau ib lub sij hawm ntawm feeb mus rau teev. Slumping cov sediments nyob rau sab ntawm lub sinkhole tej zaum yuav siv li ib hnub lub sij hawm nres. Erosion ntawm ntug ntawm lub sinkhole tuaj yeem txuas ntxiv rau ob peb hnub, thiab cov dej nag hnyav tuaj yeem ua kom lub zog ruaj khov.
Ib yam li ntawd, cov sinkholes tshwm sim feem ntau qhov twg? Raws li USGS, kwv yees li 20 feem pua ntawm Teb Chaws Asmeskas cov av muaj kev cuam tshuam rau sinkholes . Cov feem ntau kev puas tsuaj los ntawm sinkholes nyiam tshwm sim hauv Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, thiab Pennsylvania. Daim duab qhia hauv qab no qhia txog thaj chaw uas cov kab noj hniav hauv av tuaj yeem tsim thiab puas tsuaj sinkholes ua tau tshwm sim.
Qhov sib thooj, cov cim ceeb toom ntawm lub dab dej yog dab tsi?
Nov yog 7 cov cim qhia pom tias lub dab dej tuaj yeem tshwm sim:
- Ib puag ncig kev nyuaj siab nyob rau hauv lub ntiaj teb:
- Localized subsidence los yog kev nyuaj siab nyob qhov twg ntawm cov cuab yeej:
- Lub pas dej ncig (los yog lub pas dej loj, tob):
- Lub hauv paus ntsiab lus:
- Kev tawg ntawm txoj kev lossis pavement:
- Tam sim ntawd poob ntawm qhov dej theem ntawm qhov chaw:
Cov av nyob ib ncig ntawm lub dab dej zoo li cas?
A sinkhole tuaj yeem nyob txhua qhov chaw ntawm kev nyuaj siab me ntsis hauv hauv av txoj cai mus txog ib lub qhov loj loj nce mus txog ib nrab ib kilometer. Lawv tsis muaj qhov dej ntws los ntawm ntuj, yog li cov dej uas nkag mus rau hauv ib qho sinkhole tsis tuaj yeem tawm ntawm qhov chaw - thiab yog li feem ntau ntws mus rau hauv qab, rau hauv cov txheej txheem subsurface.

Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Tus qauv yuav pab nrhiav qhov tshwm sim ntawm qhov kev tshwm sim sib xyaw li cas?
Lub ntsiab lus ntawm Qhov Muaj Peev Xwm Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej Txheej yog ib qho uas muaj ntau tshaj li qhov ua tau. Kev txiav txim siab qhov yuav tshwm sim ntawm qhov kev tshwm sim sib xyaw suav nrog kev nrhiav cov lej ntawm qhov tshwm sim ntawm tus kheej cov xwm txheej thiab, yog tias tsim nyog, tshem tawm qhov muaj feem sib tshooj
Qhov txheej twg yog huab cua tshwm sim feem ntau tshwm sim?
Troposphere. Lub troposphere (los ntawm Greek: tropein - hloov, ncig lossis sib xyaw) yog txheej qis tshaj plaws ntawm lub ntiaj teb huab cua. Feem ntau ntawm huab cua phenomena, systems, convection, turbulence thiab huab tshwm sim nyob rau hauv no txheej, tab sis tej zaum yuav mus rau hauv lub qis feem ntawm thestratosphere
Yuav ua li cas koj pom qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug?
Txhawm rau xam qhov tshwm sim ntawm qhov tshwm sim tshwm sim tsawg kawg ib zaug, nws yuav yog qhov sib ntxiv ntawm qhov xwm txheej tsis tshwm sim. Qhov no txhais tau hais tias qhov tshwm sim ntawm qhov tshwm sim yeej tsis tshwm sim thiab qhov tshwm sim ntawm qhov tshwm sim tsawg kawg ib zaug yuav sib npaug, lossis 100% txoj hauv kev
Puas yog Bacillus subtilis acid sai sai?
Rau kev sib piv, daim duab sab laug yog Bacillus subtilis, ib qho gram zoo, tsis yog-acid-ceev bacilli. smegmatis, ob qho tib si ntawm cov kua qaub-ceev tab sis qhia qhov tsis muaj zog gram cov tshuaj tiv thaiv
