Yog li ntawd, tag nrho cov South America yog them nrog av nplaum, ib tug multi-meter txheej.

Lub thickness ntawm humus yog me me txawm nyob rau hauv kev sib piv nrog lub Urals, qhov twg nws thickness ranges ntawm 15-20 cm mus rau ib nrab ib 'meter'. Cov ncej hloov uas ua rau cov av nkos yog ib txhij rau Urals thiab Asmeskas. Nyob rau hauv cov ntaub ntawv ntawm cov suab puam, cov lus piav qhia yog nyob rau saum npoo hlawv tawm los ntawm lub hnub. Txawm li cas los xij, ib cheeb tsam loj yog ua los ntawm thaj chaw saturated nrog noo noo. Tab sis tsis muaj humus.

Daim duab no tau tshwm sim hauv Yekaterinburg.

Nws qhia tau hais tias "kab lis kev cai" txheej, ib 'meter' tuab, ncav cuag lub cobbled pavement ntawm 1809 keeb kwm (humus raug tshem tawm mus rau xuab zeb los yog av nplaum thaum lub sij hawm kev tsim kho), thiab nyob rau hauv nws yog ib tug thiab ib nrab meter av nkos txheej. Vim li cas mudflow? - Ua tib zoo saib - muaj txheej tuab ntawm humus hauv qab nws. Kuv tsis muaj duav, tab sis nrog ib tug trowel tau los ntawm txhais tes ntawm ib tug neeg ua hauj lwm uas nws rov qab pom ntawm no, kuv tswj mus khawb ib lub qhov tob peb caug centimeters - lub humus mus ntxiv. Av nkos npog thaj tsam kawg ntawm lub xyoo pua 16th. Tsis ntev Yekaterinburg yug (1723).

Hauv South America, cov av sib txawv nrog cov tuab tuab yuav tsum tau tsim dua 400 xyoo. Tab sis, raws li peb tau pom, lawv yeej tsis muaj nyob. Vim li cas? Peb yuav xav thiab nrhiav cov lus teb.
