Ibunzi ilitye: impahla, ichazwa imbali

Omdala Imbali abantu kuhlangene kunye nophuhliso komlilo, ukufunda iimpawu izityalo kuluncedo kwaye ukufuywa kwezilwanyana. Kodwa inye kuphela into wamnika igama layo amaxesha zembali omkhulu ezimbini - Paleolithic kunye Neolithic. It is a banjengeqhwitha ngamatye. Mineral eyayibenza umntu ukuba abe ngukumkani wendalo.

Ukuba bagwetywe ngokwemiqathango mineralogy, Iqhwitha akukho nto ukhetheke: ibizwa phantse ngokupheleleyo yabhalwa ngezinto dust, umbala yandomeleza iityuwa zezinye iikhompawundi chemical. Ngenxa iyantlukwano kwezi zinto, kwaye kukho uluhlu olubanzi kweemeko ukubunjwa ilitye lenyengane kunokuba ifomu kunye nombala awayengayilindelanga.

Izazi ichaza ngokuthi "nzima unit ngokobunene" ifomu amorphous kunye cryptocrystalline of dust.

Eli litye ukhanye mncinane kakhulu, ukuba ujonga kuyo, ebeka phambi kumthombo wokukhanya onamandla. Amaxesha amaninzi ine- ngemvelaphi eziphilayo, ekubeni lesilicon yaba yinxalenye iqokobhe lembaza.

Kwizigidi zeminyaka yodaka kwi emazantsi kweelwandle yamandulo kuqala iguqulelwa yihakinto, uze emva koko kwezinye izimbiwa, kuquka yikalikedo. umbala wabo ezahlukahlukeneyo ukuze ngokukhawuleza eze engqondweni GEMS. Emangalisayo, Iqhwitha ilitye ngamanye amaxesha basebenzisa kule ndima, nangona yayo yahluke kakhulu.

Kudala-dala abantu baye baqaphela ukuba kuba lula olubengezela kakuhle, uze emva koko ihlolwe kwaye lukhuni yayo, ngenxa apho iiminerali waqalisa ukuba kusetyenziswa izinto zokwenza izixhobo kunye izitya. Emva koko abantu bafunda ukuba ba- ngokufanelekileyo kwaye cuba, ngoko ilitye lenyengane waba isixhobo loyikekayo, eziqulathwe iincam aziintshuntshe neentolo.

Ukuba ujonga benga yakhe ngemicroscope, ungabona iinaliti isuntswana iziponji yolwandle, amathambo radiolarian, igqabi incinane kakhulu ezincinane bivalves.

Formation of lesilicon unanamhla. Wave kunye nokurhoxa, umlambo kunye nemvula ngokuthe nibusile engxondorheni, zithwele uthuli ilitye batyunyuziweyo olwandle. Kwakhona bawe iikhemikhali baye eyafunyanwa phezu kobuso emva kuqhume. Ngokuthe ngcembe siyaphi zibe abahle dust colloidal kumiswa, leyo Axhome kwikholam emanzini. Inxalenye yale ukunqunyanyiswa isetyenziswa izilwanyana zaselwandle lenyama, imizimba ziyafuneka ukuze kwakhiwe shell. Ngokuthe ngcembe kwakhiwa ilitye lenyengane, le nkcazelo iye inikwe ngentla.

Khumbula indlela sathetha ngayo "viscosity 'umbandela? Uvunyelwe ukusebenzisa kuyo nokuveliswa kwezixhobo ilitye: cobblestones kwi hhayi ukuya iziqwenga, noqhekeko, oyinxalenye isitya ecocekileyo.

It luyasetyenzwa lenyengane wamnika umntu inzuzo nanto phezu izilwanyana zasendle. Ke kaloku ukukwazi yakhe zivulwe iintlantsi ugwayimbo impembelelo, ngoko ke abantu ivule kwihlabathi elitsha - ihlabathi nobushushu nomlilo kunye nokhuseleko. Ukutya yalungiswa ukuba okunencasa nokunesondlo, nakwezinye ezininzi ezinamandla babesoyika ubushushu amadangatye ukukhanya.

Siyathemba ukuba ndifunde indlela lomlilo elingunxantathu. indima yalo kwimbali impucuko yethu ayinakuphikiswa.
