Peb ntiaj chaw ntiaj teb muaj ntau yam minerals - pob zeb. Muaj ntau cov zaub mov no nyuaj. Xws li lub cev ntuj tuaj yeem tsim tau polyhedra - crystals.

Cov zaub mov seem yog kua. Cov no suav nrog mercury, dej, roj. Kuj tseem muaj roj. Cov no yog methane thiab carbon dioxide.

Igneous rocks

Nyob hauv lub ntiaj teb no muaj cov kua liab kub-magma. Nws muaj tag nrho cov khoom siv tshuaj, tshuaj tsis haum thiab dej vaporous.

Pouring sab nraud, magma maj mam txias thiab ua kom khov. Qhov no yog li cas pob zeb igneous tshwm.

Ntawm saum npoo lawv nrhiav tsis tau: lawv tau npog nrog lwm cov pob zeb thiab sediments.

Cov pob zeb tsis pom kev tseem hu ua crystalline, vim feem ntau ntawm lawv cov neeg sawv cev muaj cov qauv crystalline.

Nyob igneous rocks

Magma tuaj yeem nchuav rau hauv qhov tob ntawm lub ntiaj teb, thiab tej zaum ze rau saum npoo, thiab ncaj qha rau ntawm nws. Hom pob zeb igneous yuav nyob ntawm no.

Yog magma tawg tob tob hauv av(5-40 km), ces cov pob zeb no hu ua intrusive. Lawv cov neeg sawv cev nto moo tshaj plaws yog granite.

Cov pob zeb tsis sib haum - tuab, nrog cov qauv ua tiav crystalline.

Yog tias qhov tso tawm ntawm cov khoom tshwm sim rau saum npoo los yog ze rau nws (tsis tob tshaj 5 km), ces cov pob zeb tsim yog effusive. Cov no suav nrog bas alts, pumice, porphyry thiab lwm yam.

Bas alt: qhov tsos thiab cov khoom ntawm pob zeb

Bas alt tseem hu ua pob zeb hluav taws kub. Nws lub cev muaj zog xws li lub zog thiab qhov ntom ntom muaj txiaj ntsig zoo hauv kev lag luam.

Qee tus neeg kuj ntseeg txog nws cov khoom siv dag zog thiab muaj txiaj ntsig zoo rau lub cev.

Bas alt yog pob zeb effusive. Thaum lub roob hluav taws tawg, bas altic lava taug kev los ntawm cov kab nrib pleb hauv lub ntiaj teb crusts thiab erupts rau saum npoo. Ces nws txias thiab tig mus rau hauv lub pob zeb volcanic.

Bas alt yog xim dub lossis grey tsaus hauv cov xim, granular hauv cov qauv.

Muaj bas altic volcanoes, ua tsaug rau qhov uas muaj pob zeb effusive tshwm - bas alt. Ntawm lawv yog cov roob hluav taws hauv Kamchatka, Kuriles, thiab Vesuvius.

Qhov chaw yug ntawm bas alt yog Ethiopia. Nyob ntawd nws tau pom thawj zaug thiab txaus siab rau nws cov txiaj ntsig zoo. Lub pob zeb effusive no kuj tau txais nws lub npe los ntawm Ethiopia. Txhais los ntawm cov lus hauv zos, "bas alt" txhais tau tias "boiled".

Bas alt yog mined thoob plaws ntiaj teb: hauv Asmeskas, Canada, Russia, Is Nrias teb, South Africa thiab lwm lub tebchaws. Cov kws tshawb fawb ntseeg tias cov pob zeb loj heev ntawm volcanicpob zeb yog nyob rau hauv qab ntawm lub hiav txwv Pacific. Txawm li cas los xij, tsis tas yuav tsum tau mine nws hauv dej hiav txwv: hauv av, pob zeb no txaus.

siv tsev

Volcanic pob zeb yog siv rau lub hom phiaj hauv qab no:

rwb thaiv tsev ntawm tsev. Slabs yog tsim los ntawm bas alt, uas yog siv los insulate lub phab ntsa ntawm lub tsev. Ntawm cov txiaj ntsig - tsis muaj carcinogens, tsis ignite, tshem tawm condensate, ruaj. Ntawm cov minuses - tus nqi siab

  • Pem teb npog. Pem teb, facades ntawm tsev, qhov cub yog nteg tawm nrog pob zeb. Kev siv rau lub hom phiaj no muaj qhov tsis zoo: bas alt yog polished sai sai thiab pib plam.
  • Cov khoom siv ncaws pob npog. Skis, rackets, snowboards yog them nrog bas alt. Cov cuab yeej ua kis las tau txais lub zog thiab yoog raws, thaum muaj txheej txheej nyias.
  • ua cov hniav nyiaj hniav kub. Lub pob zeb tsis yog tshwj xeeb tshaj yog nrov hauv cov khoom siv tes ua khoom siv tes ua. Cov poj niam yuav nws nyoos los yog hauv daim ntawv hlaws, thiab ntau zaus tsuas yog vim nws cov khoom siv tshuaj. Cov txiv neej nyiam coj lub pob zeb los ua ib tug rosary.

Bas alt kuj tseem siv hauv asph alting, kev tsim kho thiab lwm yam haujlwm.

Kho thiab tej yam yees siv

Lub pob zeb roob hluav taws ntseeg tias muaj lub zog ua txuj ci tseem ceeb.

Qhov cuam tshuam ntawm bas alt rau txhua pawg neeg yog raws li hauv qab no:

  • Calms kev ntxhov siab, ntxhov siab, ntxhov siab ua ntej ib qho xwm txheej tseem ceeb.
  • Txhim kho lub hlwb ua haujlwm, qhib lub peev xwm hlwb.
  • Nyob zoo rau kev mloog, txhim kho kev xav.
  • Tiv thaiv los ntawm qhov tsis zoo tshwm sim(kev npam, kev npau taws, kev npau taws), ua kom tus tswv nyob hauv lub xeev muaj kev thaj yeeb.
  • Muab lub zog rau tib neeg, yog li txhim kho kev ua haujlwm.

Nws yog ib qho tseem ceeb rau tus poj niam hnav pob zeb thaum nws npaj cev xeeb tub lossis twb nqa menyuam. Kev sib txuas rau lub ntiaj teb yuav tsum tso cai rau bas alt los txhawb kev xeeb tub.

Cov tsiaj no kuj siv rau kev kho mob zaws, vim nws ua kom sov tau ntev. Cov pob zeb, polished rau cov duab ntawm lub pob, yog preheated rau 55 degrees Celsius. Cov txheej txheem no txo cov kab mob ntawm cov pob qij txha thiab cov hlab plawv.
