Nzira yekuziva sei kana iri meteorite

Mameteorite ndiwo matombo makuru aya anokwanisa kupinda mumhepo yepasi achiguma awira pamusoro penyika. Zvisinei, patinowana dombo guru rine humwe unhu, zvakaoma kuziva sei kana iri meteorite kana dombo.

Nechikonzero ichi, isu tichakumikidza chinyorwa ichi kukuudza kuti ungaziva sei kana icho chawawana chiri meteorite kana kwete uye kuti hunhu hwayo uye mabviro ndeapi.

Nzira yekuziva sei kana iri meteorite

Zvidimbu zvemeteorite zvinowira pasi redu nguva dzose kubva kunze. Kazhinji vanowira mugungwa kana nzvimbo dzisina kushandiswa, saka hazvigoneke kuwana chidimbu cheasteroid pane imwe nzvimbo. Kana ukaona dombo mumunda zvinokufadza, unogona kushandisa mazano aya kuona kana chiri chinhu kunze kwenyika ino.

Magineti inokwezva ferromagnetic meteorite. Kana ikaswedera pedyo nemagineti uye ikasanamira, ingangove isiri ferromagnetic meteorite. Mameteorite chete anonamira kune magineti anonzi ferromagnetic.

Regmaglypts kuumba pamusoro pematombo matema kana shava. Anenge ose matombo matema ane ruvara rwakasvibira kupfuura matombo emazuva ose uye ane moldings pamusoro pawo. Kurema ndechimwe chinhu chakajairika. Dzinorema kwazvo, dzinorema pakati pe4 ne8 magiramu pa cubic centimita.

Kana iwe uchiri kusava nechokwadi, unogona kuputira dombo nemvura-based kana paste-based sandpaper. Meteorite anowanzoita sesimbi kana akakwenenzverwa. Kana imwe asteroid yawanikwa, inofanirwa kuenda kudhipatimendi re geology kuti iongororwe. Iwo maedzo anoona kana iyo asteroid ndiyo yainofanirwa kuve (yakasara yeasteroid yakadonha). Kana iyo asteroid ikapfuura 9 bvunzo dziri pamusoro, ichaonekwa seyechokwadi.

Pakati peMars neJupiter pane nzvimbo iyo vamwe vanotenda kuti kune nyika yakaparadzwa mukuumbwa kwesolar system. Mamirioni ematombo maduku nematombo anofungidzirwa kuti akaumba bhandi reasteroid, seri kwezvinofungidzirwa kuva mamiriyoni ezvidimbu zvemarara. Dzimwe nguva chimwe chezvimedu zveasteroid chinowira kunze kwekutenderera uye chinodhumhana nePasi.

Mamiriro ekudzidza maitiro ekuziva kana iri meteorite

fusion crust

Zvinhu zvakasviba zvakatenderedza meteorite, kana isina kutsemuka pakukanganisa, ndizvo zvinosiyanisa meteorite kubva kune zvimwe zvimedu zvatinogona kuwana. Ukobvu hwematombo ematombo ematombo anowanzo kukora kupfuura iwo emeteorite esimbi, asingadarike 1 mm mukobvu.

Makungu ematombo meteorites ane amorphous silica (mhando yegirazi) yakasanganiswa nemagnetite, iyo inobva kune silicates uye iron inoumba yakawanda stony meteorites.

Iyo yekunze dhizaini yesimbi meteorites inoumbwa nesimbi oxide inonzi magnetite, iyo inowanzova submillimeter. Vanowanzobatwa nezvinhu zvakasiyana-siyana zvemuchadenga, uye kana vakasiiwa kuti vagare pasi kwenguva yakareba vasina kuonekwa, vanotora chitarisiko chine ngura.

Shrinkage Fracture uye Oriental

Ndiwo maumbirwo atinoona muzvidimbu zvemamwe matombo ane matombo anoita kuti aite seakatsemuka. Zvinokonzerwa nekukurumidza kutonhora kwepasi, kutangira patembiricha yepamusoro-soro inokonzerwa nekukwesha kusvika kune yakaenzana tembiricha yemuchadenga, dzimwe nguva iri pasi pechando. Kutsemuka uku chinhu chakakosha pamamiriro ekunze anozotevera emameteorite.

Mameteorite ari muchadenga anogona kutenderera kana kuchengetedza kufamba kwemutsetse, uye paanenge achipfuura nepakati pemhepo anogona kungoerekana achinja kana kuramba achifamba kusvika asvika pasi. Aya ndiwo maitiro ako anogona kusiyana.

Meteorites anotenderera panguva yekudonha haazove neanofarira mamiriro ekunze uye saka anozove asina kujairika. Mameteorite asingatenderere achave nekutarisa kwakagadzikana panguva yekudonha, kugadzira koni ine mitsara yekukukurwa.

angular meteorites

Mamiriro ematombo ane matombo anoratidza aya makona, ari pakati pe80-90º, ane vertices yakatenderedzwa nemacheto. Ivo vanowanzopihwa ne polylines.

Regmaglyphs: iwo ma notches akagadzirwa pamusoro nenzira yakatenderera, conical mukudonha kwavo nekuda kwemaitiro emhepo. Metallic meteorites ndiyo inonyanya kuzivikanwa.

Mitsara yendege: Munguva yekudonha, nzvimbo ye meteorite inopisa kusvika pakupisa kwakanyanya, zvichiita kuti zvinhu zvinyunguduke uye zviite semvura. Panguva yekuputika kwemeteorite, kana ikarova, kupisa uye kunyunguduka kunomira kamwe kamwe. Madonhwe anotonhorera paganda, achigadzira mitsetse yekubhururuka. Mukuwedzera kune kuumbwa kwayo, chimiro chayo chinonyanya kusarudzwa nekutarisa kwayo uye kutenderera.

ruvara uye upfu

Kana meteorite iri nyowani, inowanzova yakasviba, uye fusion crusts yavo inogona kuratidza streamlines uye ruzivo runobatsira kuaziva. Mushure mekurara pasi kwenguva yakareba, meteorite inoshandura ruvara, iyo fusion crust inopera, uye zvinyorwa zvinopera. Simbi iri mumameteorites, senge iron iri mumidziyo, inogona kuve neoxidized nemamiriro ekunze.. Sezvo iyo ferrous metal inokonzera oxidize, inosvibisa matrix yemukati uye kunze kwedombo. Tanga nemavara matsvuku kana orenji mune dema dema rakanyunguduka. Nokufamba kwenguva, dombo rose rinoshanduka kuita ngura. Iyo fusion crust ichiri kuoneka, asi haisisiri dema.

Kana tikatora chidimbu ndokuchikwizira kumashure kwetairi, guruva raanoburitsa richatipa ruzivo: kana iri tsvuku, tinofungidzira meteorite, asi kana yakatsvuka, isu tiri kubata nehematite. Kana iri dema saka imagnetite.

Mamwe maitiro akajairika

Kunyangwe tichifunga nezvese hunhu uhu hunovasiyanisa kubva kune mamwe matombo akapoteredza, meteorites ane humwe hunhu hunofanirwa kutariswa:

• Iyo meteorite haina quartz
• Meteorite haana mavara akasimba kana akajeka, kazhinji ane dema kana shava nekuti akashandurwa neokisijeni.
• Mitsetse inooneka pane dzimwe meteorite inowanzochena uye haina ruvara.
• Iko hakuna mabhuru emhepo kana mhango mumameteorites, 95% yemameteorite anowanzo slag.
• Metallic meteorites uye metallic meteorites zvinokwezvwa zvakasimba kumagineti.

Ndinovimba kuti neruzivo urwu unogona kudzidza zvakawanda nezvekuziva sei kana chawawana chiri meteorite kana kwete.
