Kusiyana pakati kwemiviri yokudenga

The meteor rakasiyana meteorite? Mubvunzo uyu refu yakaramba isingazivikanwi kusvikira vanoongorora nyeredzi, chikonzero pakuongorora uye kutsvakurudza.

Kupfuta pashure nechisimba pasi muchadenga vasava uremu. Asati ava vakawanda combustion zvomuchadenga chinhu hazvirevi kupfuudza magiramu gumi. ukoshi Izvi vasingakoshi saka zvichienzaniswa ukuru Earth, kubvira pakupunzika munhu meteor hapana zvichaitika.

Meteorites akawira pasi redu, kuchikosha uremu. KuChelyabinsk meteorite yakawira pamusoro pemvura February 15, 2013, maererano nyanzvi nokufungidzira, rairema anenge gumi matani.

The dhayamita yokudenga muviri waiva 17 m, kuti velocity vakapfuura 18 km / s. KuChelyabinsk meteorite akatanga putika panguva yakakwirira makiromita anenge makumi maviri, uye zvachose ya ndege haina kupfuudza mumasekonzi makumi mana. simba nokuputika matatu nguva kupfuura kubhomba pakati Hiroshima, dzakaumbwa somugumisiro vakawanda zvidimbu uye zvimedu akawira kuChelyabinsk pasi. Saka nharo kuti meteor akasiyana meteorite, pakutanga kwezvose, tinoona dzavo uremu.

Kudeuka meteorite yaiva chinhu dzakaonekwa pakutanga ramakumi remakore vokuNamibia. Rairema matani makumi matanhatu.

Frequency donhwe

The meteor rakasiyana meteorite? Tinoramba kutaura kusiyana mitumbi yokudenga izvi. Mumhepo panyika imwe chete zuva ikoko kuvheneka mazana emamiriyoni kupfuta. Kana pachena okunze unogona kutarisa inenge awa 5-10 "kupfura nyeredzi" dziri chaizvoizvo kupfuta.

Meteorites vari kazhinji vanozviwana pamusoro redu, asi vakawanda vavo vanopisira kunyange panguva rwendo. Nokuti zuva ikaitika panyika mashomanana zana mitumbi yokudenga yakadaro. Nokuti vakawanda vavo yacho murenje, makungwa, nyanza, havasi kuratidza vaongorori. Masayendisiti nokuti gore zvinogoneka kudzidza chete vashoma mitumbi izvi yokudenga (zvidimbu mashanu). Achipindura mubvunzo pamusoro kweinozivikanwa mune kupfuta uye meteorites, tinogona kuona sezvamunoita yavo.

unogumburwa

nezvimedu Small anoumba meteoroid vanokwanisa kukonzera kukuvara zvakanyanya. Hunozoita Worn pemvura chitundumusere-musere, anogona chokukuvadza basa simba ravo hurongwa.

Zvakaoma rokuongorora chaiyo ngozi meteorites. Pamusoro pemvura pashure kuitika anoramba guru mari "scarring" uye "kuporesa". Kana muviri yokudenga zvakadaro guru, zvino paricharova Earth akabatana zvaizopedza zvinogoneka kuti inokanganisa okunze.

Kuti kunyatsonzwisisa kwakakura dambudziko, unogona kupa muenzaniso Tunguska meteorite. Akawira kudondo, zvichiita zvakakomba kuvadza nzvimbo zviuru zvakawanda mativi makiromita. Kana nzvimbo yaigarwa nevanhu, zvinogona kunge nehurukuro pamusoro njodzi chaiyo.

Meteor ari chiedza chakajairika inowanzotaurwa kuchengetwa denga rizere nenyeredzi. Rinoshandurwa kubva pane rechiGiriki rinoreva "hwokudenga." Meteorite muviri yakasimba kuva nzvimbo mavambo. In Russian shanduro iri izwi rinonzwika se "ibwe kubva kudenga."

kwesainzi

Kuti tinzwisise kuti comets uye meteorites vakasiyana kupfuta, ongorora migumisiro kwesainzi. Vanodzidza nezvenyeredzi vaigona kuwana kuti mushure meteor yarova Dzenyika mhepo akaturikidzana ndiyo kwepfumo yavo. Muna combustion muitiro anoramba zodzera, zvinosanganisira ionized gasi. Meteor nezvimedu anowa panguva nekukwirira makumi manomwe chete kubva pepasi. The kometi anosiya azere nyeredzi "muswe." Its chinoita chinoumba, izvo zvinosanganisira huruva uye chando. Uyezve, zvinotevera zvinhu zvinogona riri kometi: carbon dioxide, amoniya, makemikari tsvina. Guruva muswe, izvo kunosiya kwayo zvitange chinoumbwa gaseous inoramba.

Kamwe muna Wepasi rokumusoro mhepo, mitumbi nzvimbo dzakaparadzwa zvimedu kana seguruva vanotsamwira ne kukweshera ikabuda. Vashoma vavo pakarepo ndipiswe, uye makuru, vakaramba kuwa kuchengetera ari luminous kutevera ionized gasi. Ivo akadzimwa, richisvika kure anenge akaenzana makumi manomwe chete kubva pasi pevhu.

Flash nguva pakutsvaga gobvu ari zvomuchadenga muviri. Kana guru combustion meteor vanogona kunakidzwa inopenya kupenya maminitsi akawanda. Izvi vanodzidza nezvenyeredzi kudana mvura nyeredzi. Kana munhu meteor yokugezera neawa rimwe unogona kuona anenge zana kupfuta kutsva. Kana zvomuchadenga muviri hombe hukuru mubishi kutamira kuburikidza rizere Earth muchadenga, hazvina kuparadzwa uye kunosvika pechiso nyika. Earth asati chinosvika hapana anopfuura gumi muzana yepakutanga kurema meteorite.

Sezvo chikamu simbi meteorites ane chinokosha yakawanda nickel nedare. Hwaro ibwe kwemiviri yokudenga ndivo silicates: olivine uye pyroxene. muviri Iron-ibwe ane zvinenge zvakaenzana uwandu silicates nesimbi-nickel.

mhedziso

Vanhu nguva dzose ivepo, akaedza kudzidza miviri yokudenga. Star makarenda vakanga vakatsunga mamiriro ekunze, achiedza kufanotaura zvaitika akasangana kutya azere nyeredzi.

Pashure kuonekwa rakasiyana-siyana materesikopu, vanoongorora nyeredzi vakakwanisa kukanganisika zvakawanda zvakavanzika uye zvakavanzika azere nyeredzi. Zvave zvikuru kudzidza comets, kupfuta, meteorites, zvinokosha zvakasiyana uye zvakafanana pakati mitumbi yokudenga izvi. Somuenzaniso, chikuru meteorite, kurova pamusoro panyika, aiva simbi Goba. Masayendisiti Its vakaona ari wechiduku America, pakurema kwayo kwakanga pamusoro matanhatu matani. Best aizivikanwa zuva nenyika dzinotenderera pariri anonzi Halley kuti kometi. Zvinonzi chokuita kuwanikwa nomurayiro regiravhiti.
