Naasohoodu wuxuu ka yimid xagga meteorite ka duwan? Description, tusaalooyin meteors iyo meteorites

Ka hadal waxa ka meteorite Meteor kala duwan in aad ogaato wax qarsoon oo aqonsado samada samada. Stars dadka ku kalsoon hawadooda aan aadka u jecelnahay, laakiin waxaan diirada saari doontaa hay'adaha kale ee samadu.

Features naasohoodu

Ereyga "naasohoodu" waxa uu la xidhiidhaa ifafaale ka dhacda jawiga, waxaa taas oo heerka weyn duuleen meydadka shisheeye. qayb ka yihiin u yar yar oo ay u halligmaan degdeg ah dhacdaa ka yar tallaabada of khilaaf.

Ha u hesho in ay meteors dusha sare? Description oo ka mid ah jidhadhka samada, soo jeediyay by cirbixiyeyaasha, waxaa ku koobnayn ay calaamad u yihiin muddo gaaban oo xariijimo iska Ifto Yuuna iftiinka cirka ka samada. Seynisyahanno iyaga ugu yeedho "xiddigaha toogashada."

Astaamaha u gaarka ah meteorites

meteorite waa hadhaagii meteoroid ah in uu gaaro dusha sare ee dhulkeenna. Iyada oo ku xidhan kooban, waxaa jira qeyb ka ah ee jidhadhka samada saddex nooc: dhagax, bir, bir-dhagax.

Farqiyada u dhexeeya jidhadhka samada

naasohoodu wuxuu ka yimid xagga meteorite ka duwan? Su'aashani waxay muddo dheer ku hadhay wax qarsoon in cirbixiyeyaasha, sababta dhawrid iyo cilmi-baarista.

Meteors ka dib duulaankii ee jawi dhulka ee lumiyaan miisaan. Ka hor inta this sari mass wax samadu kama badna toban garaam. Qiimaha Tani waa si aan qiimo lahayn marka loo eego baaxadda dhulka, ka dayrta ee naasohoodu a cawaaqib ma jiri doono.

Meteorites dhacayay dhulkeenna, haysataa miisaan weyn. Chabrovsk meteorite in dushiisa of February 15, 2013 ku dhacay, sida uu ku qiyaasay khabiir, miisaamay toban metrik.

Dhexroor ee jirka Falag buu ahaa 17 m, xawaare ku dhaafo 18 km / s. Chabrovsk meteorite bilaabay inuu qarxi at height ah oo ku saabsan labaatan kiiloomitir, iyo mudada guud ee horyaalka ma badnayn afartan ilbidhiqsi. awoodda qaraxa ahaa soddon jeer ka badan bamka ee Hiroshima, la sameeyey iyadoo ay sabab u gogo badan iyo burbur in dhulka Chabrovsk ku dhacay. Sidaas ku dooday waxa naasohoodu waa ka meteorite ah, ugu horreeya oo dhan kala duwan, waxaan la soco miisaankooda.

meteorite ugu weyn ahaa shayga la ogaado in horrantii qarnigii labaatanaad ee Namibia. Waxay u miisaamay lixdan tons.

dhibic noqnoqoshada

naasohoodu wuxuu ka yimid xagga meteorite ka duwan? Waxaan sii wadi in ay ka hadlaan faraqa u dhexeeya, kuwaas oo jidhadhka samada. In jawi dhulka waa hal maalin oo kaliya waxaa biligleynaya boqolaal malaayiin meteors. In the case of hawada idiin cadeeyo waxaad ka daawan kartaa ilaa hal saac 5-10 "xiddigaha toogashada" in si dhab ah ay yihiin meteors.

Meteorites sidoo kale waa kuwo inta badan isku arkaan on dhulkeenna, laakiin wax badan oo ku gubi xitaa inta lagu jiro safarka. Waayo, maalin ka mid ah weerarada dusha dhulka ee dhawr boqol oo ah jidhadhka samada oo kale. Sababo la xaqiiqada ah in badan oo iyaga ka soo degay oo lamadegaanka ku yaal, iyo badaha, badaha, iyagu ma ay muujiyaan cilmi. Seynisyahanno ee sannadka waa suurto gal inaad wax ka barato oo kaliya tiro yar oo ka mid ah jidhadhka samada (shan xabbadood). Ka jawaabaya su'aal ku saabsan waxa caadi ah in meteors iyo meteorites, waxaan la soco karo ay ka kooban.

halis ku dhacaan

yaryar uu ka samaysan yahay meteoroid yihiin awood u keeni karo dhibaato culus. Waxay keeni dusha madhay ee pride ah, gab karaa shaqada nidaamyada tamarta.

Way adag tahay in la qiimeeyo khatarta dhabta ah ee ay soo rogeen by meteorites. On dusha sare ka dib dhacdooyinka weli tiro aad u badan "nabaro xagtin leh" iyo "bogsiinta". Haddii sida jidh samadu weyn yahay, ka dibna waxa ay ku dhufatey ee dhidibka Earth mowjadda suurto gal ah in Saameynta xun ee cimilada.

Si aad u soo dhaweyneynaa wada baaxadda dhibaatada, ku siin karaa tusaale ka mid ah meteorite Tunguska ah. Wuxuu galay kaynta ku dhacay, taasoo keenta dhaawac weyn u aagga of dhowr kun oo kiiloomitir oo laba jibbaaran. Haddii meesha la degganaa by aadanuhu, waxay noqon kartaa hadal ah oo ku saabsan musiibada dhabta ah.

Meteor waa arrin fudud in waxaa inta badan lagu arkay samada samada. Tarjumay erayga Giriigga ah oo macneheedu yahay "jannada." Meteorite waa hay'ad adag isagoo asal ahaan meel. In tarjumaadda Ruush ah xilli ciyaareedkan u muuqataa sidii "dhagax samada ka."

cilmi sayniska

Si aad u fahamto waxa ururta, iyo meteorites ka duwan meteors, falanqeeyo natiijooyinka cilmi sayniska. Cirbixiyeyaasha ay awoodaan si aad u ogaato in ka dib markii Meteor dhuftay layers jawiga Earth ee waa Laydh iftiimaya. In habka sari weli smear, oo ka kooban gaaska ionized. Qurub Meteor libdhi at height ah toddobaatan kiiloomitir dusha dhulka ee. dhagax xiddig ayaa ka dhigeysa samada samada "dabada." Its ku salaysan waa xudunta u ah, taas oo ka mid ah ciidda iyo baraf. Waxaa intaa dheer, walxaha soo socda laga heli karaa qayb dhagax xiddig ee: carbon dioxide, ammonia, nijaasta organic. badhidii boodhka, taas oo ka dhigeysa in ay mooshin ka kooban yahay qayb ka gaseous.

Marka dhulka jawi sare, meydadka meel halaagnay jajabkii ama qayb ka boodhka waxaa kululeeya oo khilaaf iyo soo baxaan. The yar oo ka mid ah isla markiiba gubay, wuuna ballaadhan yahay, sii waday in ay ku dhici, ballansan raad iska Ifto Yuuna gaaska ionized. Way bakhtiyeen, oo gaarey meel fog qiyaastii siman u toddobaatan kiiloomitir dusha dhulka.

duration Flash go'aamiyo mass jidhka samadu. In the case of naasohoodu sari badan oo ku raaxaysan kartaa dareenka gubashada dhalaalaya dhowr daqiiqo. habka cirbixiyeyaasha Tani wac roob xiddigtii. In the case of Roob naasohoodu saacad keliya a aad ka arki kartaa qiyaastii boqol meteors gubanaya. Haddii tirada jidhka samadu weyn ee geedi socodka of dhaqaaqin Dhulka cufan ee jawi, waxa aan la wada baabbe'een oo gaaro dusha sare ee caalamka. Ka hor inta Earth gaadho wax ka badan boqolkiiba toban ah oo miisaankiisu asalka ah ee meteorite ah.

Iyadoo qayb ka ah birta meteorites ku jira xaddi weyn oo nickel iyo bir. The saldhig oo dhagax ah oo ka mid ah meydadka oo jannada waa silicates: olivine iyo pyroxene. jirka Iron-dhagax leeyihiin tiro ku dhowaad siman ee silicates iyo bir-nickel.

gunaanad

Dadka mar kasta ee jiritaankeeda, isku dayeen in ay wax ka barato jidhadhka samada. jadwalka Star ayaa go'aamisay xaaladaha cimilada, isku dayaya in la saadaaliyo qaddar la kulmay cabsi samada a samada.

Ka dib markii muuqaalka kore ee noocyada kala duwan ee telescopes, cirbixiyeyaasha ay awoodaan inay daaha ka rogaan qarsoon iyo waxa qarsoon badan oo samada samada. Ayaa ururta, loona darsay, meteors, meteorites, ee kala aasaasiga ah iyo mid ahaanshaha u dhaxeeya, kuwaas oo jidhadhka samada. Tusaale ahaan, meteorite ugu weyn, garaacid on dusha sare ee dhulka, wuxuu ahaa bir ah Goba. saynisyahano Its waxay soo ogaadeen in America ee dhallinyaro ah, miisaankiisuna wuxuu ahaa lixdan tons. Best yaqaan nidaamka qoraxda waxaa loo arkaa Halley ayaa dhagax xiddig. Waxaa ku xiran helitaanka sharciga cuf.
