Le Meteor yahlukile evela zimpahla? Inkcazelo, imizekelo eziwa kunye namatye awe esibhakabhakeni

Thetha ngento eyahlukileyo ukusuka zimpahla Meteor ukwazi imfihlelo nezinto ezahlukileyo nesibhakabhaka esimnyama. Stars Abantu bathembela yiminqweno yabo nesizixabisayo, kodwa siya kugxininisa kwezinye imizimba yasezulwini.

iimpawu Meteor

Igama elithi "Meteor" linxulunyaniswa ngezenzeko ezenzeka kwi-atmosfere, apho ngeqondo ebalulekileyo ehlaselayo namaqumrhu angaphandle. Amasuntswana mancinane kangangokuba intshabalalo ekhawulezileyo kwenzeka phantsi amanyathelo kunobunye.

Musa ukuya eziwa kumphezulu? Inkcazelo ezi imizimba yasezulwini, esiphakanyiswa izazi, ayiphelelanga ebonisa wachuba iindawo ezimfutshane amnandi ukukhanya nesibhakabhaka esimnyama. Iinzululwazi zizibiza ngokuba "iinkwenkwezi ukudubula."

Iimpawu wazo

Le eziwa le kumabhodlo meteoroid efikelela phezu komhlaba wethu. Kuxhomekeka ekwakhiweni, kukho iCandelo imizimba yasezulwini ngokwendidi ezintathu: ilitye, intsimbi, intsimbi-ilitye.

Umahluko phakathi imizimba yasezulwini

Le Meteor yahlukile evela zimpahla? Lo mbuzo uye ibisoloko ingaziwa ukuba izazi, isizathu lokuqaphela kunye nophando.

Emkhathini emva ayehlasela ojikeleze umhlaba ukunciphisa umzimba wabo. Ngaphambi ukutshiswa mass into yasezulwini ayidluli grams ezilishumi. Eli xabiso babambanayo mncinci kakhulu xa kuthelekiswa kubungakanani boMhlaba, ukususela kukuwa Meteor akukho iziphumo ziya kubakho.

Ayevela uyakuwa kwiplanethi yethu, ube nelitye ebalulekileyo. EChelyabinsk eziwa elehla phezu kaFebruwari 15, 2013, njengoko uqikelelo abaziingcali, ubunzima malunga ezilishumi neetoni.

Sangqa sezijikelezi 17 m, i uqina ligqithe 18 km / s. EChelyabinsk eziwa waqala umlilo nomphakamo kweekhilomitha malunga mabini, kwaye ixesha lilonke moya zange ngaphezulu kwimizuzwana engamashumi amane. amandla dubulo amaxesha amathathu ngaphezu kuqhuma Hiroshima, kwasekwa ngenxa lamaqhosha ezininzi kunye amaqhekeza wawa emhlabeni eChelyabinsk. Ngoko babebanga ukuba yintoni Meteor eyahlukileyo ukusuka esibhakabhakeni, kuqala kwiinto zonke, siphawula ubunzima lwabo.

Le eziwa elikhulu injongosenzi ibonakele kule nkulungwane yamashumi amabini okuqala Namibia. Kweekhilogram ezili zaba ngamashumi omathandathu.

frequency drop

Le Meteor yahlukile evela zimpahla? Siyaqhubeka ukuthetha ngomahluko phakathi kwezi imizimba yasezulwini. Xa umoya ehlabathini imini enye kuphela apho avela amakhulu ezigidi eziwa. Kwimeko lwemozulu ecacileyo Nani linganisani malunga nelixa 5-10 "ziinkwenkwezi ezibinzayo" ukuba eneneni onyamalala.

Ayevela nazo kaninzi ukufumana ngokwabo kwiplanethi yethu, kodwa uninzi lwabo aqhumisele nkqu ngexesha hambo. Ngokuba imini elibethayo kumphezulu womhlaba ezilikhulu embalwa imizimba yasezulwini ezinjalo. Ngenxa yokuba uninzi lwabo ziwela entlango, iilwandle, iilwandle, abayi ukubonisa abaphandi. Izazinzulu yonyaka kunokwenzeka ukufunda kuphela inani elincinane kwezi imizimba yasezulwini (iziqwenga ezintlanu). Ukuphendula umbuzo malunga koko eziqhelekileyo eziwa kunye namatye awe esibhakabhakeni, sinako qaphela ukwakhiwa kwawo.

ingozi ukuwa

ngamasuntswana amancinci ezakha meteoroid bayakwazi ebangela umonakalo omkhulu. Bona kukhokelela kumphezulu eligugileyo ye kwisiphekepheke, Uyakwazi ukukhubaza umsebenzi lwezixokelelwano zabo zamandla.

Kunzima ukuba ukuvavanya ingozi ebangelwa awe esibhakabhakeni. Phezu emva izehlo uhlala isixa esikhulu 'loloyiko "yaye" baphiliswe ". Ukuba ibhunga yasezulwini enjalo elikhulu, ngoko hits esqwini Umhlaba lisisiqalo kunokwenzeka ukuba nefuthe elibi kwimozulu.

Ukuze ukuqonda ngokupheleleyo ubukhulu bale ngxaki, uyakwazi ukunika umzekelo Tunguska zimpahla. Watsho wawa ehlathini, ebangela umonakalo omkhulu kummandla amawaka aliqela ezikwere zeekhilomitha. Ukuba indawo kuhlale abantu, kungaba intetho malunga intlekele yokwenene.

Meteor i isenzeko ukukhanya sivame kwi nesibhakabhaka esimnyama. Liguqulwe lithatyathwa kwigama lesiGrike elithetha "wasezulwini." Eziwa umzimba okuqinileyo ukuba imvelaphi isithuba. Xa inguqulelo Russian kweli xesha kuvakala ngathi 'ilitye esibhakabhakeni. "

uphando lwezenzululwazi

Ukuze siqonde oko enomsila kunye namatye awe esibhakabhakeni zahluka eziwa, ukuhlalutya iziphumo zophando lwezenzululwazi. Ngeenkwenkwezi bakwazi ukufumana ukuba emva kokuba Meteor betha ungqameko koMhlaba kukuba ezidanyazayo zabo. Kwinkqubo yokutsha kuhlala smear, eliquka igesi insimbi. amasuntswana Meteor luphele nomphakamo kweekhilomitha asixhenxe ukusuka kumphezulu womhlaba. Le enomsila ushiya nesibhakabhaka esimnyama "Yibambe ngomsila." Isisekelo sayo undoqo, equka uthuli kunye ngumkhenkce. Ngaphezu koko, ezi izinto zilandelayo kungenziwa akhiwe kule nonomgca: carbon dioxide, ammonia, ezingcolisa organic. Uthuli nomsila wayo, leyo isishiya siyahamba wayo amasuntswana sukube.

Ngenye emoyeni ejikeleze umhlaba, izidumbu isithuba batshatyalaliswa iziqwenga okanye amasuntswana uthuli ukuba elibaselwe ngumoji zochuku qwele. Zincinane kubo ngoko nangoko utshiswe, yaye elikhulu, baqhubeka kuwa, ugcine umzila ezikhanyayo yerhasi insimbi. Bona licinywe, zifikelela umgama malunga ulingana km asixhenxe ukusuka phezu komhlaba.

Flash Ubude emiselwe ubunzima umzimba yasezulwini. Kwimeko Meteor yokutsha enkulu kunandipha ukukhanya okukhulu imizuzu embalwa. Le nkqubo izazi kubiza imvula inkwenkwezi. Kwimeko ishawa Meteor kwiyure enye ungabona malunga nekhulu eziwa avuthayo. Ukuba ubungakanani umzimba yasezulwini ezinkudlwana inkqubo ihamba emkhathini Umhlaba ashinyeneyo kaThixo, ukuba lingapheli yaye ifikelela kumphezulu womhlaba. Ngaphambi Earth ifikelela akukho ekhulwini ngaphezu ezilishumi ubunzima wokuqala zimpahla.

Njengenxalenye intsimbi awe iqulathe isixa esikhulu nickel kunye nesinyithi. Isiseko welitye zamaqumrhu basezulwini silicates: olivine kunye pyroxene. umzimba Iron-ilitye kufuneka inani phantse ngokulinganayo silicates nentsimbi-nickel.

isiphelo

Abantu ngawo onke amaxesha bobukho bayo, wazama ukufunda imizimba yasezulwini. nekhalenda Star babezimisele iimeko zemozulu, ukuzama ukuqikelela isiphelo zafumana yokoyika a nesibhakabhaka esimnyama.

Emva kokuba ukuvela kweentlobo ezahlukeneyo ngeeteleskopu, izazi nako ukusombulula intsinda-badala iimfihlelo ezininzi neemfihlelo nesibhakabhaka esimnyama. Ziye ezinomsila ngokubanzi ngaye, eziwa, awe, kokuhle ezingundoqo ezifana phakathi kwezi imizimba yasezulwini. Umzekelo, emkhathini inkulu, bendibetha phezu kobuso bomhlaba, yaba intsimbi Goba. izazinzulu ayo baye bafumanisa kwi Eselula eMelika, ubunzima baso malunga neetoni mathandathu. owaziwa kakhulu kwinkqubo elanga uthathwa comet Halley kaThixo. Elidityaniswe kunye kokufunyanwa umthetho womxhuzulane.
