Ukuwa Ibhanti Emhlabeni ngo-2017

Asteroids, nto leyo kwixesha elizayo kunokuba ngakumbi Umhlaba kumgama million 7.5 khilomitha, iyaqwalaselwa zingabangela ingozi Earth. iplanethi yethu iye nakanye senze ngala maqurhu yesiqalo. Namhlanje siye sithethe malunga njengokuntlithwa uyingozi Emhlabeni kwaye kukho ikamva kwangoku, amathuba ziintlekele? Kwaye ukuba siqale yesalathisi encinane nembali.

Yintoni Ibhanti?

Ibhanti (ukusuka yesiGrike. "Star-like", "inkwenkwezi") ukwabizwa ngokuba umhlaba encinane. It is a umzimba yasezulwini km ezinkulu kuno-30. Abanye babo baye Hewana zabo. A lot of izijikelezi uhamba wezijikelezi-langa. kwiminyaka million 3.5 eyadlulayo, uMhlaba Iwile inani enkulu izijikelezi ezakhokelela utshintsho zehlabathi.

Khondo of asteroid yamandulo

Ngentwasahlobo yowama-2016 e-Australia, zokuma baye bafumana izinto ezidibene eli litye, netoti emalunga 30-40 km. Oko kukuthi ubungakanani ngayo ifaniswe satellite encinane. Ukuwa unobangela inyikima-11, itsunami kunye zibhuqiwe ngokubanzi. Mhlawumbi omnye izijikelezi-langa ezincinane, nto leyo ekhokelele kuwa emhlabeni wabumba kuphela nasekuthwaseni ebomini, kodwa bakha ukwahluka ongqonge umhlaba onokuphila.

Kukwakho uluvo lokuba zanyamalala obufihlakeleyo iidayinaso kungenxa kukuwa ilitye elikhulu eMhlabeni. Nangona oku nje enye iinguqulelo ezininzi ...

Yinto fun! An impembelelo wamandulo mngxuma Chicxulub kwasekwa ngenxa yentlanganiso zimpahla. Ubunzulu Its kanye ode waya kufikelela km 20. Ukuwa emkhathini yabangela tsunami, kunye nokutshintsha kwemozulu, ngathi ubusika zenyukliya. Ukongezelela, kwiminyaka ukuya ku-16 on Earth unokuwela ku-26 degrees lobushushu.

eChelyabinsk eziwa

Ukuwa Ibhanti eMisaveni ngoFebruwari 2013 wayengomnye mlonyeni iziganeko kungekuphela eRashiya kodwa ehlabathini lonke. Lo ke, ilitye, ogama ubunzima wafikelela iitoni ezili-16, ngokomkhethe utshiswe emoyeni, kodwa inxalenye yawo omncinane wawa kufuphi saseChelyabinsk, ngethamsanqa, eziphaphazelayo phezu kwayo.

Ngaloo nyaka, waya phezu kwesi sixeko phambene, leyo wakhonza njengesiseko igama layo. Umzimba ngokwawo kakhulu luqhelekile yayiquka chondrites, kodwa itsale ixesha umdla kunye nendawo elishweni lakhe. Akukho nasinye izijikelezi afwile Earth musa kwabanga umonakalo, ekubeni angawi kufutshane kwidolophana enabantu abaninzi. ubunzima esibhakabhakeni yaba etoni 6. Oluwe edikeni Chebarkul zimpahla wamphatha yeni iifestile kwisakhiwo 7000. Abantu 112 baye esibhedlele kunye ukutsha, abantu abambalwa abaninzi babhenela koogqirha uncedo. Xa zizonke, lo okubulala itshayelwe 6,5 amawaka square metres.

Umonakalo omkhulu odalwe Ibhanti, bekuya kuba phi ebaluleke ngakumbi ukuba izulu litye yeyela emanzini kunye nomhlaba. Ngethamsanqa, eli litye phezu komhlaba akuthethi etshintsha abe intlekele ngomlinganiselo omkhulu.

I eyingozi ngakumbi kukuwa ekuneni kwemvula enkulu kwi Umhlaba?

Ngokutsho izibalo izazinzulu, ukuwa Ibhanti Emhlabeni unako ukubangela umonakalo omkhulu xa malunga 1 km emzimbeni ubukhulu iza kuwa phezu komhlaba komhlaba. Ubukhulu becala kwakhiwa ifanele sangqa nama-15 km, oko kuya kubangela uthuli ukungena emoyeni. Kwaye oku, nto, nto leyo ekhokelela kwimililo ezinkulu-scale. Uthuli, afudunyezwe lilanga, ukunciphisa izinga ozone ekukhawuleziseni indlela kwemichiza kwi stratosphere, ukunciphisa ubungakanani imitha yelanga efikelela kumphezulu-langa.

Ngoko ke, ifuthe eli litye Emhlabeni kuyingozi kakhulu. lobushushu Global Earth lihla kwi-8 ⁰ C, ebangela ice yobudala. Kodwa ukuze kungakhokelela ekutshabalaleni uluntu, eli litye kufuneka izihlandlo ezili-10 ngaphezulu.

ingozi giant

Kutshanje, izazinzulu ziye zafumanisa ukuba uluhlu nobungozi ukuba iplanethi yethu ukuba ziquka centaurs - ilitye omkhulu ububanzi of km-50 ukuya 100. Intsimi omxhuzulane ezinye iiplanethi qho kwiminyaka million 40-100 abaphose kwicala Umhlaba wethu. Inani labo liye landa kakhulu ngoku. Mhlawumbi xa litye omkhulu eMisaveni kwixa elizayo, oosonzululwazi rhoqo kubalwa, nangona ekubaleni nesikhokelo kukuwa centaur - nzima kakhulu umsebenzi.

Ukongeza, uluhlu nobungozi Emhlabeni ziquka:

• kuqhuma supervulkanicheskoe;
• bhe jikelele;
• Ibhanti (0.00013 kwi%);
• yimfazwe yenyukliya;
• intlekele yendalo.

Ingaba eli litye uya kuwela Earth ngo-Oktobha 2017?

Eyona enkulu, nto leyo echaphazelekayo ngoku oososayensi - kukho ingozi eli litye, ubukhulu apho amaxesha 2 ngaphezulu kwe eChelyabinsk zimpahla. Kukho amathuba ukuba isiganeko siza kwenzeka ngo-Oktobha 2017, nto leyo eza kuxhokonxa kukho iintlekele makhulu kakhulu kunokuba hit ngo-2013. Isazi ngeenkwenkwezi uJudith nerayi- uthi ubukhulu eli litye afikelela km 40. into lakhe elibizwa WF9.

umzimba Eyingozi wasezulwini kwafunyaniswa zizazinzulu e Hawaii umva ngo-2012. Ngaloo nyaka waba kude kufutshane kakhulu ukusuka uMhlaba, kunye Oktobha 12, 2017 kuya kufika sisondela kakhulu yingozi umgama iplanethi yethu. Izazinzulu zikholelwa ukuba ukuba eli litye Emhlabeni kuthatha ngokwenene ndawo, oko kuya kubonakala kuqala yi-British.

Okwangoku, oosonzululwazi ngenkuthalo ukufunda ithuba ukungquzulana. Noko ke, amathuba eli litye Emhlabeni lincinane kakhulu yaye, ngokutsho kwabaphengululi, 1 yesigidi. Noko ke, kusekho apho.

sisengozini

Kufuneka kuqatshelwe ukuba rhoqo ukubhabha izijikelezi ezithile ezinobukhulu obahlukileyo yi-Earth. Ba yingozi, kodwa kunqabile ngenene liwele Earth. Ngoko ke, ekupheleni kuka-2016 iye yabhabha ezidlulileyo Umhlaba kumgama umzimba 2/3 umgama ukuya enyangeni, ubukhulu kwilori encinane.

Kwaye ngoJanuwari 2017 yabalasela ukubhabha umzimba wasezulwini, ukufikelela ubungakanani yesakhiwo esinemigangatho-10. Indiza ngaphakathi 180.000 km ukusuka kuthi.
