Ke, ilitye: Antarctica, Mexico ...

Ukuwa Ibhanti Emhlabeni - yintlekele siswele zehlabathi. Loo nto yakhokelela ekubeni utshintsho kwimozulu iplanethi yethu, ngenxa apho wafa inombolo enkulu kweentlobo zezinto eziphilayo. Ngokutsho komnye ye hypothesis othembeke kunabo, ezizezi litye ukuba isiganeko ukuphela Permian-Triassic malunga iminyaka emakhulu mabini anamanci mahlanu yezigidi eyadlulayo. zabadla Permian, nangona oko yaziwa kakuhle kakhulu kuluntu jikelele, waba kakhulu buhlungu ngaphezu idayinaso zabadla odumileyo iminyaka engamashumi asixhenxe yezigidi eyadlulayo. Kwimeko yokuqala wafa ukuya kwi-96% ye-iintlobo eziphilayo zaselwandle (ezifana izityalo kunye nezilwanyana). Kumhlaba lalikhona kakhulu ngcono: ngokubulala asixhenxe ekhulwini ngalinye iintlobo ezinomqolo eziphila asibhozo anesithathu ekhulwini iintlobo zezinambuzane. Le zabadla mass of izinambuzane kwindalo wayengasekho, njengoko ezi arthropods Kulula kakhulu ukuba sifunde indlela bume etshintshayo.

Le ntlekele yesibini yaba ngaphantsi buhlungu kakhulu, kodwa ke, kakhulu, kwakukho indawo ye lisalawula yebhayoloji, nto leyo ukuvela kunye nophuhliso ezincancisayo. inombolo hypothesis omnye - eli litye efanayo. Kwimeko yokuqala, abaphandi alatha umngxuma Wilkes Land e Antarctica, apho, ngokwembono zabo, kwabunjwa kukuwa eli litye, wesibini - on the Chicxulub mngxuma eMexico.

Wilkes Land mngxuma na ububanzi of iikhilomitha ezingamakhulu amahlanu. Ifihlakele ngokupheleleyo ngaphantsi kwe ice iqokobhe Antarctica, ngoko ukufunda alikafiki kunokwenzeka. Kodwa ngo-2009 kwaye lwenziwa izifundo radar, bafumana ukuba unalo luphawu ukuma yimingxuma nefuthe kwakheka kwi ndawo eli litye okanye zimpahla enkulu. Crater Chiksulub ezincinane kakhulu kwaye ububanzi of ikhulu elinamanci asibhozo km. Oko kukuthi ubungakanani litye bawile kuxhomekeke isikali kukutshabalala eziphila.

Izazi akukho ukuvumelana malunga uhlobo isiganeko nefuthe - ukuwa eli litye, yaye ezinye - kukuwa zimpahla, enomsila okanye enye into. Abaphandi isibhakabhaka akakwazi ukugweba ukuba imizimba yasezulwini kufuneka zihlelwe izijikelezi-langa ezincinane, yaye yintoni - to awe kunye iiplanethi. Kwiminyaka esixhenxe eyadlulayo, le pundits baye bagqiba ekubeni anikezele iklasi entsha imizimba yasezulwini. It bhalisa izijikelezi eziliqela ezinkulu demoted isikhundla kule planethi iPluto. Iklasi yagqiba ukuba kuthiwe "kwiiplanethi ezincinanana." Innovation ayenziwanga jikelele yamkelwe, njengoko izazi abaninzi bakhuphisana ngokufaneleka yokuhlela entsha.

Kwenzeka ntoni phakathi ku-Februwari isiganeko Lahexa eRashiya, ingakumbi - phambene. Le eziwa, owawa kufuphi saseChelyabinsk, iingcali ukusuka NASA ingqalelo ukuba likhulu uluntu waphawula emva Tunguska. Kwimemori yabantu yokuba zimpahla leyo eyabangela umonakalo ezininzi nokwenzakala. Nangona iyangena phambi kokuba afike emhlabeni, wakwazi ukuba ukwenza ezininzi iingxaki, onakalise ivenkile omnye esityalo eChelyabinsk. Lo matshini ingxelo ukuba zimpahla - sisandulela eli litye uya kudlula kufutshane Earth, kwaye kukholeleka ukuba uya kuwela entsimini umtsalane iplanethi yethu.

Okubangel 'umdla kukuba, loo awe kwi Urals yinto phantse eziqhelekileyo, eyakhe, lweenkobe. A encinci kwingingqi eChelyabinsk (ngaphantsi kweentsuku ezingamashumi alithoba amawaka ezikwere zeekhilomitha) kule minyaka yokugqibela asixhenxe anesihlanu okwesihlandlo sesithathu uba iziko yomtsalane ukuba iindwendwe ezivela ngaphandle. Ngowe-1941-m kunye-m 1949 ibekwe kwindawo ebingasentla komzi ka Katav-Ivanovsk kwilali Kunashak bawe awe esibhakabhakeni, nangona incinane kakhulu ngobukhulu. Zonke ezintathu sidityaniswe kwi crash ye ubude line phantse tye akukho kweekhilomitha ngaphezulu amabini anamashumi mahlanu. Ezo ayevela yoxinaniso kwi indawo elinganiselwe kwixesha elingephi wexesha akafumaneki naphi na ehlabathini. Kaloku, nje eyimfihlakalo ezinye!

Le ngozi kwi Urals lubonise ukuba ungakhuseleki bombardment evela emajukujukwini na. ERashiya, waqalisa uphuhliso lwenkqubo iminyaka elishumi yokukhuselwa ukusuka izisongelo yesiqalo.
