Pfungwa, mabhaisikopo, mapoka evanhu kunyangwe mamwe manyuko enhau. Izvo zvakambotaurwa kare nezvekuti meteorite yaizokanganisa nyika yedu. Nekudaro, sezvazviri chokwadi kuti hatina kumborarama seshiri uye hatina kukwanisa kunyora, zvakawanda zvakafungidzirwa uye kufungidzirwa nezvazvo. Asi… ndeipi mhedzisiro inogona kunge iri?
Gore rino, mamwe ari pedyo-Earth asteroid apfuura. Mazuva mashoma apfuura, iyo asteroid Florence, ine saizi ye4,4 km, yakapfuura padyo nepasi redu chinhambwe chemamirioni manomwe km. Kunyangwe yaive isiri nengozi, sezvo yaive pachinhambwe chingangoita gumi nesere icho chinotiparadzanisa neMwedzi, zvinokwanisika kuti vazhinji venyu makashamisika kuti chii chingaitika kana chaive nemhedzisiro inouraya. Kune zvimwe inri, uno unouya Gumiguru, asteroid 2012 TC4 pakati pemamita gumi nemashanu nemakumi matatu pakudarika, ichapfuura makiromita 15 chete kure
Kukuvadza kwakasimba maererano nehukuru
Pakutanga, zvinofanirwa kucherechedzwa kuti kukanganisa kubva kune mudiki meteorite hakuna kufanana nekukanganisa kubva kune hombe. Uri wega mumakore ekupedzisira makumi maviri, zvinofungidzirwa kuti vakanganisa vangangoita mazana mashanu. Kuve mudiki, zvinokwanisika kuti vazhinji vanofuratira idzi data nekuti havana kuisa njodzi. Saka nematanho ayo, tinogona kutanga kutaura, mhando yecrater yavaizosiya uye kukuvara kwavangakonzeresa pairi. Mukana iwo aive akakura meteorite, yakaipa kukuvara.
Meteor diki, 100 metres kureba, ingakonzeresa crater 3km dhayamita uye kukanganisa 60km radius.
Kana iyo meteorite yaive 1km dhayamita, apa taitowana makiromita makumi maviri nemashanu nekuparadzwa zvachose kwezvose zvaive munzira ye25km.
With the meteorite hombeSezvo kutanga kwe10km, isu taitova nematambudziko akakomba. Kukanganisa kwayo kwaizokonzeresa crater ye200km ine zvachose kuparadza zvese 3000km kure.
Migumisiro yemamiriro ekunze yaizoitika pasi pano
Kupinda muchadenga cheimwe yemitumbi mikuru pane anopfuura zviuru zana zvemamiriyoni / h kunokonzeresa, kubva pakutanga, kukanganisa kwewairesi neterevhizheni. Pavaipinda, ivo vaitevera dutu rine simba rine mhepo mumatunhu ese ari pedyo. Zvichienderana nezvatakataura, saizi yayaive nayo. Kamwe payakarova, chero yaive nzvimbo yacho, kudengenyeka kwenyika kwakateedzana. Kunyangwe munzvimbo dzavakange vasina kumbovapo. Zvino, ichibva pano, inogona kuwira munzvimbo dzine kutenderera kwepasi kuri nyore uye ivo vanogona kunyange kumutsa kuputika kwemakomo anoputika zvinoenderana nekwawakawira.
Mushure mekukanganisa kwemeteorite, gore hombe gobvu raigona kuzadza pasi kana kuzadza nyika. Shawa remararawo, raizokandwa pakutanga. Gore hombe irori raizodzivirira Zuva kuti risaonekwa kwemwedzi. Icho kutonhora kwaizove kwakatarwa pama thermometer uye muchimiro chechando. Zvishoma nezvishoma, zvirimwa zvakawanda zvaizofa. Nzvimbo dzakanyanya kubatwa neizvi dzinogona kukonzera kufa kwemhuka dzinotyisa. Kufa kwavo kwaizoperekedza mhuka dzinodyawo dzichinyangarika.
Mhedzisiro chaiyo yemeteor ichirova Pasi
Kutenda paleontology uye paleoclimatologists, mukana weimwe yezviitiko ichi kuitika zvakare wakadzidzwa. Kubva pane zvakawanikwa, takaona kuti kukanganisa kwe 1km-saizi meteorites inoitika yega yega mamirioni emakores. Kune vakwegura, avo ve 10km, mukana unodzikira kusvika pa1 mamirioni mazana matatu nemakumi matatu emakore. Neraki, icho chinhu chinotisvitsa kure kwazvo. Tinogona kuwana pano chimwe chezvikonzero uye dzidziso dzaizotsanangura chikonzero chekutsakatika kwemadinosaurs.
Sezvo isu tisingakwanise kutonga zvachose kuti chiitiko chakadai chinogona kuitika rimwe zuva, NASA yakatotora danho panyaya iyi. Ivo vanotova nezvinoedzwa vakamirira kutsausa meteorite ayo rimwe zuva angaunza njodzi chaiyo kwatiri.
Ndinovimba zvese izvi dzidziso yakachena, uye kuti hatimbofaniri kuona mhedzisiro yakaipa yedombo hombe kurwisa nyika.
Zvinoenderana nezviporofita zvaNostradamus mune ramangwana asteroid inonzi an10 1999 icharova Mediterranean.
