Roob Meteor - demisaan ololaysa Samooyinka

Meteor roobka, ka durdur dab samada ka - mid ka mid ah ifafaale ugu quruxda badan, jaceyl iyo dahsoon, ina siiyey in ay dabiicadda ka weyn. Secrets of yar jidhadhka samada, la joogto Garaaci weerarka our "kubada buluug" imprinted on bogagga taariikhda dhulka, iyo derdertay in khuraafaadka aadanaha iyo halyeeyadoodii hore. Laakiin roob naasohoodu waqtiyo xanbaarsan yahay khatar weyn caalamka, taas oo aan la socday oo kaliya iyada oo loo marayo meteorites dayrta, waxay keeni burburinta Joogaba, apocalyptiga. Su'aasha ma aha in mar kale dhici doona, iyo goorta ay dhacayso aafadaas noocan oo kale ah. Iyo in tartanka aadanaha ayaa diyaar u ah in ay la tacaalaan cawaaqibka ay musiibo?

Su'aalahani waxay si fiican u jawaabi kartaa wargeeyayaasha caalamka - meteorites. Waxay yihiin nooca "code of badbaadada" for tartanka aadanaha. roob Meteor, oo ka kooban walxo gudbaya ma aha oo kaliya nidaamka qoraxda, laakiin sidoo kale kumanaan iyo malaayiin sano oo iftiin ah oo meel, waxay keentaa in Earth macluumaad qiimo badan oo ku saabsan Caalamka kale, hodmin dunida ka mid ah sayniska aqoon cusub qiimo. Baadhitaanka ayaa ka mid ah "hadiyado Caalamka" inoo siin karaa inaannu wax fikrad ah in ay waxyaalaha qarsoon oo badan oo caalamka iyo meel ee dhulkeenna ku sugan. Dadka weli u decrypt meel fariinta.

Earth, sida meerayaasha kale, oo ay taariikhda oo dhan, si nidaamsan u sakhiray in ay "Qaraxii" oo alaab ah meel yar. Inta badan, oo ay size waa mid aad u yar, oo inta badan oo ka mid ah "wargeeyayaal samada", taas oo ka dhigi ilaa roob Meteor, ma gaari dusha caalamka ayaa, ee cufan gubanaya layers of jawiga. Taas oo saamaynta waxa loogu yeero "xiddigaha toogashada."

Laakiin taariikhda evolutionary Dhulka iyo ogaa saamaynta aad la taaban karo. Meteorites inta badan baa dhici lahaa cawaaqib xun. On jirka ah ee caalamka waxaa ku jira wax badan oo ka mid ah "boogta Star" - bohol weyn sameeyay oo sabab u ah shilalka runtan. Marka xataa meteorite degaanka ee casriga dhexe ee Mexico dhicid beddeli taariikhda dhulka, oo burburiyey dinosaurs (iyo wejiga dhulkeenna iyo cimilada bedelay). Haddii aan musiibo this epochal, dadka on Earth marnaba muuqan kari lahaa. Heysatay waqtiga xamaarato Rafaa waxaa si fudud looma ogola in la horumariyo noocyada aadka u abaabulan kale nolosha.

Shan iyo lixdan milyan oo sano ka hor Earth ahaa mid aad u kala duwan. Markaasaa waxaa u ahaa ka diirran yahay sida ay hadda tahay. Dinosaurs ahaayeen foomka ugu sarraysa ee horumar innoo oo mar tegey hore ee wareega taariikhda dhulka ee, iyada kursiga ku leh Dadka iyo nuujiya. meteorite hal A, kuwaas oo noo yimid ka bixiyo mugdiga ah ee bannaan, weligiis koorsada taariikhda Earth beddelay.

suunka asteriyoodh The, oo ku dhashay laba boqol oo milyan oo sano ka hor dhacdada Epoch-samaynta this, wuxuu ahaa ku dhashay ee shayga, taas oo door muhiim ah nolosha dhulkeenna. Balaayiin jajabkii dhagax weyn u dhaqaaqo iyada oo fiidkii meel hal jiho, sida baabuurta jidka. All - marka laga reebo mid ka mid ah dhagax weyn, ordaya Dabcan dadab gebi ahaanba ka duwan. Waxa ay aheyd mid ah size cajiib ah oo ah safarkii siddeed iyo toban kiiloomitir u ballaaran, si lama filaan ah hor istaagay waddada. Taas oo kaliya u dhaqaaqay this "trailer" at heerka of 38 kun. Km / h. Sidaas darteed of isku dhaceen asteriyoodh kale, labadan shay bakhtiistay galay a million oo gogo '. Laakiin mid jab, taas oo ahayd in ka badan toban kiiloomitir dhexroor, ayaa aayahooda gaar ah ...

Waxa uu dhawaan ahaa in uu la kulmo saddexaad, meeraha keliya ee deggan ee Nidaamka Solar, weligiis beddelo taariikhda iyo mabaadiida horumar. Tani "gantaal meel" ma ahaa si shisheeye dunida sida laga yaabaa in ay u muuqato. Sida dhulkeenna laftiisa, waxaa ka koobnayd inta dhagaxa iyo biyaha. More hufan, jirkiisa, kaasoo noqda nolosha-siinta dareeraha this in vacuum dibadda ah.

Laakiin meteorite gudaha bubbled is biirsaday kiimikada ee hydrogen, carbon iyo oxygen - qaybaha ugu muhiimsan ee nolosha. Like wax, sida muuqata, iyo mar aasaaska nolosha saaray dhulkeenna, taas oo ah taajka wakhtigaas ahaayeen dinosaurs ah. Sida aad u Dhawaanina Dhulka, cuf caalamka ee ilaa qarxay this 'dilaaga ka meel dibadda ah "in heerka of 80 Km kun. / H. masiibo waxa uu ahaa lama huraan, gaar ahaan siiyey mass ee meteorite ah, si deg deg ah ku yaacaya kulan la dusha sare ee dhulka. Sida la og yahay, wakhtiyada mass xawaaraha uyeelaysaan kuwo ciidanka.

Marka meteorite a galay jawiga, khilaaf u beddelaa gilay bartamaha, hareereysan plume plasma ah. Under saameynta ay heerkulka oo aad u sarreeya tan iyo bilowgii ay u kala soocaan u tiro aadka u badan ee burburka la shubay. Afar daqiiqo waxaa isagii ka qaaday in ay ka gudbaan Atlantic ah oo soo dhaadhac madaxooda iyagoo leh, mana dinosaurs jaahiliinta on. Sayidka, sida uu sayniska casriga ah, waxa ay ahayd roobka naasohoodu ugu ba'naa oo beddelaya nolosha ee taariikhda dhulka ee.
