Kutheni Dinosaurs: ukuthelekelela nezesayensi

Dinosaurs asingabo elishumi yokuqala yokuba umbandela ingqalelo abantu abaqhelekileyo nje kuphela, kodwa izazi. Bazama ukuba bafunde ngezi zidalwa angaqondakali yonke into ukususela njani emhlabeni lo hlobo ophela ukuba kutheni iidayinaso saphela. isihloko yokugqibela Nangona ochaphazelekayo izazinzulu ezininzi abaphuhlisa nyaka ngamnye ngakumbi yaye iinguqulelo ezininzi ezintsha.

Dinosaurs saphela ukusuka ngokuhlasela komhlaba

Hayi, ita kungafuni ayehlasela yabasemzini. Kulo mzekelo, esona sizathu siphambili ekutshabalaleni elipheleleyo iidayinaso ibonisa umsebenzi ngayo imizimba yasezulwini. Kukholelwa ukuba iidayinaso wafa ngenxa yenye yezona zinto zilandelayo: kukuwa ke, ilitye elikhulu, umphezulu ezininzi "bombardment" izijikelezi bomhlaba, yokungqubana umhlaba kunye enomsila kunye nokuphuculwa radiation ngenxa dubulo supernova okanye ezinye izinto zohlobo olufanayo.

izifundo zokwakheka komhlaba ngokuphindaphindiweyo yaqinisekisa yokuba phezu komhlaba iye phantsi ngokuphindaphindiweyo ukuba kuwa izijikelezi ezahlukenenyo. Xa ukubeka phambili uguqulelo malunga kutheni iidayinaso saphela, amalungu e-worldwork theory of "bombardment zigwencela" abonisa umhla uqikelelo yokufana sokuwa kwabo kunye zabadla ngobuninzi dinosaur. Kubalulekile ukuqaphela ukuba le mbono, oosonzululwazi ngokuyinxenye kuphela baxhasiwe: zesayensi bathi kwakwanele edinokratnogo ukuwa, izifundo ucaphula Crater Chicxulub kunye izibalo ngeenkwenkwezi zehlabathi zingagilani kunye nezinye imizimba yasezulwini. Zizinto komhlaba eziphikisayo kunye paleontologists, ekhala ukuba iinguqu ezinkulu kulo izilwanyana ngaphantsi komhlaba nga kwenzeka kuphela nje ngenxa yokuncipha ngokuphindaphindiweyo. Yiba ukuba njengoko ukuze; kulo mzekelo akunamsebenzi kuzo iidayinaso ukusuka edinokratnogo ezininzi okanye asteroid. Eyona nto ibalulekileyo kukuba ngenxa yale uninzi lweentlobo zitshatyalalisiwe ukuba phantse edinomomentno.

Beka phambili ngendlela eyahlukileyo kwabo njengoko oyena nobangela iingongoma ukufa ukunyuka kwamazinga kwemitha. Esi siganeko, izazinzulu, kukhokelele kwinto yokuba Umhlaba waqalisa ukufumana kwelanga ngaphantsi ngenxa iinkqubo ngokwasemzimbeni yemichiza ezenzeka ojikeleze umhlaba. Ngenxa yoko, kwakukho kobubi ngokubanzi ukuba ifuthe elibi kwiintlobo zinegazi elibandayo. Ngaphezu koko, isixa-radiation ukuba liye langena nge kweemaleko esesibhakabhakeni, naye waba nefuthe elibi iinkqubo zebhayoloji yokuzala, batsho phantse ku nothi.

Thaca le ngcamango kutheni iidayinaso saphela, ukuba, ngokungathi kunjalo, ezinomsebenzi-macala. Njengoko umthetho, yonke hypothesis eyakhelwe pundits "komhlaba" abo abameli kwenye yezi nkalo zophando. Ukuba oku alisayi kuwathathela ngqalelo ezinye izinto ngokupheleleyo ngakumbi kukuxelela kwezinto eziphilayo.

version eziphilayo

Ukuba bajike baye thixweni iinzululwazi, kuyenzeka ukuba amsunduze enye inombolo beengcamango malunga nokuba kutheni iidayinaso saphela ukusuka. Eyokuqala kwezi thiyori utshintsho ehlabathini woMhlaba. Kuye kuthathelwa ingqalelo inani lemiba, oko kukuthi, intshukumo amacwecwe, ukutshintsha inqanaba ulwandle kwehlisa, njengoko njengesiphumo ezimbini zokuqala - uyaxhuma kwamaqondo obushushu kunye notshintsho kulwakhiwo enezityalo kunye nomoya.

Inguqulelo yesibini kutheni iidayinaso saphela, oko notshintsho izilwanyana wonke umhlaba, ngokusekelwe intshukumo ye ziitectonic plates. Ngenxa yoko, amarhamncwa bakwazi ngempumelelo ngakumbi kutshabalalisa iidayinaso abaselula kunye amaqanda, yaye ngaloo ndlela nokulawula indlela yokuzala ezi zilwanyana kwicala yokunciphisa.

Zizo ezi ngcamango eziziintloko azame ukucacisa ukuba kutheni iidayinaso saphela. Njengoko ubona, ngamnye kubo uxhomekeke kuyo nayiphi na into enye, yaye intsalela ngqalelo yesibini. Yiyo loo nto kubalulekile ukuba ukudibanisa iinxalenye yeengcinga zingqinwa bubungqina myalezo, kwaye zisekelwe phezu umboniso omnye.
