Ndechekare zvakadini Earth?

Pfungwa masayendisiti akawanda uye vanhuwo zvavo kare akamutsa mubvunzo: "Chii nemakore Pasi"? Pari kupfuura nzira yakakurumbira yokuziva makore zvisaririra ndiyo radiocarbon kudanana. Asi kunyange akasimba nzira ine zvinokosha zvikanganiso. Munguva ichangopfuura, masayendisiti akaona kuti mwero kuora radioactive zvinokonzerwa zvinhu zvakawanda, saka tora rive dzose hazvibviri. Uyewo, pane dzimwe pfungwa dzakawanda kuti vanobvumirwa, asi iwe unofanira kuongorora navo chete pachiimbwa dzimwe zvine chokuita dzidziso zvisikwa uye mhindumupindu.

The remagineti simba

Zvingaonekwa zvakaratidza kuti mumakore 1,400 apfuura, kuti simba remagineti yedu dzakawira kaviri. unogona kugadzira nyore kukarukureta pamusana mashoko akadaro, izvo zvinoratidza kuti nemakore Pasi haasi anopfuura 10 zviuru. makore.

"Pierce" nyika akaturikidzana. Marasha, peat uye mafuta

Kazhinji mumidziyo zvikamu zvinogona kugumbura pamusoro vertically dzinongoda hunde dzacho miti, uyewo nezvimwe zvicherwa, "rakapinza" multiple akaturikidzana enyika. Izvi zvinoratidza kuti mafashamo auya rikanyuramo miti rhizome pasi.

Zvinokosha kucherechedza kuti vakawanda aripo chicherwa mari ndiwo chigadzirwa nerwizi. Saka marasha, mafuta uye peat anoratidza njodzi yakakura. Zvino, uye zvakawanda - ndiye Organic, waiva panzvimbo imwe uye nekuumbanidzwa pasi pokudzora tembiricha uye kumanikidzwa. Zvakaoma kufungidzira kuti akasikwa kwemakore akawanda. Asi aigona kuva mafashamo guru kuti akaita miti, uswa uye nezvimwe zvinhu zvipenyu kuunganidza pane imwe nguva, apo vakanga kugeza pamwe inorema matombo uye runonditsikirira guru muviri mvura.

washout

Masayendisiti anodavira kuti kana makore Pasi ari mamiriyoni, pose panyika akanga kubata wegungwa sezvo Earth pasi pokudzora mvura zvishoma nezvishoma kushambidzwa mugungwa, pova chinhu chakadai kuondomoka. Zvino sei munyanza ari 3,6 chete% munyu, nokuti mamiriyoni emakore inonaya zvose zvakanga kushambidzwa kure mumvura miviri?

Muchadenga kunoongorora kutanga US chitundumusere-musere zvakakomba kunetseka kuti vanogona kurasika ari meteoric muguruva, kubva maererano kazhinji akagamuchira dzidziso dzidziso Romwedzi yakaumbwa maviri kana matatu bhiriyoni apfuura, panguva imwe chete Panyika. kubvuma Izvi zvakaita kuti zvakakwana musoro kubvuma ndechokuti musi Earth ari Satellite akaita vaunganidza guru yakawanda nzvimbo guruva. Asi asvika muchadenga kunoongorora vakaona chidukuduku rukoko guruva. Masvomhu zvakaratidza kuti nemakore mwedzi havagoni kusapfuudza mucherechedzo 10 zviuru. Years.

Low zviri nehelium

Zvinonzi akaratidza kuti nedanho kuora kuti uranium exchange vakawana nuclei ose nehelium uye kutungamirira. Huwandu nehelium chaibwinya mumhepo, - 300 zviuru matani pagore .. To musi, wakaratidza kuti zvomumhepo izere zvishoma kupfuura 3 bln. Matani nehelium, izvo zvinoratidza kuti nemakore Pasi ungangova kusapfuudza muzariro 10 zviuru. Years.

Dinosaurs - zvapupu zvakanaka

Mapfupa zhinji dainoso zvisaririra vasati vakatendeukira ibwe. Nokuda kwavo anokosha ukobvu, hazvina zvichida kuva chiuru mashoma makore kupedza mineralization. Dzimwe mapfupa akasangana vakasara nyoro zvinyama uye masero kunyange matsvuku. Uyewo, pane zvakawanda mifananidzo siyana mhando dinosaurs, zvokutemerwa cobbles uye matombo, izvo zvinoratidza kuvapo vanhu iyoyo. Nei masayendisiti hazvibvi pfungwa yake kuti dinosaurs akararama mamiriyoni emakore akapfuura, uye kuramba vanoti Earth ane makore anopfuura bhiriyoni imwe?

Souchapupu hwokuti, isu kuyeuka zvakawanda nyaya uye ngano, raisanganisira makava. Ungangove, kuti sezvo makava izvi zvishoma nezvishoma pangozi mhando dinosaurs.

Chokwadi, kune vakawanda zvakasiyana uchapupu nezvokuti makore ari Nyika haigoni kuva mabhiriyoni emakore. Uyezve, vakawanda nesayenzi nekusimba zvinhu pamusoro akafanana zvakanyorwa muBhaibheri. Asi panguva iyi vaongorori mumagazini ino haisati kukwanisa kupa zvakawanda kana zvishoma kongiri mhinduro yomubvunzo uyu, sezvo pasina ruzivo rwokugadzira ano kana pfungwa dzakasiyana-siyana regai kupa mukana wakadaro.
