Inkathi umhlaba

Kwelinye amakhona yonke izigidi zeminyaka edlule, kuqhuma ibhomu kakhulu ngemva. Ngenxa yalokho inkanyezi ukushaqeka, sekuyisikhathi eside aqhubeka ephila ngemva kwakhe, waba njengomama ifu elikhulu. It baphotha emhlabeni futhi ababhubhise izinsalela umzimba eshubile. Izigidi iminyaka angajwayelekile amandla athile angabonakali bemvelo bakhangwa izinhlayiya lwamafu, kanjalo zakha isimiso ibhola. A new nendikimba ethile esemkhathini is ohlangene e isimo sawo futhi iba omkhulu ngokwengeziwe. ingcindezi ezingakaze zibe khona. maphakathi ezingeni abasa umlilo, okwakubekelwa ayisekho ukuyikhokhela. Lokhu ilangabi esinamathambo kulowo umzimba wonke - ngakho nje ilanga wazalwa. Kusukela izinsalela izinkanyezi efile kwakhiwa ngokuhamba kwesikhathi namabhola-iplanethi.

Ngaphambi ekuqaleni kwenkathi yokuqala loMhlaba isakhiwo kwakuhluke kakhulu okuxekethile okuxekethile, usayizi umkakhe sasisikhulu ngisho kunalokho of kwelanga. Ngokuhamba kwesikhathi, ohlangene ibhola futhi yaqala ukuba nomusa, kodwa ke ubuso bayo is selehlile. Ngaphambi sebekwazi indiza emkhathini, kwakungenakwenzeka ukulinganisa ngisho eseduze engu-Earth, kanye amasampula kusukela enyangeni, okuyinto ubhekwa engu efanayo iplanethi zethu ayebonisa ukuthi ekuqaleni komlando sokuthuthuka sabekwa eminyakeni 4-4.6 billion edlule. kwezazi abadumile ngesikhathi wadala ekhethekile wokubalwa kweminyaka ngamadwala isikhathi embulungeni, okuyinto, empeleni kuyinto indaba yokudalwa kanye nokuthuthukisa ukuphila kule mbulunga enguMhlaba. Lokhu isikali babuhlukaniswe izinkathi kanye nobudala Zomhlaba, ubude kwabanye ku-emakhulwini ezigidi zeminyaka.

Archaea. Kwaba futhi kule nkathi yaqala ukuvela eMhlabeni. Uthi kwaphela iminyaka emibili nengxenye billion, lo iplanethi selehlile futhi camera nge okuqinile itshe uqweqwe, mpilo emkhathini. Lapho izinga lokushisa ifinyelela degrees engamakhulu Celsius, isibhakabhaka some amafu aminyene futhi imvula enkulu. Ngemva kwalokho, phezu kobuso wonke babe ezilwandle nakuzo olwandle, lapho ukuphila kwaqala kamuva - amaseli ezincane ezingaba ukukhulula umoya-mpilo.

Proterozoic. Landela inkathi Archean Zomhlaba isikhathi esingaphezu lihlotshaniswa izinto eziphilayo. Ngo izikhathi Proterozoic avele eziphilayo ezinamangqamuzana amaningi. eziphilayo owumphumela yahlanganiswa, lakhula ngosayizi futhi yakha i-nucleus futhi ulwelwesi. Kuneminye lwezinhlobo ezahlukene ukwakhiwa isakhiwo yezinto eziphilayo.

PALEOZOIC. Ezikhathini Paleozoic waqala ukuthuthukiswa esebenzayo phakathi komhlaba ngokwehlukanisa eziphilayo zasolwandle. Lesi sigaba lahlukaniswa ososayensi ngoba nangenkathi eyengeziwe noma izinkathi, okuyinto wenza sikwazi ukufunda ngokuningiliziwe.

ECambria. Era is more ngokuthi "ukwanda kokukhiqizwa lwamathambo" ezaziwayo. Futhi Wenziwa akusilo ize, ngoba ngaleso sikhathi eziphilayo ezikhona atholwe amathambo okuqinile, kanye spikes, "izindlu" zabo futhi amagobolondo.

Ordovician. Ngalesi sikhathi, waba ngukumkani izidalwa ngubani ukude owawufana nawofezela yesimanje futhi izicabucabu ezinobuthi. shellfish encane futhi uvele. Kodwa impumelelo ebaluleke kakhulu kulesi sikhathi - ukuvela ezilwaneni ezinomgogodla, ikakhulukazi - chordates.

Silurian. Kwabe sekuqala inkathi entsha kwaphawulwa ukuguqulwa inhlanzi, ulwelwe, kusale kolwandle, ezweni ukubukeka izimila emadwaleni.

Devon. Izazi eziningi ziye ngokuthi le nkathi "umbuso inhlanzi." kwemvelo okuqhubekayo kanye nokuqukethwe eziphilayo ezihamba ezweni.

Carbon. Dawn of yezimila nezilwane ezihlukahlukene: zonke wakhula oluhlaza, akujabulela. Kwakukhona okhokho AmaConifers lanamuhla. Izinambuzane yingcweti emoyeni. Abanye babo baba usayizi omkhulu: isibonelo, kwenkululeko dragonfly amaphiko akwazi ukuxoxa ngamamitha amabili.

Perm. Perm - ezingwadule namandla khulu leminyaka. Phakathi nale nkathi, Pangea kwamiswa.

Inkathi Earth esifundweni sawo evumela ngamunye sazi umlando umsuka izwe lethu eliyingqayizivele bemvelo, ukuphila, nokuthuthukiswa kwazo zonke orgasms emhlabeni. Umlando iplanethi yethu - kuba oluyimfihlakalo kunalo lonke konke okukhona namuhla, futhi uma wazi imithetho yayo, kungenzeka ukuthola okuningi ezithakazelisayo futhi ezingalindelekile.
