Era - muronga hurongwa. Ndezvipi yaitonga?

Era - huru nguva pfupi, munhoroondo kumwedzi. Saka akadana Tsika dzenguva, uyewo pakutanga yaitonga ichi. Nhoroondo yedu inogona kukamurwa nguva. Pakati pachavo, havana zvisingapindirani zvimwe kuchinja okunze uye nenzvimbo, uyewo chinokosha budiriro kukura mhuka uye chirimwa upenyu. Vakawanda vanofarira, ndedzipi zera uye chii dzinomirira. The chikuru zvokukura kukura Nyika.

archean panguva

Panguva ino, nyika yedu rakaumbwa, nguva yakatora anenge mabhiriyoni makore. Upenyu Panyika asina, mugungwa nemakemikari pakati acids, alkalis, munyu. Archean nguva akapa pave puroteni fuma. Panguva iyoyo yakatanga kubuda zvipenyu.

proterozoic panguva

Huge nguva munguva yepasi, urwo rwakatora anenge mabhiriyoni 2 years. Panguva ino, kuva algae uye utachiona, zvinenge wana miviri yavo, vanova zvipuka zvine masero akawanda. Era - imwe nguva nguva kana paine chinhu chitsva, Proterozoic Danho aikudzwa chimiro deposits ose simbi esimbi. Nguva iyi kunoratidzwa ndechokuti zvose pezvakaitwa upenyu kuitika munyanza.

Palaeozoic

Ndiyo nguva musiyano pakati zvachose Kuchinja kwemamiriro okunze, rakakamurwa 6 nzendo. Panguva ino, dzichiri kasvisto uye miti nemhuka zvakazonaka, pane mhando dzakawanda hove. Pamahombekombe vanokura Conifers, ferns. Around pakati yaitonga vaiva amphibians vokutanga sezvo zvinokambaira, zvipembenene, mhashu. Nguva kunoratidzwa kugara nenyonganyonga, kuchinja Zvekare zvimiro zvemhashu zvakaita makondinendi.

The Mesozoic panguva

Danho rine Triassic, Jurassic uye Cretaceous nguva. The Mesozoic Nguva - ndiyo chidzoke nyika uye gungwa nenjiva, matatya, kuti shrimp, itsva mhando matombo ekorari nokure. Chiri hunodzorwa zvinokambaira uye dinosaurs. Pakati zera pane vamiririri shiri ano uye nezvipembenene vokutanga. The Cretaceous nguva yaiva kutsakatika pterosaurs uye dinosaurs.

Panguva ino, nani okunze, zvokuti nyika akafukidzwa greenery. On nyika pane mhando vokutanga nemisipiresi uye vanoondoroka miti, uye maruva zvirimwa. Mugore Mesozoic yaitonga vari kutanga pamwe zvipembenene kasvisto. Panguva iyi, makondinendi kupfeka matsva siyana uye kukura, zviwi zviri aumba somugumisiro vanorambana. Atlantic Ocean ari kuwedzera kukura, ichizadza maturakiti huru panyika.

Cainozoic panguva

"Makore mazhinji sei okupedzisira nguva iyo vanhu upenyu?" - kazhinji rinorondedzerwa ichi mubvunzo vanhu. The Cenozoic yaitonga (nayo rinovapo kusvikira nhasi) akatanga anenge mamiriyoni 66 apfuura. It akasiyanisa veMubatanidzwa ano shiri, mhuka, angiosperms uye, chokwadi, vanhu. Pakazosvika pakati yaitonga akaumba huru mapoka poushe zvakasikwa anenge zvose. Panguva ino pane steppes uye Mafuro, mhando itsva rekushongedzesa, nemiti. Uyewo zvakasikwa akaumba huru mhando agrocenoses uye biogeocenosis. Man anotanga kuchinja zvakatipoteredza, kushandisa zvisikwa kusangana pachedu zvinodiwa. Zviri vanhu pashure achinja makemikari nyika. The Cenozoic Era rakakamurwa zvitatu nguva: Paleogene, Neogene uye Quaternary. It mberi nhasi.

Vaiona panguva dzakaparadzaniswa okunze uye nenzvimbo maitiro. Asi pane dzimwe mugadziriro nguva. Somuenzaniso, achiti "nguva yedu", vakawanda kungandipa danho rwakatanga kubva Christmas. Uyewo, vanhu akaisa vakagura maindasitiri, technotronic uye dzimwe nguva kuti chinhu anokudzwa, zvakachinjwa nzira vanhu kufunga nyika, akachinja mafungiro kuti zvipenyu.
