Nyengo - dongosolo limafotokozera. Kodi chi?

Nyengo - ndi lalikulu nyengo, nthawi zakale. Chotero anaitana dongosolo la nthaŵi, komanso chiyambi cha nyengo iyi. Mbiri ya dziko lathu zikhoza kugawidwa m'mbali. Pakati pawo, iwo amasiyana zina nyengo komanso malo kusintha, komanso yojambula kwambiri pa chitukuko cha moyo nyama ndi zomera. Ambiri amachita chidwi, kodi msinkhu ndi likuimira. Magawo chachikulu cha chitukuko cha Dziko Lapansi.

nyengo archean

Panthawi imeneyi, dziko lathuli linapangidwa, nthawi unatha pafupi zaka mabilioni. Moyo Padziko Lapansi sizinakhale, mu nyanja ya mmene zinthu zosiyanasiyana zimachitikira pakati zidulo, alkalis, salt. nyengo Archean limene lachititsa chinthu mapuloteni. Zinali ndiye amene anayamba kutuluka zamoyo.

nyengo proterozoic

Ikulu nthawi nthawi ya dzikoli, umene unatha 2 biliyoni zaka. Panthawi imeneyi, kukhala algae ndi mabakiteriya, tizilombo tikhale matupi awo, iwo multicellular. Nyengo - ndi nthawi pamene pali chinthu chatsopano, Proterozoic siteji wolemekezeka mtundu wa miyala ya zitsulo. Nthawiyi amakhala ndi mfundo yakuti njira zonse moyo chichitike m'nyanja.

Palaeozoic

Ino ndiyo nyengo kusiyana kwa kusintha okhazikika mu zikhalidwe nyengo, kuti lagawidwa magawo 6. Panthawi imeneyi, osauka nyama ndi zomera, pali mitundu ya nsomba. M'mphepete kukula conifers, Mumapezekanso. Padziko pakati pa chi anali achule choyamba ngati zokwawa, kafadala, ziwala. nthawi amakhala ndi kusokonekera zonse, kusintha mosiyanasiyana wa dziko lonselo.

Nyengo Mesozoic

Gawo ongokhala Triassic, Jurassic ndi nthawi Cretaceous. The Mesozoic nyengo - ndi zikamera wa dziko ndi nyanja akamba, achule, nkhanu, mtundu watsopano wa miyala yamtengo wapatali. Chimakhala chogwidwa ndi zokwawa ndi zinyamazi. Mu zaka pakati pali oimira woyamba wa mbalame ano ndi tizilombo. The nthawi Cretaceous anali kutha kwa pterosaurs ndi zinyamazi.

Panthawi imeneyi, mikhalidwe nyengo, ndi chifukwa kuti dziko yokutidwa ndi greenery. Pa dziko pali mitundu woyamba wa paini ndi paini mitengo ndi zomera maluwa. Masiku Mesozoic ayamba kugwirizana tizilombo ndi zomera. Nthawi imeneyi, lonselo kutenga njira yatsopano ndi miyeso, zilumba anapanga chifukwa cha kugawanika kwa. Atlantic Ocean zikuchulukirachulukira kukula, madzi anasefukira timapepala lalikulu la dziko.

nyengo Cainozoic

"Kodi zaka zambiri otsiriza nthawi imene anthu apulumuke?" - zambiri kumatanthauza funso ili anthu. The Cenozoic nyengo (udzakhala kwa tsiku lino) unayamba pafupifupi miliyoni 66 zapitazo. Ndi kusiyana pakati pa Kubwera kwa mbalame ano, nyama, angiosperms ndipo, ndithudi, anthu. Ndi pakati pa chi wapanga pafupifupi magulu waukulu wa maufumu a chilengedwe. Pa nthawi iyi pali steppes ndi meadows, mitundu yatsopano ya udzu, zitsamba. Komanso mu chikhalidwe anapanga waukulu mitundu agrocenoses ndi biogeocenosis. Munthu amayamba atengere chilengedwe, ntchito chikhalidwe kukumana ndi zosowa munthu. Ndi anthu amene pambuyo pake anasintha dziko organic. The Cenozoic Nyengo lagawidwa atatu nthawi: Paleogene, Neogene ndi Quaternary. Chikudziwikabe lero.

Akuti nyengo olekanitsidwa ndi makhalidwe nyengo komanso malo. Koma pali machitidwe ena a limafotokozera. Mwachitsanzo, kunena kuti "nthawi yathu ino" anthu ambiri kumafuna sitepe chimene chimachokera kwa Khirisimasi. Komanso, anthu amakhala pa mafakitale, technotronic ndi ena nthawi kuti chinachake wolemekezeka, asintha mmene anthu za dziko, anasintha maganizo kuti zamoyo.
