Era - Nidaamka taariikhiyan ah. Waa maxay xilligii?

Era - waa muddo waqti badan oo, muddo taariikhi ah. Sidaas loo yaqaan nidaamka of taariikhda, iyo sidoo kale bilowgii Zaman this. Taariikhda dhulkeenna loo qaybin karaa waqti. naftooda u dhaxaysa, waxay ku kala duwan yihiin isbedelka cimilada qaar iyo juquraafi, iyo sidoo kale horumar la taaban karo horumarinta nolosha xayawaanka iyo dhirta. Qaar badan ayaa xiiso u qabta, waxa ay yihiin da'da iyo waxa ay u taagan yihiin. Marxaladaha ugu muhiimsan ee horumarka ah ee dhulka.

Zaman archean

Wakhtigan, dhulkeenna, waxaa la sameeyay, muddo socday oo ku saabsan a billion sano. Life on Earth mid aan jirin, in badda ee falgalka kiimikada dhexeeya acids, alkalis, cusbada. Zaman Archean siiyey kor u qaada walax protein ah. Waxay ahayd markaa in bilaabay inuu soo baxo noolaha.

Zaman proterozoic

muddo duration weyn ee caalamka, taas oo socotay ilaa 2 bilyan oo sano. Wakhtigan, horumarinta algae iyo bakteeriyada, noolaha ay u bartaan jidhkooda, ay u noqdaan multicellular. Era - waqtiga marka ay jirto wax cusub, Proterozoic stage foomka Sharaf ah kayd ah iron ore. Xilligan waxa lagu gartaa xaqiiqada ah in dhammaan geedi socodka nolosha ka dhacaan meel badda.

Palaeozoic

Tani waa kala duwan yihiin muddo isbeddelka joogtada ah ee cimilada ah, waxay u qaybsan yahay 6 marxaladood. Wakhtigan, horumarinta dhirta iyo ugaarta, waxaa jira noocyada badan ee kalluunka. Dhinacyada bangiyada koraan fiiqfiiqan, ferns. Qiyaastii dhexe ee xilligii ahaayeen lafdhabarka ugu horeysay sida xamaarato, kuwa lamid ah, kabajaan. Muddada lagu gartaa isbedelka joogto ah, beddelo qaababka of qaaradood ah.

Xilligii Mesozoic

Wajiga kooban Triassic, Jacka iyo muddooyinka Cretaceous. Xilligii Mesozoic - waa ah ee dhulka iyo badda qoolley, xataa rahyo, haley, noocyada cusub ee shacaab. Dadwaynaha xamaarato iyo dinosaurs. In da'da dhexe waxaa jira wakiilada ugu horeysay ee Shimbiraha oo casri ah iyo cayayaanka. The muddo Cretaceous ahaa eynu ee pterosaurs iyo dinosaurs.

Wakhtigan, hagaajiyeen xaaladda cimilada, oo sababtay in dalka la daboolay Ereyada. On dalka, waxaa jira noocyada ugu horeeyay ee geed tirsah ah iyo geed dhirta, iyo dhirta ubax. In xilligii Mesozoic ah ayaa bilaabay in ay iskaashi cayayaanka iyo flora. Muddadan, qaaradood qaadan on foomamka iyo cabbir cusub, jasiiradaha loo sameeyay ay sabab u tahay kala qaybsanaanta. Atlantic Ocean sii kordhaya ee size, daad, goobo badan oo dalka.

Zaman Cainozoic

"Imisa sano muddo la soo dhaafay, taas oo nolosha aadanaha?" - inta badan su'aashan dadka lagu qeexay. The Zaman Cenozoic (waxay soconaysaa ilaa maantadan la joogo) bilaabay oo ku saabsan 66 milyan oo sano ka hor. Waxay kala duwanaayeen dhalashada ee Shimbiraha oo casri ah, nuujiya, angiosperms iyo, dabcan, aadanuhu. By dhexe ee Zaman ayaa la sameeyay ku dhowaad dhammaan kooxaha ugu weyn ee boqortooyooyinka dabiiciga ah. Wakhtigan waxaa jira deel iyo seeraha, noocyo cusub oo cows, ku xoortay. Sidoo kale ee dabiiciga ah sameeyay ugu weyn ee noocyada agrocenoses iyo biogeocenosis. Man bilaabaa inuu la qabsado deegaanka, si ay u isticmaalaan dabiiciga ah si loo daboolo baahida shakhsiyeed. Waa dadka dambe dunida organic bedelay. Cenozoic Era wuxuu u qaybsan yahay saddex muddo: Paleogene, Neogene iyo Quaternary. Waxaa maanta.

Waxaa loo tixgeliyaa xilli kala sifooyinka cimilada iyo juquraafi. Laakiin waxaa jira habab kale oo ka mid ah taariikhda. Tusaale ahaan, isagoo leh "our Zaman", dad badan oo ku lug tallaabo taas ka Christmas billaabay. Sidoo kale, dadka dhigay off warshadaha, technotronic oo kale muddo ah in ay wax distinguished, isbeddeleen sida dadka ka fikir dunida, habdhaqanka bedelay in noolaha.
