About nyika yakatipoteredza, chii chimiro ndiye Earth?

Astronomical maonero vanhu vose kuumbwa pamusoro emakore. Kutanga kubva muIjipiti yekare uye zvichida kunyange kwokutanga kwenzanga vaongorori akatumira Kutarira kudenga, vachiedza kudzidza zvakawanda nemamiriro edu nyika. Vanofarira Chokwadi, chimiro uye ukuru Earth.

Kubvira ipapo, hatina vaenda mberi zvikuru. Enough zvinhu zvino tinogona kutaura kuti chokwadi.

Uye mumwe wemibvunzo iyi, chii chimiro ndiye Earth? Nhoroondo zvakasiyana siyana mazano pamusoro pezvakaita nyika yedu refu uye anonakidza zvikuru. Iye yabuda varume vairemekedza masayendisiti nguva yedu, kuMiddle Ages uye kare. Nokuti chokwadi (uyo rakanamatira kwavari) vakanga vachitambudzwa uye kunyange akafa. Asi chokwadi vanoziva haina akaramba.

Zvino chii chimiro Pasi ane 4 kirasi yechikoro kutaura nechivimbo chakazara.

Ngatikurukurei kuyeuka sei chaizvoizvo zvinhu pamwe marudzi musha redu.

Maumbirwe Earth

Muzana remakore rapfuura, vanhu vakakwanisa kuita achikwakuka huru mberi: kuti nokuparura chitundumusere-musere wokutanga pazvakaringana kure yakapiwa. Avo vakauya (akatumwa) musayendisiti photos nyika. Yakanga yakanaka mutema yokudenga muviri, asi chimiro zvave zvimwe yakabvumira kugadziriswa kwemutemo wekuita.

Saka, maererano itsva, ruzivo akavimbika pamusoro nyika, tinoziva kuti nyika zvishoma flattened matanda. Ndiko, haisi nzvimbo asi ellipsoid chimurenga, kana geoid. Kusarudza pakati mazwi maviri aya kunokosha chete zvokuongorora nyeredzi, nyika, geodesy, Aerospace. Kusanganiswa mashoko yepasi wacho parameters vachava zvakafanira kuti Masvomhu yakarurama. Zvino panguva pezvakaita nyika ine peculiarities ayo.

tsananguro kusanganiswa pamusoro pezvakaita nyika

Nokuti Chikamu vakawanda ruzivo pamusoro nyika kupfuura kushandisa izwi geoid. Yokupedzisira, nenzira, kubva rechiGiriki sezvariri rinoreva "chinhu chakafanana Earth."

Zvinofadza kuti anorondedzera mathematically chimiro Pasi sechinhu ellipsoid chimurenga hakuna kuoma. Asi sezvo geoid zvisingaiti kuwana yakarurama kwazvo mashoko zvakafanira kuyera giravhiti panguva dzakasiyana pfungwa panyika.

Nei Nyika iri flattened ari matanda?

Kubva apa tava kuenda funga zvimwe dzakananga zvinoumba yose dingindira. Zvino kuti tizive chii chimiro Pasi ane chokwadi, zvichaita zvinonakidza kuona sei.

Zvakare: redu iri flattened zvishoma panguva mapango, uye haisi nzvimbo yakakwana. Sei zvakadaro? Mhinduro iri nyore, pachena kuti munhu ane kutanga kunzwisisa wefizikisi. Kana Pasi rotates kumativi akabatana yayo neequator pane Centrifugal masimba. Saka, matanda avo havagoni kuva. Uye akaumba musiyano iri nharaunda iri polar uye ine: Ruriko yakareba kumwe muna 50 km.

The muchadenga Nyika: chii chimiro iri?

Sezvatinoziva, nyika inotenderera ayo akabatana kwete chete, asi kunoitawo rwendo rurefu kunhivi nepakati renzou. Ko zvekufungidzira mutsetse pamusoro icho uchifamba muchadenga, akadana muchadenga. Takadzidza, chii chimiro ndiye Nyika. Vakawanawo kuti watengwa kubva kutenderera.

Asi chii chimiro anoita muchadenga paNyika? Iye ari kuita kumativi zuva elliptical nzira, kuva nenguva dzakasiyana panguva dzakasiyana kure zuva. Of ari muchikamu imwe yacho muchadenga kunobva mwaka panyika.

State apo nyika kure kubva zuva, akadana aphelion, kunogona chinhu pazviri - perihelion (mashoko maviri echiGiriki mavambo).

Mifananidzo mararamiro ekare

Pakupedzisira chiedza chedu nyaya yakajeka mifananidzo fungidzira kuti tava vanorondedzerwa vamutangira yebudiriro ano. Fantasy kwavari, inofanira akati, ndafara.

Wokuti "Imhandoi chimiro ndiye Earth?" rekare reBhabhironi vangati kuti gomo guru pamusoro rimwe mujinga inova nyika yavo. Pamusoro ndiwo nzvimbo - denga, uye zvakanga zvakaoma sedombo.

The maIndia nechokwadi kuti nyika anoisa pamusoro nzou ina, iyo chinobatanidza hamba kumusana kwake, akayangarara ari mugungwa mukaka. Kutungamirirwa vakuru nzou - mana pfungwa chinongedzo.

Chete 8-7 remakore BC. e. vanhu zvishoma nezvishoma vakasvika pakugumisa kuti nyika - chinhu takaparadzana kumativi ose, uye kwete okumisa chinhu. Kwaari usiku hwoga hwoga chakakurudzira Kutsakatika kwezuva, pamberi iyo akaedzwa kushamiswa.

mhedziso

Nehasha kutaura, Pasi - kumativi. Kuti munhuwo zvake uyu achava zvakakwana, asi kwete tsanangudzo nesayenzi. In geodesy, Aerospace, zvokuongorora nyeredzi, nyika vanoda mashoko akarurama nokuda Masvomhu. Uye pano rinobatsirawo kuti mhinduro chaiyo kune mubvunzo, chii chimiro anoita Earth. Uye geoid kana ellipsoid chimurenga. Planet pasi pokudzora Centrifugal mauto flattened matanda. Kufunga chairo mashoko panyika kunokosha kuti zvakarurama Masvomhu.

aenda Long nguva apo pasi akapa kuna musana kana dzinomiririrwa nzou ayo sandara penyika. Ngatikurukurei vagadzwe chokwadi pamusoro nyika uye isu kuramba akakodzera nguva yavo!
