Mayelana kwezwe elisizungezile: siphi isimo kuyinto Ngomhlaba?

ukubukwa Astronomical sonke isintu kwakhiwa emakhulwini. Kusukela eGibhithe lasendulo nempucuko mhlawumbe ngisho ngaphambili, abacwaningi wathumela ukubukeka eziya esibhakabhakeni, uzama ukufunda ulwazi oluningi mayelana nesakhiwo zezwe lethu. Nesithakazelo Yiqiniso, ukuma nosayizi Zomhlaba.

Kusukela ngaleso sikhathi, engike phambili eziningi. amaqiniso Enough manje singasho ngokuqinisekile.

Futhi omunye le mibuzo: siphi isimo kuyinto Ngomhlaba? Umlando ezihlukahlukene imibono mayelana ukuma unozungezilanga wethu ube eside futhi ethakazelisa kakhulu. Yena zikleliswe amadoda ihlonishwe ososayensi besikhathi sethu, Ephakathi futhi endulo. Ukuze iqiniso (lowo wanamathela kuwo) babeshushiswa ngisho wafa. Kodwa iqiniso bayazi akwaliwa.

Futhi manje ngalokho ijamo eMhlabeni has ekilasini esikoleni 4 ukusho la mazwi ngokuqiniseka okugcwele.

Masikhumbule ukuthi empeleni izinto amafomu ekhaya lethu iplanethi.

Ukuma Umhlaba

Ekhulwini leminyaka eledlule, abantu uye wakwazi ukwenza eqa omkhulu phambili: ukwethula mkhathi ngowokuqala isikhala ezikude enikeziwe. Labo alethwe (wathumela) Usosayensi isithombe iplanethi. Kwakuyisikhathi enhle eluhlaza nendikimba ethile esemkhathini, kodwa ifomu izimo izichibiyelo.

Ngakho, ngokusho, ulwazi olusha eziqinile mayelana iplanethi, siyazi ukuthi Umhlaba uyindilinga eyisicaba kancane kuma-pole. Okungukuthi, akuyona sphere kodwa ellipsoid ayenawo, noma geoid. Kumelwe ukhethe phakathi nale migomo amabili asemqoka kuphela isayensi yokuma kwezinto ezisemkhathini, geodesy, Aerospace. Inkulumo wenombolo nemingcele planethi kuzodingeka ukuba izibalo ezinembile. Bese ukuma umhlaba izici zayo siqu.

incazelo kwamanani ukuma iplanethi

Ukuze isigaba ulwazi olujwayelekile mayelana nezwe ngaphezu kokuba kwenza ukusebenzisa geoid eside. Lesi sakamuva, ngasendleleni, kusukela esiGrekini ngokwezwi nezwi lisho "into efana Earth."

Kuyathakazelisa ukuthi ukuchaza izibalo ukuma Umhlaba njengenhlangano ellipsoid ayenawo akunzima. Kodwa njengoba geoid kuyinto kunzima ukuthola idatha olunembile kunazo kuyadingeka ukukala amandla adonsela phansi ezindaweni ezahlukene iplanethi.

Kungani Umhlaba isicaba-pole?

Kulokhu okungenhla manje sifuna sixoxe ngezinye zezici ezithile yonke indaba ephathwayo. Manje njengoba siyazi ukuthi ijamo eMhlabeni has eqinisweni, kuyoba mnandi ukubona ukuthi kungani.

Nalapha: iplanethi yethu uyindilinga eyisicaba kancane kuma-pole, futhi akuyona sphere ephelele. Kungani becabanga kanjalo? Impendulo ilula, kusobala kunoma ngubani ine ukuqonda sokuqala physics. Lapho Umhlaba uzungeza emhlabeni axis awo e yenkabazwe kukhona amabutho centrifugal. Ngakho, nezigxobo zabo akukwazi. Benziwa umehluko lo engaba bhé elimboze izindawo ezibandayo kanye: Okokugcina eside endaweni ethile km 50.

Umzila wokuzungeza Umhlaba: siphi isimo kuyinto?

Njengoba sazi, iplanethi kwakwenziwa hhayi kuphela emhlabeni axis awo, kodwa futhi kwenza uhambo olude emhlabeni osenkabeni yesimiso sonozungezilanga. Ingabe line iplanethi ngalo ihamba emkhathini, ngokuthi emzileni. Siye safunda, siphi isimo kuyinto iplanethi ewumhlaba. Futhi ngathola ukuthi uthenge ke kusukela ngokushintshana.

Kodwa lokho ifomu owenza orbit eMhlabeni? Wenza uzungeza ilanga e endleleni okweqanda, ngokuba ngezikhathi ezahlukene at amabanga ehlukene avela elangeni. Lokuba ingxenye ethile ye-orbit incike isizini emhlabeni.

State lapho ibanga iplanethi okuvela elangeni, ngokuthi aphelion, iwukuphela ke - perihelion (amagama amabili Lokudabuka ngesiGreki).

Imidwebo impucuko yasendulo

Ekugcineni kukhanye sihloko bright izithombe zethu nemicabango siye echazwe bakaCharles impucuko yesimanje. Fantasy kuzo, kumele wathi, mnandi.

Ephendula umbuzo othi "Hlobo luni ukuma kuyinto Emhlabeni?" kwaseBhabhiloni lasendulo bangase baphikise ngokuthi kuba entabeni omkhulu owodwa ngaphansi kwemithambeka okuyinto ezweni labo. Ngenhla kuba Dome - esibhakabhakeni, futhi kwakunzima njengoba edwaleni.

AmaNdiya ayeqiniseka ukuthi umhlaba uhlezi phezu izindlovu ezine, elibamba ufudu emhlane wakhe, elintantayo olwandle ubisi. Isiqondiso zezinhloko izindlovu - amaphuzu amane yekhampasi.

Kuphela BC 8-7 leminyaka. e. abantu kancane kancane ukuba afinyelele isiphetho sokuthi umhlaba - into ehlukile kuzo zonke izinhlangothi, hhayi indawo omi lutho. Kuye ebusuku utshelwa ukunyamalala ilanga, phambi okuyinto lwavivinywa nangokuthuthumela.

isiphetho

ukukhuluma Cishe, Earth - round. Ukuze ongelutho lokhu kuyoba okwanele, kodwa hhayi sencazelo isayensi. Ngo geodesy, Aerospace, isayensi yokuma kwezinto ezisemkhathini udinga idatha lunembile izibalo. Futhi lapha kuyasiza impendulo ngqo embuzweni, yini ifomu owenza Earth. Futhi geoid noma ellipsoid zokuvukela umbuso. Planet ngaphansi kwethonya amabutho centrifugal isicaba-pole. Cabangela idatha eqondile emhlabeni kubalulekile ukuthola izibalo lesifanele.

Long gone izikhathi lapho umhlaba kunikelwe emuva noma amelwe Izindlovu ubuso bayo flat. Ake abazinikele e iqiniso mayelana nezwe kanye sihlala uyakufanelekela isikhathi sabo!
