Axis Umhlaba kaThixo - oku kubalulekile sezulu umhlaba lethu

axis Planet Earth xa kumda wesangqa langasentla kongomisiwaka eka kwindawo apho ixabiso lesibini inkwenkwezi, ekuthiwa ekwincamzwe, xa inxalenye ngasemva ye lekroza Minor Dipper.

Le nkwenkwezi icacisa emini kwi intetho yentshukumo isangqa encinane malunga 50 kwemizuzu radius arc.

Kumaxesha amandulo wayesazi ukuthambeka of axis Yomhlaba

A kudala, kwi-BC kwinkulungwane II. e., i ngeenkwenkwezi Hipparchus wafumanisa ukuba eli nqanaba zexabiso ezinokususwa kuzo nesibhakabhaka esimnyama, kwaye kancinane siya intshukumo kwelanga. Wabala ngesantya intshukumo kwi °-1 ekhulwini ngalinye. Le kwafunyanwa kuye ngokuba "precession of ongu Yomhlaba." Oku intshukumo phambili, okanye nobusuku. Ixabiso ngqo kwesi siphakamiso, njalo precession, lingana imizuzwana-50 ngonyaka. Ngenxa yesi sizathu, umjikelo opheleleyo we baza kuya kuba malunga 26.000 yeminyaka ubudala.

Ukuchaneka kubalulekile ukuba isayensi

Makhe sibuyele umbuzo malunga esibondeni. Icacisa indawo yayo ngqo phakathi kweenkwenkwezi - ngomnye wemisebenzi ebalulekileyo astrometry, esingethe umbandela imilinganiselo jike kwaye angles kwi intetho yentshukumo ukujonga imvelaphi leenkwenkwezi neleeplanethi, ukuthabatheka ezifanelekileyo kunye nemigama ukuba iinkwenkwezi, kwakunye ngesisombululo iingxaki ngeenkwenkwezi ezenziwayo, kubalulekile ukuba geography, geodesy lokuhambisa.

Fumana indawo kwipali yasezulwini, ungasebenzisa iifoto. Khawucinge elide-focus camera yokuthathwa Kwaqaliswa njengoko astrograph ejoliswe cwaka kwindawo wezulu kufuphi zezibonda. On emifanekiso enjalo, inkwenkwezi nganye ichaza isetyhula arc ngaphezulu okanye ngaphantsi elide kunye kwiziko olulodwa, yaye sisiphi ipali yehlabathi - indawo apho axis umhlaba ujikeleza ngqo.

Ezimbalwa engile ukuthambekela axis neeNdawo

Lo moya kweikhweyitha yasezulwini, ukuba aa Incopho axis komhlaba nayo litshintsha indawo yayo, yaye oku kubangwa intshukumo amanqaku ekudibaneni kwe-ikhweyitha kunye baza. Ngenxa yoko, nokutsala zeNyanga ukubana sentshinyela of kwiinginginya Umhlaba ithande ukuba kuguqula umhlaba ukuze moya alo inqumla inyanga. Kodwa kulo mzekelo, la mabutho musani ukwenza phezu iqokobhe amanzi Umhlaba, kunye inginginya, kusekwe kwexeshana sentshinyela ngokwemilo yayo ellipsoidal.

Bonisa ibhola abhaliwe ellipsoid esemhlabeni apho inxulumene kwi pole. Le ibhola itsalelwa Inyanga kunye nemikhosi Sun ngqo embindini. Ngenxa yesi sizathu, i-axis koMhlaba kuhlala ingatshintshanga. Le umtsalane omele kwexeshana sentshinyela idla ukuzitshintsha Umhlaba ngendlela yokuba womgca ikhweyitha Umhlaba kunye nenjongosenzi ngaxeshanye enomtsalane, ukudala le ngongoma wumbe. Ilanga kulo nyaka kabini asuka kwi-ikhweyitha ukuba ± 23,5 °, kunye nokususwa kwe-ikhweyitha kwenyanga ngenyanga phantse ± 28,5 °.

zokudlala abantwana phezulu uvula imfihlelo encinane

Ukuba Umhlaba akazange phendula, bekuya badla ukugoba, ngokungathi bevuma, kangangokuba lonke ikhweyitha ixesha ubukele ilanga nenyanga. Nangona kunjalo, ngenxa ubunzima enkulu kunye inertia yoMhlaba, ukwehla ezinjalo bekuya kuba lincinane kakhulu, ukususela kwi utshintsho ekhawulezayo loo kolwalathiso Umhlaba akazange abe nexesha sicaphuka. Siyiqhelile le nto kulo mzekelo phezulu kukujikeleza lomntwana. Gravity ijonge sibhukuqe le gyroscope, kodwa amandla centripetal kuthintela ukuba ekungqulekeni. Ngenxa yoko, ukuba uhamba axis, uchaze imilo etsobhileyo. Kwaye ngokukhawuleza intshukumo, imilo elimxinwa ngakumbi. Ngokufanayo, iziphatha kunye axis komhlaba. Olu luhlobo nokuqinisekisa uzinzo yayo esithubeni.

I-engile ukutyekela axis komhlaba luchaphazela imozulu

Umhlaba ityhalela emhlabeni kweLanga nokujikeleza into efana kakhulu ukuya kwisangqa. Ukuqwalasela isantya iinkwenkwezi ekufuphi baza, ke ukuba nanini na sifumana kufutshane iinkwenkwezi omnye ukusuka wabachasa esibhakabhakeni ngesantya kweekhilomitha 29.5 ngeyure nganye. Utshintsho onyaka na isiphumo. Kukho kukodwa axis utyekelo ukuya moya komzila kunye nama-degrees 66.5.

Ngenxa komzila encinane okweqanda ngayo emhlabeni ngo January, kufutshane kancinci ukuya Sun ngaphezu ngoJulayi, kodwa umahluko ayikho kude kangako. Ngoko ke, impembelelo kwi yokwamkela sobushushu inkwenkwezi yethu avulekile.
Izazinzulu zikholelwa ukuba axis komhlaba - isicwangciso ekucaphukisayo iplanethi yethu. Uphononongo lubonise ukuba axis ukuthambeka engile isalamane komhlaba ukuya moya ka orbit kwixesha elidlulileyo kwakukho ezahlukeneyo watshintsha ngamathuba athile. Ngokutsho legend sele beza kuthi malunga ekutshatyalalisweni Phaeton lencazelo zikaPlato ngayo reference esikhoyo esqwini ukufuduka kweli xesha yoyikekayo kwi ° 28. Le ntlekele kwenzeka ukuba ube neminyaka engaphezu kweshumi lamawaka eyadlulayo.

bit Pofantaziruem kwaye utshintshe i engile utyekelo bomhlaba

Ekhoyo namhlanje, i-engile axis isalamane komhlaba ukuya moya le okuwo 66.5 ° kwaye inikezela ngaphantsi kakhulu ubushushu ukuhla yasebusika - ehlotyeni. Umzekelo, ukuba le engela ibe malunga nama-45 °, eya kwenzeka inkululeko of eMoscow (55,5 °)? NgoMeyi ilanga phantsi kwezi meko zifikelele bade (90 °) kwaye abangenamakhaya ukuba °-100 (55,5 ° + 45 ° = 100.5 °).

Nala spring ilanga kwezithuthi enzima iza kudlula ngokukhawuleza kwaye ukufikelela incopho lobushushu ngoMeyi, kwi-ikhweyitha, kunye injikalanga ubuninzi. Emva koko, ukuba buthathaka kancinane, njengoko ilanga udlula bade, bekuya kusinda kancinane. Babuyela emva, abapasa bade kwakhona. Kwiinyanga ezimbini, ngoJulayi nangoMeyi, babeza waphawula ubushushu zingenakunyamezeleka, malunga 45-50 degrees Celsius.

Ngoku cinga uya kuthelekelela into ebinokwenzeka kwelokuba ndobudlulisa ubusika, umzekelo, eMoscow? Emva abapasa i bade yesibini isikhanyiso yethu uziphaluse kwinyanga ka December ukuya degrees 10 (55,5 ° -45 ° = 10,5 °) ngaphezu kolundi. Oko kukuthi, kunye nendlela kuDisemba, ilanga ndandibethwa ixesha elifutshane ngoku, ngokuvuka ephantsi ngaphezu kolundi. Ngeli xesha, ilanga kukhanya iiyure 1-2 ngosuku. Phantsi kweemeko ezinjalo, ubushushu ubusuku ngaphantsi -50 degrees Celsius.

version ngalinye nasekusungulweni ilungelo lokuphila

Njengoko ubona, kuba imozulu planethi kubalulekile, ikona apho axis komhlaba. Le yinkolelo esisiseko kwi ngobulali neemeko kwemozulu zokuphila. Nangona mhlawumbi phantsi kweemeko ezahlukileyo emhlabeni, zazivelela kwakuya kufuna umntu ngendlela elifuna eyahlukileyo, ukudala iindidi ezintsha zezilwanyana. Kodwa ke ubomi waqhubeka ukuba zikhona kwezinye iyantlukwano wayo, kwaye kungenzeka ukuba wafumana indawo umntu "ezahlukeneyo" kuwo.
