Umkhangeli zincwadi wexesha
Ukunqunyulwa kwehlabathi, ubude belanga kunye nobude bosuku nakweyiphi na indawo nomhla.

Umkhangeli zincwadi wexesha
Yintoni le? Kutheni amaxesha obusika ashushu neentsuku zasehlotyeni zibanda? Umjikelo womjikelo wehlabathi ujikeleze, ngoko ke ngexesha lonyaka indawo nganye ibona ilanga liphezulu okanye liphantsi kwisibhakabhaka, kwaye ngeyure ezininzi okanye ezincinane. Eli sixhobo sibonisa ukuba nakweyiphi na indawo nangaliphi na ixesha.
Indlela yokusetyenziswa kwayo: Khetha isixeko sakho phantsi kwe "Indawo yakho" (okanye rhuqa ubude), emva koko rhuqa umhla okanye nqakraza iqhosha le-solstice. Rhuqa i-3D Earth ukujika.
Indawo yakho: London
Bona indlela ilanga eliziphatha ngayo apho uhlala khona, kumhla okhethiweyo ngasentla.
Umkhangeli zincwadi wakho uzakubuza kuqala. Indawo yakho isetyenziswa kuphela kule phepha, ukwenza izibalo. Ayiyi kugcinwa okanye kuthunyelwa naphi na.

Sunrise and sunset are when the top edge of the Sun touches a flat horizon, allowing for the way air bends light, so they give slightly longer days than the geometric figure above.

Ubude bemini apha buyi geometri (indawo esembindini welanga kwindlela ethe tyaba). Umoya ugoba ilanga, ngoko ke iintsuku ezinyanzelekileyo ziyintsuku ezimbalwa ezide.
Zama oku
- Khetha umzi wakho, emva koko nqakraza "i-June solstice" ne "i-December solstice".Isaziso: Imihla yakho ende ide kangakanani na xa kuthelekiswa nemini efutshane? Xa uhlala kude kakhulu kwi-equator, uninzi lwesithuba lukhulu.
- Khetha i-Quito, kwi-equator, kwaye ucinezele Dlala.Isaziso: Usuku luhlala likhulu kuneyure ezi-12 ngonyaka wonke kwaye ilanga liphezulu ngexesha lemini. Kufutshane ne-equator amaxesha emvula afana nomlilo, hayi ukukhanya kwelanga.
- Khetha iReykjavik kwaye ucinezele "i-June solstice".Isaziso: The Sun sets just after midnight and rises again before 3 a.m., and it never gets fully dark. North of the Arctic Circle (66.6° N) it does not set at all.
- Rhuqa umthambeko we axial ukuya kwi 0°, emva koko ufike kwi 90°.Isaziso: Ngaphandle kokungathathi hlangothi, yonke imini imalunga neeyure ezili-12 kude naphi na kwaye imijikelo iyaphela. Ngento ethe nkqo, njenge Uranus, ethe yathambekela ngasecaleni kwayo, imijikelo ivela ngokugqithisileyo.
Iphi na indawo ebekwe ngasentla okanye ezantsi kwe-equator, ukusuka kwi-0° kwi-equator ukuya kwi-90° kumntla okanye kumzantsi wePole. ILondon ikwi-51.5° N; iSydney ikwi-33.9° S.
How far Earth's spin axis leans compared with its path round the Sun: about 23.4°. The tilt, not our distance from the Sun, is what causes the seasons.
Okuninzi kwincwadi eneenkcukacha →The latitude where the Sun is straight overhead at noon on a given day. It swings from 23.4° N in June to 23.4° S in December and back.
Okuninzi kwincwadi eneenkcukacha →Imini ezimbini ngonyaka, malunga ne 21 kaJuni no 21 kaDisemba, xa ilanga lifika kumntla okanye kumzantsi ohamba phambili. Zizisa iintsuku ezide kunye nezifutshane.
Okuninzi kwincwadi eneenkcukacha →Iintsuku ezimbini ngonyaka, malunga ne-20 kaMarthi kunye ne-22 kaSepthemba, xa ilanga liphezulu kwi-equator kwaye ekuseni nobusuku zilingana naphi na.
Okuninzi kwincwadi eneenkcukacha →Ixesha elifutshane lelanga liphezulu kakhulu emthunzini kumhla onikiweyo. Kwikhusi ayikho 12: 00, ngenxa yendawo zexesha nexesha lonyaka.
Kufutshane neendawo eziphakamileyo ilanga lingahlala phezulu iiyure ezingama-24 zonke ebusika (ilanga eliphakathi kobusuku) kwaye lihlale phantsi kweendawo eziphakamileyo yonke imihla ebusika (ubusuku obuphezulu).
