Yini lokhu? Kungani amaholide abanda futhi izimpi zibanda? Isivinini sokugeleza kweplanethi sihamba, ngakho-ke ngonyaka indawo ngayinye ibona uLwandle oLukhuni phezulu noma ngezansi emkhathini, kanye ngehora elingaphezulu noma elincinane. Lezi zingxenye zibonisa ukuthi kunoma yiliphi indawo nanoma yisiphi isikhathi.
Indlela yokusetshenziswa kwayo: Khetha idolobha lakho ngaphansi kwe "Indawo yakho" (noma cindezela i-latitude), bese ucindezela usuku noma inkinobho ye-solstice. Dlulisa i-3D Earth ukuze uyijikelezise.
Indawo yakho: London
Bona ukuthi ilanga lisebenza kanjani lapho uhlala khona, ngosuku okhethe phezulu.
Isiphequluli sakho sizobuza wena kuqala. Indawo yakho isetshenziswa kuphela kulekhasi, ukwenza izibalo. Ayikho egcinwe noma ithunyelwe nakweyiphi indawo.

- Ilanga liphezulu kakhulu ku
- I-engile ephezulu kakhulu yelanga
Uhlu lwezifunda: GeoNames (geonames.org), CC BY 4.0. Ukuvuka kwelanga, ukuvala kwelanga kanye nendawo yelanga: amafomula we NOAA Global Monitoring Laboratory solar calculator, kusuka ku J. Meeus, Astronomical Algorithms. Ukuvuka kwelanga nokuvala kwelanga kwenzeka lapho ingxenye ephezulu yelanga ithinta umgwaqo ovulekile, evumela indlela umoya ojikeleza ngayo ukukhanya, ngakho zinikeza usuku olude kakhulu kunesithombe se-geometric ngaphesheya. Amabanga osikhathi avela kwisiphequluli sakho.
Ubude bemini lapha buyi-geometric (iphakathi kwelanga ehlathini elivulekile). Umoya ugoba ukukhanya kwelanga, ngakho imini yangempela iyinhlamvu encane ende.
Zama lokhu
- Khetha isixeko sakho, bese ucindezela "i-June solstice" ne "December solstice".Isixhumanisi: Ingabe usuku lwakho olude lude kangakanani uma kuqhathaniswa nolunye oluncane? Uma uhlala eduze kwe-equator, ibanga lizoba elikhulu.
- Khetha i-Quito, enyakatho-ntshonalanga, bese ucindezela Dlala.Isixhumanisi: Imini ihlala eduze kwehora le-12 lonke unyaka wonke futhi ilanga lihlala liphezulu emini. Enyakatho yezwekazi, amasimu afana nemvula, hhayi ukukhanya kwelanga.
- Khetha iReykjavik bese ucindezela "i-June solstice".Isixhumanisi: Ilanga lihlala ngemuva kwemini futhi likhuphuka kabusha ngaphambi 3 a.m., futhi alikwazi ukumnyama ngokuphelele. Umfula we-Arctic Circle (66.6° N) awusetshenzisiwe ngokuphelele.
- Rola i-axis tilt ku-0°, bese u-90°.Isixhumanisi: Uma kungakhombi, usuku lonke luyihora eli-12 lide kuwo wonke amadolobha futhi amasimu aphela. Uma kunomsindo omkhulu, njenge-Uranus, ehlobene nengxenye yayo, amasimu aqala ukuba namandla kakhulu.
Ingabe indawo iphakathi kwe-equator noma enyakatho, kusuka ku-0° e-equator kuya ku-90° eNorth noma South Pole. ILondon iyilapho 51.5° N; Sydney iyilapho 33.9° S.
Ingabe ibanga elidlulayo le-axis yokujikeleza kweplanethi lilinganiswe nendlela yayo ejikelezayo ilanga: cishe 23.4°. I-tilt, hhayi ubude bethu belanga, yilokho okubangela amasimu.
Okuningi ku-glossary →I-latitude lapho ilanga lihamba khona ngokuqondile phezu kwekhanda emini ngosuku oluthile. Lisuka ku-23.4° N ngoJuni kuya ku-23.4° S ngoDisemba futhi emuva.
Okuningi ku-glossary →Izinsuku ezimbili ngonyaka, cishe ngoJuni 21 noDisemba 21, lapho ilanga lifinyelela khona enyakatho noma emlandweni. Ziletha amasonto ade kakhulu nemizuzu emincane.
Okuningi ku-glossary →Izinsuku ezimbili ngonyaka, cishe ngo-20 kuMashi no-22 kuSepthemba, lapho ilanga liphezulu eqhwani futhi usuku nemini zilingana khona kuwo wonke indawo.
Okuningi ku-glossary →Isikhathi lapho ilanga liphezulu kakhulu emkhathini ngosuku oluthile. Kwikhalenda akufanele kube 12:00, ngenxa yezindawo zesikhathi kanye nesikhathi sonyaka.
Kusenyakatho ilanga lingahlala liphezulu amahora angama-24 wonke ehlobo (ilanga eliphakathi kwemini) futhi lihlale ngezansi komgwaqo ohamba phambili yonke izinsuku ebusika (ilanga lesifunda).

Amathuluzi nama-lessons asebenzisa amamodeli alula ukufundela kuphela. Akufanele asetshenziswa ukuhlola, ukuhlela umsebenzi noma noma yiluphi ukhetho lokusebenzela. Izitifiketi zimahhala futhi aziqinisekisiwe. Funda isichazamazwi sezinto ezifundiswayo
