Indlela Ilanga Elithinta Ngayo Uhlelo Lwelanga
ILanga liyisikhungo sesimiso sethu selanga futhi lidlala indima ebalulekile ekuthonyeni konke endaweni yethu ebanzi. Njengenkanyezi enkulu kunazo zonke ohlelweni lwelanga kanye nento enobukhulu obukhulu, iLanga aligcini nje ngokunikeza ukukhanya namandla adingekayo empilweni eMhlabeni kodwa futhi lilawula ukuziphatha nokunyakaza kwezidalwa eziningi zasezulwini. Kulesi sihloko, sizohlola kabanzi izindlela ezahlukene iLanga elithonya ngazo uhlelo lwelanga.
1. Amandla Adonsela Phansi Elanga: Umqaphi Wesimiso Selanga
Amandla adonsela phansi eLanga yiwona anamandla amakhulu kakhulu ohlelweni lwelanga. Njengoba isisindo sifinyelela cishe ku-99,86% wobunzima besistimu yelanga, amandla alo adonsela phansi agcina amaplanethi emizuliswaneni yawo. Wonke umzimba wasezulwini ohlelweni lwelanga, kusukela kumaplanethi amakhulu kuya kuma-asteroid amancane, uhlala udonsa iLanga, uvimbela ukuba angaphambuki aye emkhathini noma ashayisane.
Ngaphandle kokudonsa kweLanga ngamandla adonsela phansi, amaplanethi anjengoMhlaba, iMars, neJupiter abengeke akwazi ukugcina imijikelezo ezinzile. Cishe abezophuma ohlelweni lwelanga noma ashayisane ngenxa yezindlela zawo ezingalawuleki. Ngakho-ke, amandla adonsela phansi eLanga ayisihluthulelo sokugcina isakhiwo kanye nokuqina kwesimiso selanga.
2. Ukukhanya kwelanga: Umthombo Wokuphila Namandla
Ukukhanya kwelanga kuwumthombo oyinhloko wamandla azo zonke izinto eziphilayo eMhlabeni. Inqubo ye-photosynthesis, esetshenziswa yizitshalo ukuguqula ukukhanya kwelanga kube amandla amakhemikhali, iyisisekelo sochungechunge lokudla. Ngaphandle kokukhanya kwelanga, izitshalo bezingeke zikwazi ukukhiqiza umoya-mpilo nokudla, okwenza ukuphila eMhlabeni kungenzeki.
Ngaphezu kwalokho, amandla avela eLangeni aqhuba umjikelezo wamanzi ngezinqubo zokuhwamuka kanye nokujiya, okuyisisekelo sokusimama kwemithombo yamanzi yeplanethi yethu. Ngokwamukela ukukhanya kwelanga, izilwandle, imifula, kanye neminye imithombo yamanzi kungabhekana nomjikelezo wemvula, obalulekile ekusindeni kwazo zonke izinto eziphilayo.
3. Umsebenzi Welanga: Umthelela Esimweni Sezulu Nasesimo Sezulu
ILanga lidlula emjikelezweni womsebenzi othinta isimo sezulu soMhlaba kanye nesimo sezulu. Ukugqashuka kwelanga, ukuqhuma kwe-coronal mass, kanye neziphepho ze-geomagnetic konke kuyizinto ezihlobene nomsebenzi welanga. Lolu hlobo lomsebenzi lungabangela ukuphazamiseka ensimini yamagnetic yoMhlaba, lukhiqize ama-aurora, futhi luphazamise ukuxhumana kwesathelayithi kanye nezinhlelo zokuzulazula.
Izinguquko emisebenzini yelanga zingathinta nesimo sezulu sesikhathi eside soMhlaba. Abanye ososayensi bacabanga ukuthi ukwehluka kwamandla elanga kungadlala indima ekushintsheni kwesimo sezulu njengeNkathi Yeqhwa noma izikhathi zokufudumala komhlaba. Kodwa-ke, ukuhlobana okuqondile kanye nezimbangela zalezi zimo kusalokhu kuyindaba yocwaningo olusebenzayo.
4. Umoya Welanga: Amathonya Emkhathini
Umoya welanga uwumfudlana oqhubekayo wezinhlayiya ezishajayo ezikhishwa yiLanga. Lezi zinhlayiya zingaba nemiphumela emikhulu endaweni yasemkhathini. Amaplanethi anamasimu anamandla kazibuthe, njengoMhlaba, anezinhlayiya zemagnethi ezivikela emiphumeleni eminingi yomoya. Kodwa-ke, umoya welanga ungasheshisa izinhlayiya ezihamba ngokushesha ziye emkhathini woMhlaba, okubangela ama-aurora.
Umoya welanga ungalimaza nomoya wamaplanethi angenazo i-magnetospheres, njenge-Mars. Kunobufakazi bokuthi umoya welanga ubhubhise ingxenye enkulu yomkhathi omncane we-Mars, okufaka isandla ekulahlekelweni kwanoma yimaphi amanzi okungenzeka ukuthi ake aba khona lapho.
5. Imithetho kaKepler: Ukuqonda Ukuzungeza Kweplanethi
Ukuqonda kwethu ukuthi amaplanethi ahamba kanjani eLangeni kulandela imithetho kaKepler. Umthetho wokuqala kaKepler uthi umjikelezo weplanethi ngayinye uyi-ellipse eneLanga ligxile kokunye. Umthetho wakhe wesibili uthi umugqa ohlanganisa iplanethi neLanga ususa izindawo ezilinganayo ngezikhathi ezilinganayo, ugcizelela ukuthi iplanethi ihamba ngokushesha uma iseduze neLanga futhi ihamba kancane uma ikude. Umthetho wesithathu kaKepler ubikezela ukuthi isikwele sesikhathi sokuzungeza kweplanethi silingana ne-cube yebanga eliphakathi leplanethi neLanga.
Le mithetho ibalulekile ekuqondeni ukuguquguquka kwesimiso sonozungezilanga futhi isiza izazi zezinkanyezi ukubikezela izikhundla zamaplanethi ngokunemba okuphezulu, okubalulekile emisebenzini yasemkhathini kanye nocwaningo lwesayensi.
6. Ukwakheka Kwesistimu Yelanga: Yazalwa Ku-Nebula Yelanga
Okwesihlanu, iLanga lidlala indima ebalulekile ekwakhiweni kwesimiso selanga. Inkolelo-mbono eyamukelwa kabanzi ukuthi isimiso sethu selanga sakhiwe ngeqoqo legesi nothuli olubizwa ngokuthi i-solar nebula cishe eminyakeni eyizigidigidi ezingu-4,6 edlule. Amandla adonsela phansi eLanga abangela ukufinyela kwalesi simiso selanga, okwagcina kuholele ekwakhekeni kwamaplanethi nezinye izinto ohlelweni lwelanga.
Njengoba i-nebula yayincipha, amandla adonsela phansi aguqulwa aba ukushisa, okwafudumeza ingaphakathi le-nebula futhi kwakha i-protosun. Idiski ye-protoplanetary yabe isikhiwa izungeze i-protosun, lapho igesi nezinhlayiya zothuli zahlangana khona futhi zahlangana ukuze zakhe amaplanethi nezinye izinto esizaziyo namuhla.
7. Ikusasa Lesimiso Selanga: Ukuvela Kwelanga
Ekugcineni, ikusasa lesimiso sethu selanga lincike ekuguqukeni kweLanga. Njengamanje, iLanga lisesigabeni esibizwa ngokuthi ukulandelana okuyinhloko, lapho liguqula khona i-hydrogen ibe yi-helium ngokusebenzisa i-nuclear fusion. Kodwa-ke, eminyakeni eyizigidigidi ezimbalwa ezayo, iLanga lizophelelwa yi-hydrogen enkabeni yalo bese liqala ukushisa i-helium, okuzolibangela ukuba lande libe yi-red giant.
Kule nqubo, iLanga lizogubuzela amaplanethi angaphakathi, okuhlanganisa noMhlaba okungenzeka kakhulu. Ekugcineni, iLanga lizolahlekelwa yizingqimba zalo zangaphandle, lishiye ingaphakathi elaziwa ngokuthi i-white dwarf. Kuleli qophelo, isimiso sethu selanga sizohluka kakhulu kulokho esikwaziyo namuhla.
Ekuphetheni, ithonya leLanga ohlelweni lwelanga lijulile futhi liphelele. Kusukela ekudonseleni kwalo amandla adonsela phansi, okulawula imijikelezo yamaplanethi, kuya emisebeni yalo, enikeza amandla abalulekile, kusukela emsebenzini walo othonya isimo sezulu soMhlaba kuya ekuguqukeni kwalo okuzonquma ikusasa lesimiso selanga, iLanga liyisikhungo esingenakufakwa esikhundleni sendawo yonke yethu. Ukuqonda indima kanye nomthelela weLanga kusisiza ukuba siqonde indawo yethu endaweni yonke futhi kuyingxenye yesayensi yezinkanyezi ehlala ishintshashintsha.
