Ungathini ukuba umhlaba uyekile ukujikeleza

Asiyiqondi, kodwa uMhlaba uyaqhubeka nokujikeleza. Ijikeleza ilanga. Yinto ebesiyifunda oko sisengabantwana. Noko ke, abantu abaninzi bayazibuza kuya kwenzeka ntoni ukuba umhlaba uyeka ukujikeleza.

Ngesi sizathu, siza kunikezela eli nqaku ukukuxelela ukuba kuya kwenzeka ntoni ukuba uMhlaba uyekile ukujikeleza, zeziphi iziphumo obuya kuba nazo kunye nokunye okuninzi.

Iimpawu zomhlaba

Umhlaba yiplanethi kwisixokelelwano selanga, kwakhiwa malunga ne-4550 yezigidigidi kwiminyaka eyadlulayo. Yesihlanu kwezona planethi zisibhozo kwiplanethi yelanga kwaye inkulu kwezine zomhlaba okanye ezinamatye. Njengamanye amaplanethi, ichaphazeleka ngeendlela ezahlukeneyo, nangona ezona ziphambili zichazwa ngokubhekisele kwilanga, ezizi: ukujikeleza, ukuguqulelwa, ukugqithiswa, ukunyuswa, i-Chandler wobble, kunye ne-perihelion precession. Ezona zidumileyo kukuguqulela nokujikeleza.

Eyokuqala kwezi kukuhamba kwesijikelezi-langa ukujikeleza ilanga, ngoxa ukujikeleza ikukujikeleza kwesibhakabhaka sijikeleza iasi yayo, yaye ukujikeleza kwesijikelezi-langa sethu kuye kwacotha kancinane kangangeebhiliyoni zeminyaka. Le nkqubo iyaqhubeka nanamhla, kwaye Kuqikelelwa ukuba ubude bosuku buyanda ngoku malunga ne-1,8 milliseconds ngenkulungwane. Bejongene nale nyaniso yenzululwazi, abantu bahlala bezibuza ukuba kuya kwenzeka ntoni kwisijikelezi-langa sethu ukuba ngenye imini uMhlaba uyeka ukujikeleza kwaye uyeka ukujikeleza.

Ungathini ukuba umhlaba uyekile ukujikeleza

Impendulo yengcali icacile, zonke izinto kunye nabantu abasemhlabeni baya kudutyulwa ngeli xesha umhlaba uyeka. Oku kungenxa Isantya sokujikeleza koMhlaba yi-1.770 yeekhilomitha ngeyure (km/h) kwi-ikhweyitha kunye ne-0 km/h kwiipali.. Nangona sasihamba ngesantya esimangalisayo, asizange siqonde ukuba siyashukuma. Emva koko, ukuyeka ngokukhawuleza ukujikeleza koMhlaba kuya kuvakala phezu komhlaba, ngendlela yokuba yonke into kwaye wonke umntu "abethwe" ngamandla e-centrifugal kunye ne-inertia yentshukumo, kubandakanywa nomoya, oya kudala izivunguvungu. - amandla omoya emhlabeni wonke.

Konke oku kuya kuncitshiswa kufutshane neepali, apho isantya sisezantsi kwaye ikuphela kweendawo ezinokusinda kule ntlekele. Kanye njengabantu ababekhwele inqwelomoya ngelo xesha.

umhlaba omtsha

Ngaphandle kwamandla e-centrifugal yentshukumo ejikelezayo, umxhuzulane uya kuhlala unjalo, udala ulwabiwo ngokutsha lomxhuzulane onokuthi uphazamise ibhalansi yolwandle. Iilwandlekazi ezimbini ezinkulu ziya kumila zijikeleze izibonda, zahlulwe lilizwekazi. Lo mmandla uphela wawuya kukhukuliswa ngamanzi, yaye eYurophu kuphela iSpeyin, iGrisi nakumazantsi eItali yayiza kuphuma emanzini.

Esinye isizathu solu kuphazamiseka lutshintsho oluphazamisayo kubude bemini nobusuku, njengoko ukunyakaza okujikelezayo kuyisizathu sokuba kwenzeke. Umhlaba uthatha iiyure ezingama-24 ukugqiba inguqu enye epheleleyo.. Ngoko ukuba uMhlaba uyekile ukujikeleza, usuku ngoku lunobude beentsuku ezingama-365, okanye unyaka (iinyanga ezi-6 zosuku, iinyanga ezi-6 zobusuku). Eli xesha liya kunikwa yintshukumo yoguqulo, iintsuku ezingama-365 ezithathwa yiplanethi ukwenza ujikelezo olupheleleyo lokujikeleza ilanga, okwenzeka ngexesha elinye nokujikeleza kwalo. Noko ke, ukuba uMhlaba ubunokuyeka ukujikeleza, bekuya kuthabatha iiyure ezingama-8.760 (okulingana nonyaka) ukubuyela kwindawo enye yokuqala emva kokugqiba ukujikeleza ilanga.

Okokugqibela, xa iziphumo eziphambili zifunyenwe, kufuneka sikhumbule ukuba amathuba okuba umhlaba ume ngxi nangawuphi na umzuzu anqabile, ngoko ke sinokuhlala phantsi siphumle.

Iimpembelelo kwizinto eziguquguqukayo zemozulu

Ukuba ibinokuyeka ukujika ngokupheleleyo, besiya kuba nesiqingatha sonyaka semini kunye nesiqingatha sonyaka ebusuku, oko kukuthi, imini nobusuku bekungayi kuphinda kusebenze ngokufanayo. Umhlaba uya kuhlala kwindawo efanayo phambi kwelanga isiqingatha sonyaka. Enye ihemisphere "yabhakwa" kwaye enye imnyama kwaye ibanda kakhulu. Emini, kwezi nyanga zintandathu, ubushushu bomphezulu buya kuxhomekeka kwisibanzi sethu, i-ikhweyitha ishushu kakhulu kunangoku kwaye iipali zityekele ekukhanyeni kwaye zingasebenzi kakuhle ekufudumezeni.

Ngokwethiyori, indawo ekukuphela kwayo enokuhlalwa kule planethi iya kuba yindawo encinci yangokuhlwa phakathi kweziqingatha ezibini. Ngaphandle kwako nakuphi na ukujikeleza, uMhlaba ubungayi kuba namaxesha onyaka. Loo ndawo yayiza kuba yinkangala. Ngelixa sisenoMhlaba oMntla wePole, apho imitha yelanga iya kuba kweyona engile yayo isezantsi, kunye ne-ikhweyitha, apho ukukhanya kubetha ngokuthe ngqo, akusekho intwasahlobo, ihlobo, ikwindla, okanye ubusika. Kukho iinyanga ezi-6 kuphela kunye neenyanga ezi-6 zobusuku.

Iipateni ze-atmospheri ezitshintshiweyo

Iipateni zeatmospheri eMhlabeni nazo zinxulumene nokujikeleza koMhlaba. Ukuba uMhlaba uyekile ukujikeleza, bekuya kuyitshintsha kakhulu indlela yokuhamba komoya. Oku kuya kuba sisiphelo senkanyamba. Umzekelo, naluphi na utshintsho ekuhambeni komoya lunokubangela ukuba iintlango zibonakale apho kukho amahlathi ngoku, okanye i-tundra enomkhenkce ukuze ihlale.

sala kakuhle kwi-auroras

Ukuba umhlaba uyekile ukujikeleza, umhlaba wayo wemagnethi awusayi kuphinda ukhule kwaye ubole kwixabiso lawo eliseleyo, ngoko i-Aurora Borealis yayiza kunyamalala kwaye iibhanti ze-radiation ze-Van Allen zinganyamalala, ukukhuselwa kwethu kwimitha ye-cosmic kunye nezinye iinqununu eziphezulu zamandla. Imagnethi yomhlaba iyasikhusela kwizinto ezinjengemitha ye-cosmic kunye nezaqhwithi zombane ezivela elangeni. Ngaphandle kwemagnethi, ubomi abunakuxhathisa imitha yeenkwenkwezi.

Ukuba yonke into ekwesi sijikelezi-langa iyeka ngokukhawuleza ukushukuma, oko kunokuthetha ukutshatyalaliswa kobomi ngoko nangoko njengoko sisazi. Ngaba sifanele sizixhalabise ngoku kunokwenzeka? Akunjalo. Sinokuphefumla lula. Amathuba okuba isiganeko esinjalo sibonakale singunothi kule minyaka imbalwa izayo yeebhiliyoni.

Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga nokuba kuya kwenzeka ntoni ukuba uMhlaba uyeka ukujikeleza.
