Kusukela kwabunjwa iplanethi yethu, bekulokhu kukhona a ukukhangwa kwenyanga emhlabeni Futhi njengoba sishilo ezihlokweni ezedlule, lelodwala elikhulu eliyindilinga elisibheka lisendaweni yonke lilawula amagagasi aseMhlabeni ngamandla alo amakhulu adonsela phansi.
Ngalo mqondo, njengoba imithetho yesayensi yemvelo ikhomba, lapho izinto ezimbili zisondelana, kulapho amandla ezidonsana ngawo amakhulu futhi yilokho okwenzeka phakathi kweplanethi yethu neplanethi yayo. luna. Ngokufanayo, ukukhanga kwenyanga emhlabeni kwenzeka ngokuyisisekelo lapho isathelayithi idonsela ulwandle ngakuyo futhi ibangele ukuthi iplanethi yethu iqhume kancane: lesi siqhumane sakha amagagasi.
Nokho-ke amagagasi esinawo ngenxa yokuthi iNyanga ilapho ekhona. Ukube ubuseduze kancane, amandla abeyoba namandla kakhulu, okungukuthi, amagagasi aphansi abezoba phansi futhi aphakeme abezokwenza amadolobha amakhulu anyamalale. ngasogwini. Ngakho-ke, ubudlelwano phakathi kwe- Ukuheha i-Moon-Terra Kubalulekile ukuqonda ama-tidal dynamics.
Isimiso sempilo
Umlando wethu usitshela ukuthi cishe eminyakeni eyizigidi eziyizinkulungwane ezingu-4.500 edlule, iplanethi elingana ne-Mars yashayisana nabancane. Umhlaba, futhi isikhubekiso saphonsa inani elikhulu letshe eliwuketshezi eduze kakhulu. Lokho kuhlangana kwaveza iNyanga futhi kwashintsha i-chemistry yokuqala yeplanethi yethu; ngamanye amazwi, yakha umhluzi wokuphila okukhulunywe ngawo ngenhla, nawo owawuqukethe i-hydrogen, i-nitrogen, nekhabhoni. Lokhu ukushintsha kwamakhemikhali kubalulekile ekuqondeni ukuphila eMhlabeni.
Nokho, lokho akugcinanga lapho, ngemva kweminye iminyaka eyizigidi ezingu-700 ngemva kwaleyo nhlamvu, iplanethi yethu yaphola, kwadalwa indawo. enamatshe, umhwamuko wamanzi wanqwabelana olwandle, futhi iNyanga yashukumisa lezo zilwandle. Njengoba kwasungulwa usokhemisi uJohn Sutherland, empeleni kwakuyilokhu kuqubuka kwamagagasi angaphambi komlando okwaqala ukuphila.
Ukukhanga kwenyanga emhlabeni kanye nomjikelezo wokuphila
Amadoda asendulo ayekhulekela iNyanga futhi amasiko amaningi asungula izinganekwane ezizungezile, njengaleyo yempisi esabekayo. Abanye bakholelwa ukuthi inyanga egcwele iyasicasula, ngisho nokuthi ngalobo busuku kuba nokudlwengula okwengeziwe, kulokho okuye kwabizwa ngokuthi i-Transilvania sequel. Nokho, lokhu kuyinto isayensi engazange ikwazi ukukufakazela. Nokho, okuqinisekileyo ukuthi izilwane ezihlukahlukene ziba namandla, zibubule futhi zivundile lapho kukhanya ilanga. Inyanga egcwele. Lesi simo singase sihlobane nokuziphatha kwezinhlobo ezithile phakathi nomjikelezo wenyanga.
Kulokhu, i- amakhorali izindawo ezishisayo, okuyisibonelo esicacile somjikelezo wokuphila, hlanganisa umjikelezo wabo wokuzala kanye nokukhululwa kwenyanga egcwele ebusuku ngesikhathi esisodwa. Ngokufanayo, cishe izinsuku ezingu-29, nenyanga egcwele, amakhorali akha ingubo entsha yamathambo ngaphezu kweyangaphambili futhi lokhu kuthuthukiswa kunqunywa umjikelezo ovamile weNyanga.
Isigqi kanye nokuhlala njalo kwenyanga
Inyanga ijikeleza njalo ezinsukwini ezingama-29, isikhathi esifanayo esithathayo ukuzungeza uMhlaba yingakho ihlale isikhombisa ubuso obufanayo. Eyethu iplanethiNokho, yenza njalo njalo ngamahora angu-24, kodwa kunesikhathi lapho uMhlaba wawuhamba ngokushesha kangangokuthi usuku lwaluthatha amahora angu-5. Ngakolunye uhlangothi, kusukela ekudalweni kwayo kanye neminyaka eminingi, amandla adonsela phansi eNyanga aphinde enza ukujikeleza koMhlaba. Futhi ngokulinganayo, isigqi esifanayo soMhlaba siphawulwe yisathelayithi yawo, ebuye ibonakale ezinhlotsheni ezahlukene zokuphila.
Ngakolunye uhlangothi, ososayensi bathi uma uMhlaba wehlile, ngenxa yalokho, i- Luna Usejahe lokho kusho ukuthi useyaqhela. Ngokuqondile, i-3,78 cm ngonyaka, ngokusho kwezibalo ezinembile zabacwaningi. Leli banga elikhulayo liphakamisa imibuzo ethokozisayo mayelana nekusasa lobudlelwano bethu neNyanga.
Ngakolunye uhlangothi, kusukela ukukhangwa kwenyanga emhlabeni kanye nokushayisana okwasungula i satellite, i-axis yoMhlaba iye yaba yi-oblique, izulazula engeli eliqinile lama-degree angu-23, okuvumela ukwahlukanisa kokukhanya kwelanga nezinkathi zonyaka, ukuhlala unomphela kwesimo sezulu, futhi ngenxa yalokho, umjikelezo wokuphila. Ngakho-ke, ukuxhumana phakathi kwe-eksisi yoMhlaba neNyanga kubalulekile ekuzinzeni kwesimo sezulu.
Iziphetho mayelana nokukhangwa kwenyanga emhlabeni kanye nomphumela wayo
INyanga izungeza uMhlaba ngebanga elilinganiselwa ku-384.400 km. Isakhiwo sayo singamakhilomitha angu-3.475, cishe ingxenye yesine yaleyo planethi yethu, enendawo engaba yizigidi ezingu-38 km2, futhi ubukhulu bayo buyi-1/81; lokhu kuyajabulisa ukuthi amandla adonsela phansi endaweni yangakini ingxenye yesithupha yomhlaba. Umphumela oqondile kakhulu walobu bunzima obuphansi ukuwohloka kwe umkhathi, okuholela emibuzweni eminingi ngezimo ezingase zibe khona ukube iNyanga ibingekho.
Isizathu sokwakheka kwamagagasi
Njengoba iNyanga izungeza Umhlaba wayo amandla adonsela phansi iheha izwekazi kanye nolwandle. Ndawonye amandla adonsela phansi oMhlaba ahlola iNyanga futhi ayivimbe ekuphumeni emzileni wayo.
Ngokufanayo, uthe ukukhangwa Moon unyakazisa izintaba futhi kwandisa igagasi elincane kodwa ebonakalayo oqweqweni lomhlaba. Ngesikhathi esifanayo, kuyathakazelisa izimbila nezilwandle, okukhuphula izinga lamanzi ngamamitha amaningana kwezinye izindawo. Lo mphumela ufana nalowo womshini odlula phezu kwetafula bese kwakheka isigaxa.
Amandla asetshenziswa iNyanga adala ukwakheka kwamagagasi okuthuthukisa izinga lolwandle. Njengoba izungeza uMhlaba kanye nezifunda ezintsha zingena ngaphansi kokubusa kwenyanga, amanzi agcwele anyakaza kakhulu, enze amagagasi aphezulu endaweni eyodwa namaza aphansi kwenye. I igagasi eliphansi ukhonjiswa engxenyeni yesine yesiyingi somhlaba ngaphambi kokudlula kweNyanga kanye nebanga elifanayo ngemuva, inqobo nje uma kukhona izilwandle nezilwandle.
Ekugcineni, ukukhanga kwenyanga emhlabeni ngisho nangaphandle kwethonya lesathelayithi yayo yenyanga, ulwandle nolwandle lwethu bekungaba namagagasi, nokho abemancane kakhulu. I-gravitational affinity yeLanga nayo iyangenelela Umhlaba. Lawa mandla anamandla kakhulu esimisweni sawo kanye nalelo elenziwa yiNyanga.
