Phakathi kwenqwaba yolwazi mayelana nokushintsha kwesimo sezulu, ukufudumala kwembulunga yonke kanye nezibikezelo zesikhathi esizayo, imizwa yomphakathi isiqaphele kakhulu futhi inovalo mayelana nesiphetho seplanethi eminyakeni ezayo. Eqinisweni, izifunda eziningi emhlabeni wonke sezivele zinenkinga yokuphazamiseka kwesimo sezulu. Ukwenyuka kwezinga lokushisa eMhlabeni kuletha esinye isizathu sokukhathazeka. Ngenxa yalokhu kukhathazeka okukhona mayelana nesimo sezulu esikhuphukayo nezinga lokushisa loMhlaba, kungakholakala ukuthi abanye abantu bangase bafise ukuhlehliswa kwalo mkhuba kanye nomthelela wokupholisa esikhundleni salokho.
Nokho, ababaningi abantu abazi ukuthi izinga lokushisa langaphakathi loMhlaba lisithinta kanjani nokuthi izinga lokushisa beliyoba njani ukube umkhathi womhlaba ubungekho. Ngakho-ke, kulesi sihloko sizokutshela Iyiphi indima edlalwa izinga lokushisa langaphakathi lomhlaba nokuthi izinga lokushisa besingaba nalo ngaphandle komkhathi wethu.
Ukwakheka kanye nezinga lokushisa langaphakathi lomhlaba
Uma ungazi, umnyombo woMhlaba, ophakathi nendawo neplanethi, uyindawo efudumele kunawo wonke emhlabeni wethu. Ngakho-ke, uma sicabangela ukukhathazeka kwethu okuningi mayelana nokushintsha kwesimo sezulu nemithelela yako, yini engenzeka uma umongo uyeka ngokuzumayo ukukhiqiza ukushisa futhi uqale ukuphola?
Uphenyo lwe-Seismological lubonisa ukuthi itholakala maphakathi neplanethi kanye Ine-radius engaba ngu-3.500 km, emele u-60% wesisindo esiphelele soMhlaba. Lo mgogodla wakhiwe ikakhulukazi ingxubevange ye-nickel nensimbi, eyaziwa ngokuthi i-NiFe (lapho u-“Ni” esho i-nickel futhi “Fe” echaza insimbi). Ukwengeza, umgogodla ubonisa ukuminyana okukhulu, okuqukethe inani elibalulekile lezinto ezisindayo kanye nokuba khona okuncane kwezinsimbi ezilula nemikhondo ye-silicon. Amandla adonsela phansi emnyombweni cishe amakhulu ngokuphindwe kathathu kunalawo atholakala endaweni yeplanethi.
Kubalulekile ukuqaphela ukuthi, nakuba izinga lokushisa layo selilikhulu kakade, liphinde liqiniswe ukushisa okukhiqizwa ukungqubuzana kwamandla adonsela phansi okubangelwa ukunyakaza kwezinto eziminyene eduze komngcele phakathi komnyombo kanye nengubo.
Nakuba kungase kubonakale kuyisiphakamiso esithakazelisayo, ukwenzeka okunjalo ngeke kuthandeke. Umnyombo woMhlaba wenza imisebenzi eminingi edingekayo ukuze kugcinwe ukuphila emhlabeni wethu.. Ukupholisa umnyombo kungaphazamisa yonke le misebenzi ebalulekile, okuholela kuMhlaba ongenakuphila. Empeleni, lokhu kufingqa imiphumela emibi.
Ake sibone ukuthi yimiphi imiphumela ethile engavela ekwehleni kwezinga lokushisa enkabeni yoMhlaba.
Ukupholisa umnyombo woMhlaba
Ukupholisa komnyombo woMhlaba ngeke nje kubangele ukuntuleka kwamandla e-geothermal, kodwa futhi kuzoletha ubumnyama emhlabeni wonke. Lokhu kungenxa yokuthi izinkampani zamandla emhlabeni jikelele zisebenzisa ukushisa okuvela kuqweqwe loMhlaba ukushisisa amanzi, zidale isitimu esishayela izinjini zomoya ohlelweni oluyinkimbinkimbi lokukhiqiza ugesi. Ngakho-ke, umnyombo obandayo usho umhlaba omnyama.
Ngaphezu kwalokhu, iplanethi izobhekana nezinsongo eziphawulekayo ezivela emisebeni eyingozi ekhishwa yiLanga, njengoba umongo udlala indima ebalulekile ekudaleni izendlalelo ezivikelayo zomkhathi nozibuthe ezizungeze indawo yomhlaba. I-ayoni eguquguqukayo njalo ngaphakathi komgogodla ikhiqiza lesi sivikelo esesabekayo emhlabeni wonke, esivikela emisebeni eyingozi ye-cosmic nelanga.
Ngaphandle kwalesi sivikelo, bekungaba nokuqhuma okunamandla kwemisebe ekwazi ukudambisa umdlavuza futhi kushise ngokweqile iplanethi. Ngaphezu kwalokho, imimoya yelanga ilokhu ihlasela iplanethi yethu; nokho, lamandla angabonakali ngokuyinhloko ayawaphambukisa. "Ukuqhuma" okuthile komoya welanga kunamandla okomisa ulwandle nemifula yonke, kodwa umnyombo oshisayo weplanethi yethu udlala indima ebalulekile ekugwemeni imiphumela enjalo.
Imibuzo eminingi ecatshangelwayo igijima emiqondweni yabantu abaningi, ikakhulukazi mayelana namakhambi angenzeka okushisa komhlaba noma ukushintsha kwesimo sezulu. Lo mbono othize ungowaleyo ndawo. Nokho, kumelwe kubhekwe njengenkoleloze, njengoba ukugcwaliseka kwesenzakalo esinjalo emhlabeni wethu, njengoba kuboniswa yilokho okuphawulwe ngenhla, kungaphumela enhlekeleleni ephelele. Ekugcineni umhlaba wawuzoshintsha ube iMars entsha.
Izinga lokushisa lomhlaba lapho ungekho umkhathi
Izinga lokushisa elijwayelekile lamanje lomhlaba licishe libe ngu-13,9 degrees Celsius, isimo esisekela izinhlobonhlobo zezinto eziphilayo nendawo yazo ezungezile kanye nemisebenzi eyahlukahlukene yabantu.
Uma ungekho umkhathi woMhlaba, izinguquko ezinkulu ezimweni bezizokwenzeka. Okokuqala, izinga lokushisa elijwayelekile leplanethi lingase lehle lifinyelele cishe ku -12 noma -15 ºC, okungenza ingxenye enkulu yoMhlaba iwele ngaphansi kwezinga elingu-0ºC. Ngenxa yalokho, iqhwa lalizobusa phezu kwamanzi awuketshezi, nakuba ezinye izindawo zisazoba namanzi awuketshezi.
Ngaphezu kwalokho, uma ungekho umkhathi, uMhlaba ubungeke uswele isivikelo emisebeni ye-ultraviolet ekhishwa yiLanga, kanye nokushayisana kwama-meteorite amancane, okungenza ukuba khona kokuphila phezu kwawo kucishe kungenzeki.
Ukuntuleka komkhathi kungaphumela ekubeni umhlaba ungahlali muntu, obonakala ngamazinga okushisa aphakeme kanye nokungabikho kwamanzi awuketshezi.
Imiphumela yokuguquka kwesimo sezulu
Kuwo wonke umlando wawo, isimo sezulu soMhlaba siye sabhekana nezinguquko eziningi eziqhutshwa yizinto zemvelo, kuhlanganise ukuqhuma kwentaba-mlilo, izinguquko kumjikelezo weplanethi kanye noshintsho ekubunjweni komkhathi, phakathi kwezinye izici ezihlukahlukene.
Imiphumela eyinhloko yokushintsha kwesimo sezulu yilena elandelayo:
- Ukuguqulwa kokujikeleza kolwandle nokuhluka kumazinga emvula, okungenzeka kwenyuke noma kwehle kuye ngendawo ethile.
- Ukukhuphuka kwezinga lolwandle.
- Ukuhlehla kwezinguzunga zeqhwa.
- Ukwanda kokwenzeka kwezehlakalo zesimo sezulu esibi kakhulu.
- Ukuqina kokushisa namagagasi abandayo.
- Ukukhula kokufuduka okuphoqelelwe, okuqhutshwa kokubili izimo eziphuthumayo ezivela ezinhlekeleleni kanye nezizathu zokuqashwa.
Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi mayelana nokuthi izinga lokushisa langaphakathi loMhlaba lisithinta kanjani nokuthi iplanethi yethu ibingaba naliphi izinga lokushisa ngaphandle komkhathi.
