IPlanethi yoMhlaba isaqhubeka inika izinto ezothusayo kuluntu lwezenzululwazi., eqwalasela ngenyameko zombini ukuziphatha kwayo kwangaphakathi kunye nemiqondiso evela kumphezulu. Inkqubela phambili yamva nje igxininise iinkqubo zejoloji kunye neenguqu ezijikelezayo ezichaphazela ukwakheka kweplanethi nobomi bemihla ngemihla, ukususela kwimvelaphi yeelwandlekazi ezintsha ukuya kumlinganiselo ochanekileyo wexesha.
Kwiiveki zamva nje, ingqalelo iye yagxila kwizinto ezimbini: ukufunyanwa kwee-mantle pulses ezinesingqi esingaphantsi kweAfrika., ekwaziyo ukuqhekeza ilizwekazi kwixesha elizayo elikude, kwaye ukukhawuleza okungalindelekanga kokujikeleza koMhlaba eye yafinyezwa ngeentsuku ezimbalwa, into edida abaphandi kwaye iphikisana nembali.
Ubungqina obutsha malunga nokuvela koqweqwe loMhlaba e-Afrika
Iqela lamazwe ngamazwe elikhokelwa yiYunivesithi yaseSouthampton liye labhala ubukho be-pulses yamatye atyhidiweyo. phantsi kommandla waseAfar kumntla-mpuma weAfrika. Lo mcimbi, uchazwa njenge amaza engubo eshushu aphakamayo ngesingqi, inxulumene ngokuthe ngqo ne-progressive fracturing yelizwekazi, kwindawo apho iziphene ezintathu zetectonic zidibana khona. Ekuhambeni kwexesha, le nkqubo inokukhokelela ekwahlulweni kwemihlaba nasekudalweni kolwandle olutsha, imeko enika ithuba elikhethekileyo lokujonga indlela amazwekazi atshintsha ngayo kwizigidi zeminyaka.
Uphando, olupapashwe kwijenali yezenzululwazi iNature Geoscience, luyibonisile loo nto Ezi pulse azihambi ngokulinganayo, kodwa kunokuba ngamaxesha aphawulwe ngesakhiwo samacwecwe aphezulu. Uhlalutyo lwemo yendalo engaphezulu kwekhulu leesampuli zentaba-mlilo luye lwasivumela ukuba siphinde sakhe I-dynamics phakathi komsebenzi wangaphakathi woMhlaba kunye neenkqubo ezibonakalayo kumphezuluImikhondo yeekhemikhali efunyenweyo ibonisa ukuba Umsebenzi onzulu we-mantle unxulunyaniswa ngokusondeleyo nokunyakaza kwepleyiti, enempembelelo ebalulekileyo ekuveleni kweentaba-mlilo neenyikima.
Le fracturing yelizwekazi ibonakala kwi-Afar Yenye yeemeko ezimbalwa apho abaphandi banokungqina ukuzalwa kolwandle ngexesha lokwenyani (ukuthetha ngokwejoloji), ukubonisa ukuba Umphezulu woMhlaba awumi, kodwa umphumo weenkqubo zangaphakathi ezisebenzayo nezinzima..
Ukujikeleza koMhlaba phantsi koqwalaselo ngenxa yokukhawulezisa kwawo okungalindelekanga
Ngaxeshanye njengoko kuphandwa umhlaba ongaphantsi komhlaba, Ukujikeleza koMhlaba kuye kwaba ngundaba-mlonyeni ngokubonisa izinto ezingaqhelekanga. Ii-arhente ezinoxanduva lokulinganisa ixesha, ezifana ne-International Earth Rotation and Reference Systems Service, zichongiwe. ezinye zeentsuku ezimfutshane kwezakha zarekhodwa enkosi kusetyenziso lweewotshi zeathom ezichane kakhulu. NgoJulayi nango-Agasti walo nyaka, iintsuku zilindeleke ukuba zibe mfutshane kancinci kunesiqhelo iiyure ezingama-24, ukuya kuthi ga kwi-1,5 millisecond ezilahlekileyo ngosuku olunye.
Olu tshintsho kujikelezo luyangqubana nomkhwa oye wabonwa kangangeenkulungwane., apho utsalo lomxhuzulane lweNyanga lwacothisa ukujikeleza koMhlaba. Iingcali azikafumani isizathu esiqinisekileyo soku kunyuka kwesantya, nangona ezinye iingqikelelo zikhomba kwiinkqubo zangaphakathi ezingaqondwa kakuhle okanye ukusasazwa ngokutsha kwenkitha yabantu emva kweenyikima ezinkulu. Uluntu lwezenzululwazi luhlala lumangalisiwe ngesantya solu tshintsho kunye nendlela oluchaphazela ngayo umlinganiselo wexesha lehlabathi jikelele, eliye lafuna ukuza kuthi ga ngoku ukuqaliswa kwemizuzwana yokuxhuma ukuhlawulela ukucotha kwendalo.
Imilo engqukuva yeplanethi kunye nomngeni we-flat-earthism
Phakathi kwezi ngxoxo kunye nobungqina obutsha, Iithiyori zeyelenqe eziphika ubume obungqukuva boMhlaba zisajikeleza. Nangona kunjalo, Inzululwazi ibonise ukugoba koMhlaba ngendlela elula nephindaphindiweyo.Ukusuka kuqwalaselo lwakudala lweenqanawa ezithi zinyamalale kancinci kancinci elundini ukuya kwimifuniselo efikelelekayo kuye nabani na, ingqiqo kunye nokuqwalaselwa ngokuthe ngqo kuko konke okufunekayo ukuze kuqinisekiswe ubunzulu beplanethi. Ababhali-mbali kunye neengcaphephe bagxininisa ukuba, nakwiXesha Eliphakathi, ulwazi lokumila koMhlaba olungqukuva lwaluxhaphakile phakathi kwabaphengululi, luphikisa inkolelo yobuxoki yokuba umbono osicaba wawubanjwe kude kube kumaxesha akutshanje.
Kucacile ukuba Izinto ezintsha ezifunyenweyo kwindlela yokuziphatha yangaphakathi kweplanethi kunye nomlinganiselo ochanekileyo weentshukumo zayo Abagcini nje ukutyebisa ulwazi lwezenzululwazi, kodwa bancedisa ukugxeka ezinye zeentsomi eziqhubekayo kunye neengcamango eziphosakeleyo malunga noMhlaba kunye nokuvela kwawo.
Izinto ezifunyenweyo malunga Intsebenziswano phakathi kwengubo kunye noqweqwe eAfrika, ukuguquguquka kokujikeleza koMhlaba kunye novavanyo lokuqinisekisa ubume beplanethi obungqukuva. Babonisa ukuba uMhlaba yinto ephilayo eguqukayo kwi-metamorphosis engaguqukiyo, intsonkothe ngakumbi kwaye inomdla kunokuba isenokubonakala ekuqaleni.
