EMkhathini, kunezigidigidi zezinkanyezi ngayinye ezungezwe namaplanethi amaningi amangalisayo, futhi thina bantu sihlale sikuthakasela ukuthola okuyinqaba phakathi kwawo. Kodwa iqiniso lokuthi uma noma yiziphi izidalwa ezithuthukile ezivela komunye umhlaba zingake zithole iplanethi yethu enguMhlaba, mhlawumbe zingathumela umlayezo ekhaya labo ukwazisa, “Sithole iplanethi eyingqayizivele kunawo wonke endaweni yonke, ezungezwe izinto eziphilayo ezihlukahlukene nezingaphili, eziqhosha ngomkhathi ongavamile.”
Ngakho-ke akungabazeki ukuthi iplanethi yethu eluhlaza okwesibhakabhaka igcwele izinto eziningi ezixakile nezingakholakali, futhi ezinye zazo zisadinga amagama ahloniphekile ukuze achazwe kahle. Namuhla, silapha ngamaqiniso ayi-12 axakile futhi angaqondakali kakhulu ngoMhlaba azokwenza ucabange:
1 | Umsuka wegama elithi “Earth”
Akukaze kukhulunywe ndawo emlandweni wethu ukuthi ngubani owaqamba iplanethi yethu ngokuthi “Umhlaba.” Ngakho-ke, akekho owaziyo ukuthi le planethi yathola kanjani leli gama. Nokho, ngokusho kwabanye, igama elithi “Umhlaba” livela egameni lesi-Anglo-Saxon elithi “Erda”, elisho “umhlabathi” noma “umhlabathi” futhi kucatshangwa ukuthi lineminyaka eyinkulungwane ubudala. Noma ngabe kwenzekani egameni layo kudala, sonke siyithanda kakhulu iplanethi yethu eluhlaza okwesibhakabhaka kanye negama layo lezintandane elithi “Umhlaba”. Akunjalo?
2 | Izigxobo zeplanethi ziyaphenduka!
Sonke siyazi ukuthi iNyakatho yindawo ethile ngenhla kwe-Alaska kanti iNingizimu ingezansi eduze naphakathi kwe-Antarctica. Kuyiqiniso impela ngokwesayensi yethu kepha kunenye imfihlakalo mayelana nezigxobo zaseNyakatho-Ningizimu okusamele ziphendulwe. Kule minyaka eyizigidi ezingama-20 ezedlule, izingongolo zikazibuthe ziye zaphaphalaza njalo eminyakeni eyizinkulungwane ezingamakhulu ambalwa. Yebo, uzwe kahle futhi ukuguqulwa kwesigxobo sokugcina kwenzeka eminyakeni engama-780,000 eyedlule, okusho ukuthi uma unekhampasi esandleni cishe eminyakeni engama-800,000 eyedlule, bekuzokutshela ukuthi inyakatho ibise-Antarctica. Yize ososayensi sebephethe ngokuthi ukuqhuma komhlaba, insimbi encibilikisiwe yomhlaba inika amandla lawa ma-polar acrobatics, akucaci ngokuphelele ukuthi yini ebangela ukuguqulwa kwangempela.
3 | Umhlaba uphethe ukhunta 'humongous'
Sonke siyazi ukuthi iplanethi yethu eluhlaza okwesibhakabhaka inezinto eziningi eziphilayo eziningi ezibandakanya izindlovu, imikhomo eluhlaza okwesibhakabhaka nezihlahla. Kepha abanye ongqondongqondo baze bazi ukuthi kukhona ama-coral reef undersea okuyizinto eziphilayo ezinkulu kakhulu eMhlabeni, ezinye zazo ezingabonakala ngisho emkhathini. Kodwa ngo-1992, kwazamazama wonke umuntu lapho kubizwa isikhunta esesabekayo I-Armillaria amakhowe atholakala e-Oregon, eMichigan, ahlanganisa okungenani amahektare angama-2,000 XNUMX futhi alinganiselwa ukuthi ayizinkulungwane zeminyaka ubudala.
4 | Ichibi elivele ngobusuku
Ichibi eliyimfihlakalo, elingaphezu kwamamitha ayi-10 ukujula, lavela ebusuku ogwadule lwaseTunisia. Abanye baphikelela ukuthi kuyisimangaliso, kanti abanye bakholelwa ukuthi kuyisiqalekiso. Kungakhathaliseki ukuthi kuyini, amanzi aluhlaza okwesibhakabhaka aluhlaza echibini anikeza le ndawo eyihlane ubuhle obuhle, okuyenza ibe ngenye yezindawo eziheha izivakashi ezweni.
5 | Amanye amafu ayaphila!
Kwesinye isikhathi, amafu amnyama agudluza ukwakheka avela eduze komhlaba abonakala kuyizinhlobo ezithile zezinto eziphilayo — futhi kungenxa yokuthi kunjalo. Lapho kungamakhulu, kwesinye isikhathi izinkulungwane ze- Izinkanyezi ndiza ngokushwibeka, amaphethini ahlanganiswe ngokuyinkimbinkimbi esibhakabhakeni, kubukeka njengamafu amnyama njengesigcawu sefilimu ethusayo. Lo mkhuba ubizwa ngokuthi ukububula. Ososayensi baphakamisa ukuthi izinyoni zihlanganyele kulo mbukiso omangalisayo lapho zifuna indawo yokulala noma ukugwema izilwane ezidla ezinye. Kodwa kuseyindida ukuthi, kanjani ngempela, bafinyelela ukuvumelanisa okuhle kangaka kwe-acrobatic endizeni.
6 | Umhlaba “unesikhungo Sendawo Yonke”
Kunendingilizi engaqondakali ebizwa ngokuthi “Isikhungo Sendawo Yonke” e-Tulsa, e-Oklahoma, e-United States eyakhiwe ngokhonkolo ophukile. Uma ukhuluma umile embuthanweni, uzozwa izwi lakho linanela kuwe kodwa ngaphandle kombuthano, akekho ongezwa lowo msindo we-echo. Ngisho nososayensi abakacaci kahle ukuthi kungani kwenzeka. Funda
7 | Umhlaba unomlando "wenhlekelele yefu lothuli" enemvelaphi engaziwa
Ngo-536 AD, kwakukhona ifu lothuli lomhlaba wonke elalivale ilanga unyaka wonke, okwaholela endlaleni nasezigulini ezisabalele. Ngaphezu kwe-80% yeScandinavia nezingxenye zaseChina zabulawa yindlala, i-30% yaseYurophu yafa ngezifo eziwumqedazwe, kwawa imibuso. Akekho owaziyo imbangela ngqo.
8 | Kukhona isiziba amanzi aso aya esihogweni!!
Ezintabeni zase-Oregon, kunechibi eliyimfihlakalo elenzeka njalo ebusika, bese liphuma entwasahlobo ngezimbobo ezimbili ezansi kwechibi, lenze idlelo elibanzi. Akekho onesiqiniseko sokuthi ayaphi wonke lawo manzi. Kodwa-ke, ososayensi bakholelwa ukuthi izimbobo ukuvuleka kwamashubhu odaka axhumene nochungechunge lwemigede yentaba-mlilo engaphansi komhlaba, futhi kungenzeka ukuthi amanzi agcwalisa i-aquifer engaphansi komhlaba.
Imfihlakalo efanayo: Izimpophoma zegedlela likaDeveli
Izimpophoma ze-Devil's Kettle eMinnesota zinohlangothi olulodwa oluthela phezu konqenqema futhi luqhubeke, nolunye uhlangothi olunomgodi ojulile ongashabalali ndawo. Abacwaningi bathele odayi, amabhola e-ping pong, nezingodo, kodwa akekho ongakwazi ukuthola ukuthi liyaphi.
9 | "I-Hum" Yomhlaba
Iminyaka engaphezu kwengu-40, ingxenye encane yabantu (cishe i-2%) emhlabeni wonke ikhononda ngokuzwa umsindo ongaqondakali obizwa kabanzi ngokuthi, “The Hum.” Umsuka walo msindo awukaziwa, futhi namanje isayensi ayikachazwa.
10 | "Indandatho yehlathi"
Yebo, uMhlaba uhlangene namahlathi kwezinye izindawo. Izindandatho zehlathi zingamaphethini amakhulu, ayindilinga okuminyana kwemithi ephansi emahlathini aseBoreal enyakatho yeCanada (futhi kubikwe eRussia nase-Australia). Lawa masongo angasukela ku-50m kuya cishe ku-2km ububanzi, namarimu angaba ngu-20m ukujiya. Imvelaphi yezindandatho zasehlathini akwaziwa, naphezu kwezinqubo ezimbalwa ezifana nesikhunta esikhula ngamandla, amapayipi e-kimberlite angcwatshwe, amaphakethe egesi avaleleke, ama-meteorite impact craters njll. eziphakanyiselwe ukudalwa kwawo.
11 | Umhlaba unesiqhingi esizidla “ngempophoma engaphansi kolwandle”
Ake ucabange ukuthi ubhukuda olwandle oluzolile bese kuthi kungazelelwe umuncelelwe empophomeni enkulu engaphansi kwamanzi! Yebo, lo mzuzu owesabekayo ungaba yinkazimulo yakho uma ubhukuda eduze kwesiqhingi esibizwa ngeRiphabhlikhi yaseMauritius esendaweni engamakhilomitha angama-2,000 XNUMX ukusuka ogwini oluseningizimu-mpumalanga ye-Afrika, eduze neMadagascar.
12 | Futhi iplanethi yethu eluhlaza okwesibhakabhaka ino "Steve!!"
Kunokukhanya okungaqondakali okuzungeza phezu kweCanada, i-Europe nezinye izingxenye ze-northern hemisphere; futhi lesi senzakalo esimangalisayo sasezulwini sibizwa ngokusemthethweni ngokuthi "Steve". Ososayensi abanaso isiqiniseko sokuthi yini ebangela uSteve, kodwa kutholwe abathanda i-Aurora Borealis abayimfundamakhwela abayiqambe ngesigcawu Eminyakeni ezivikela ukulahlekelwa, lapho abalingiswa beqaphela ukuthi uma ungazi ukuthi yini into, ukuyibiza ngokuthi uSteve kuyenza ingesabi kakhulu!
Ngokwabacwaningi baseNyuvesi yaseCalgary eCanada naseNyuvesi yaseCalifornia, eLos Angeles, uSteve akayena nhlobo umuntu oyi-aurora, ngoba akanawo umkhondo wezinhlayiya ezigcwele amandla eziqhuma emkhathini woMhlaba okwenziwa ama-aurora. Ngakho-ke, uSteve uyinto ehluke ngokuphelele, into engaqondakali, ikakhulukazi engachazwanga. Abacwaningi bakubize ngokuthi “ukukhanya kwesibhakabhaka.”
Ngakho-ke, ucabangani ngemuva kokufunda la maqiniso angajwayelekile futhi angaqondakali ngomhlaba? Zizwe ukhululekile ukwabelana ngemibono yakho efanelekile.
