Iipleyiti zeTectonic zezona zitena zingundoqo zokwakha zejoloji yoMhlaba, ziyafana nentsimbi entsonkothileyo eyenza umqolo wezakhiwo ezininzi esidibana nazo kubomi bethu bemihla ngemihla. Kanye njengokuba amacwecwe esinyithi enokubunjwa kwaye asetyenziswe ukwenza isakhelo esomeleleyo, iipleyiti zetectonic ziipleyiti ezinkulu zeLithosphere yoMhlaba ezidityaniswa njengejigsaw puzzle ukwenza iqokobhe langaphandle leplanethi yethu. Eli nqaku lijonge kubume beepleyiti zetectonic, ukubaluleka kwazo, kunye nobudlelwane bazo neengqikelelo zesinyithi kunye nentsimbi.
Yintoni iipleyiti zetectonic?
Iipleyiti zeTectonic zikhulu, iindawo ezinzima zeLithosphere yoMhlaba (uMaleko ongaphandle woMhlaba). Iipleyiti zidada kwi-asthenosphere ye-semifluid ephantsi kwazo, ezivumela ukuba zihambe kwaye zinxibelelane. I-Lithosphere yoMhlaba yohlulwe yangamacwecwe amakhulu kunye amancinci amancinci, kubandakanywa i-Pacific Plate, i-North American Plate, i-Eurasian Plate, i-African Plate, i-South American Plate, i-Antarctic Plate, kunye ne-Indo-Australian Plate.
Ukuhamba kwala macwecwe kuqhutywa ngamandla afana ne-mantle convection, plate pull, kunye ne-ridge thrust. Njengoko zihamba, zibangela izinto ezahlukahlukeneyo zokuma komhlaba, kuquka iinyikima, ugqabhuko-dubulo lwentaba-mlilo, nokusekwa kweentaba. Ukudibanisa phakathi kwala mapaneli kunokufaniswa nenkqubo yokwenza isinyithi, apho amacandelo ahlukeneyo adityaniswa, abunjwe kwaye aqhutywe ukuze enze isakhiwo esidibeneyo.
Imveliso yesinyithi isifaniso
Kumsebenzi wesinyithi, amagcisa asebenzisa ngobuchule iphepha lentsimbi ukwenza izinto ezisebenzayo nezihle. Badibanisa, bagobe kwaye bamise isinyithi ukufikelela kwiimilo ezinqwenelekayo, kufana neetectonic plates ezisebenzisanayo ukwenza imbonakalo yomhlaba. Ngokomzekelo, xa iipleyiti ezimbini ze<em>tectonic zingqubana, zenza iintaba, ngendlela efanayo nendlela abasebenzi bentsimbi abayila ngayo imizobo eyomeleleyo nentsokothileyo ngokubeka kunye nokuwelda amacwecwe esinyithi kunye.
Ngaphaya koko, njengokuba iintsimbi zinokuphinda zisetyenziswe kwaye ziphinde zisetyenziswe, iipleyiti zejoloji zihlala zibunjwa ngokutsha kwaye zitshintshwa ngeenkqubo zejoloji. Iizowuni zokuthoba, iindawo apho ipleyiti inyanzeliswa ngaphantsi kwenye, inokuthelekiswa nokunyibilika kunye nokubunjwa ngokutsha kwesinyithi, okukhokelela ekudalweni kweempawu ezintsha zejoloji ngokuhamba kwexesha.
Ukubaluleka kweepleyiti zetectonic
Ukuqonda iipleyiti zetectonic kubalulekile ngenxa yezizathu ezininzi. Okokuqala, badlala indima ebalulekileyo kwimisebenzi yokwakheka komhlaba. Ukushukuma kwala macwecwe kuphumela ekusasazweni kweenyikima zomhlaba kunye neentaba-mlilo. Imimandla ebekwe kwimida yeepleyiti, efana nePacific Ring of Fire, ithandwa kakhulu kwiziganeko zenyikima, nto leyo eyenza kube yimfuneko ukuba izazinzulu zifunde ezi ndawo ukuqikelela nokunciphisa iintlekele zendalo.
Okwesibini, iitectonic plates zinempembelelo kwimozulu yoMhlaba nakwizinto eziphilayo. Ukuhamba kwamacwecwe e-tectonic kukhokelela ekubunjweni kweentaba zeentaba, ezichaphazela iimo zezulu kunye nezinto eziphilayo. Ngokomzekelo, ukuphakanyiswa kwee-Himalaya kube nempembelelo enkulu kwimozulu ye-Indian subcontinent, ukudala imimandla ekhethekileyo yendalo.
Isishwankathelo
Ngamafutshane, iipleyiti zetectonic zibalulekile kwijoloji yoMhlaba njengoko iipleyiti zesinyithi zibalulekile kwihlabathi lesinyithi. Iintshukumo zabo zibumba umphezulu woMhlaba, zenza izinto zendalo, kwaye zinempembelelo kokusingqongileyo. Ngokufunda iipleyiti zetectonic, sifumana ukuqonda okubalulekileyo kwiinkqubo eziguquguqukayo ezilawula umhlaba wethu, okusivumela ukuba siqonde ibhalansi entsonkothileyo yendalo-efana nobugcisa obufumaneka kwisinyithi esinobuchule. Ukuqonda ezi zakhiwo zejoloji akuphuculi nje ukuqonda kwethu imbali yoMhlaba kodwa kusivumela ukuba silungiselele ngcono imingeni ebangelwa ziintlekele zendalo.
