Sonke siyazi, nokuba sizifundile ezinye iindaba, ukuba sizibonile ezindabeni okanye sizibonile, ukuba iinyikima ziyakwazi ukutshabalalisa iindlela, izakhiwo kunye nazo zonke iintlobo zokwakha. Kodwa, ukongeza, banokuguqula imeko-bume ... okanye neplanethi ngokwayo.
Kwaye ukuba uphando olutshanje lubonisa oko Iinyikima zitshintsha izinto ezolukiweyo kuqweqwe lomhlaba. Kuyamangalisa, akunjalo?
Uqweqwe lomhlaba
Kodwa kuqala, makhe sijonge ukuba ungakanani uqweqwe lomhlaba.
Uqweqwe lomhlaba luluhlu lwangaphandle lwamatye eplanethi. Ngokwenene kulungile kakhulu, malunga ne-5km ukutyeba kumgangatho wolwandle, ukuya kuthi ga kwi-70km kwiindawo zeentaba. Uqweqwe njengoko siyazi namhlanje lujikeleze iminyaka eyi-1700-1900 yezigidi ubudala. I-Oceanic, egubungela iipesenti ezingama-78 zomhlaba, kwaye ilizwekazi elinye lahlukile.
Yenzeka njani inyikima
Njengoko sisazi, iplanethi, ngokuthetha ngokwendawo, ijongeka ngathi iphazili ngenxa yamacwecwe eetectonic (abizwa ngokuba ngamacwecwe elithospheric) akhoyo. Xa uxinzelelo olukhulu lusakha phakathi kwabo, uyakhululwa, yiyo loo nto kubangela ukungcangcazela.
Inyikima ingaziguqula njani iipropathi zelastiki?
Iinyikima zingadala ezinye iikhilomitha ezininzi, kodwa ngoku iqela elikhokelwa nguAndrew Delorey, ovela eLos Alamos National Laboratory, kunye noKevin Chao, waseMassachusetts Institute of Technology (MIT) eCambridge, eUnited States. xa uxinzelelo lubangela ukuba iimpazamo ezimbini zihambe, Amandla akhutshwa ngohlobo lwamaza enyikima.
La maza, xa egqithela komnye ummandla wempazamo, alungisa i-elasticity evumela ukuba i-crust ikwazi ukumelana noxinzelelo. Ke, imeko yoxinzelelo lolwakhiwo nayo iyatshintsha, enokuthi ekugqibeleni ibangele inyikima entsha.
Umhlaba yiplanethi enamandla ngakumbi kunokuba unokucinga ekuqaleni.
