A to je \u0161koda, nebo\u0165 tyto procesy jsou pom\u011brn\u011b fascinuj\u00edc\u00ed.\tV\u00a0podstat\u011b existuj\u00ed dva zp\u016fsoby, jak mohou poho\u0159\u00ed vzniknout. Oba jsou velmi rychl\u00e9, a v\u00a0sou\u010dasn\u00e9 dob\u011b se s\u00a0nimi ji\u017e prakticky nesetk\u00e1me, nebo alespo\u0148 ne v\u00a0takov\u00e9 m\u00ed\u0159e, v\u00a0jak\u00e9 se objevovaly v\u00a0minulosti.\tT\u00edm prvn\u00edm je pohyb litosf\u00e9rick\u00fdch desek. Pokud do sebe dv\u011b z\u00a0nich naraz\u00ed, jejich okraje se zdvihnou a vzniknou zpravidla vysok\u00e1 poho\u0159\u00ed. Typick\u00fdm p\u0159\u00edkladem jsou zde nejvy\u0161\u0161\u00ed hory planety, Himal\u00e1je, kter\u00e9 vznikly po n\u00e1razu indick\u00e9 desky do t\u00e9 eurasijsk\u00e9.\tJe jasn\u00e9, \u017ee takov\u00fdto proces je zna\u010dn\u011b destruktivn\u00ed, a proto bychom m\u011bli b\u00fdt r\u00e1di, \u017ee k\u00a0n\u011bmu v\u00a0sou\u010dasnosti nedoch\u00e1z\u00ed. Jeho v\u00fdsledkem jsou v\u0161ak prakticky ve\u0161ker\u00e1 vysok\u00e1 poho\u0159\u00ed, v\u010detn\u011b t\u011bch pob\u0159e\u017en\u00edch. Litosf\u00e9rick\u00e9 desky nejsou toti\u017e jen pevniny, n\u00fdbr\u017e tak\u00e9 dna mo\u0159\u00ed. A i ta se mohou srazit s\u00a0pevninou, co\u017e vytvo\u0159ilo poho\u0159\u00ed na z\u00e1padn\u00edm pob\u0159e\u017e\u00ed americk\u00e9ho kontinentu.\tTou druhou mo\u017enost\u00ed je sope\u010dn\u00e1 \u010dinnost. Zde se dostane pod tlakem magma na povrch, kde p\u0159i sv\u00e9m v\u00fdstupu nadzdvihne zemi. V\u00fdsledkem je vznik nov\u00e9ho kopce, p\u0159\u00edpadn\u011b, pokud je ohnisek v\u00edce, cel\u00e9ho poho\u0159\u00ed. V\u00a0na\u0161\u00ed republice t\u00edmto zp\u016fsobem vzniklo nap\u0159\u00edklad \u010cesk\u00e9 st\u0159edoho\u0159\u00ed. Tento typ pozn\u00e1me podle vulkanick\u00fdch hornin, kter\u00e9 zde nalezneme.\t\tJak u\u017e bylo \u0159e\u010deno, v\u00a0sou\u010dasn\u00e9 dob\u011b se tyto ud\u00e1losti v\u00a0takov\u00e9m rozsahu, jako v\u00a0minulosti, ned\u011bj\u00ed. A ani tehdy se nejednalo o b\u011b\u017enou z\u00e1le\u017eitost. Ne\u017e se zformovaly dne\u0161n\u00ed kopce a poho\u0159\u00ed do podoby, jak\u00e9 je zn\u00e1me dnes, uplynuly miliony let. A a\u010dkoliv to z\u00a0geologick\u00e9ho hlediska nen\u00ed a\u017e tak dlouho, z\u00a0lidsk\u00e9ho pohledu jde o nep\u0159edstaviteln\u011b dlouhou dobu.
