Orogenese

Orogenese (eller et orogent bælte) skabes, når en kontinental plade presses sammen. Dette gør, at jordens litosfære (skorpe og øverste del af kappen) smuldres og skubber en del af pladen op. Resultatet er en eller flere bjergkæder. Normalt sker dette, når to eller flere kontinenter kolliderer. Nogle eksempler på bjergkæder er Himalaya, Alperne og Appalacherne.

Her er et enkelt eksempel på hvordan er fjeldkæde bliver til.
