An orogenic event takes millions of years to create a fold mountain. Fold occurs when one or a stack of originally flat and planar surfaces such as sedimentary strata are bent or curved as a result of permanent deformation. Fold mountains are mountain that are mainly formed by the effects of folding on layers within the upper part of the earth s crust before either plate tectonic theory developed or the internal architecture of thrust belts became well understood the term was used for most mountain belts such as the himalayas the term is still fairly common in physical geography literature but has otherwise.
Over time material and sediment is deposited in large geosynclines depressions in the sea.
To find out how fold mountains form and how they are linked to plate tectonics. Watch the video to the right hand side on how fold mountains are formed. Fold mountains are formed from sedimentary rock. The depressions form the valleys.
