<P> Fold mountains form when two tectonic plates move towards each other at a convergent plate boundary . Fold mountains form from sedimentary rocks that accumulate along the margins of continents . When plates and the continents riding on them collide , the accumulated layers of rock may crumple and fold like a tablecloth that is pushed across a table , particularly if there is a mechanically weak layer such as salt . </P>
