Geographers classify the fold mountains into ‘young fold mountains’ are the ‘old fold mountains’ depending upon the age of the mountains

2. Block Mountains: Block mountains or horsts are also formed due to plate tectonics when the two plates move apart. Some parts of the Earth are pushed upward and others collapse down. The uplifted blocks are known as block mountains or horsts while the lowered blocks are called grabens. The examples of block mountains are the Rhine valley, Vindhya and Satpuras in India and the Vosges mountain in Europe.
