Question

whats the difference between a folded mountain and a fault-block mountain?

Answer 1

A fault line.These mountains form when faults or cracks in the earth's crust force some materials or blocks of rock up and others down. Instead of the earth folding over, the earth's crust fractures . It breaks up into blocks or chunks

In the creation of fold mountains, Earth's crust itself is warped into folded forms. Fold mountains are often associated with continental crust.
