How do scientist identify if a mountain if a fault-block or a folded mountain?

Question

details please

Answer 1

Fault-block or fault mountains are produced when near vertical faults fracture a section of continental crust which can then lead to high escarpments. The two types of block mountains are lifted and tilted. Lifted type block mountains have two steep sides exposing both sides scarps. Tilted type block mountains have one gently sloping side and one steep side with an exposed scarp.

A folded mountain or fold mountain is created when two tectonic plates hit each other straight on. This causes them to rise out of the earth.  Folded mountains make up some of the highest mountains in the world. Folded mountains commonly form along borders, where two continents are colliding. They tend to look like an accordion.
