mountains occur at normal faults from the footwall being thrust upward along the hanging wall.

Question

fault-block
normal fault
folded

Answer 1

The statement you provided is more appropriately categorized under "fault-block" mountains.

In geological terms, fault-block mountains are formed through tectonic forces that cause large blocks of the Earth's crust to be uplifted due to normal faults, where the footwall moves upward relative to the hanging wall. This process can create rugged mountain ranges as these blocks are lifted and shifted.

"Folded" mountains, on the other hand, are formed primarily through compressional forces that cause the Earth's crust to bend and fold, rather than move past each other in a fault plane.

So, if you are looking to categorize your statement based on the choices given, it would be associated with "fault-block."
