Which type of boundary typically leads to the formation of folded mountains?

The formation of folded mountains is primarily associated with convergent boundaries. This type of boundary occurs when two tectonic plates collide, forcing one plate to be pushed upwards while the other may be forced downwards. This intense pressure and the resulting compression lead to the buckling and folding of the Earth's crust, creating mountain ranges. The process typically involves continental crust, where the collision can result in the uplift and formation of diverse terrains characterized by complex structures of old, folded rock layers.

In contrast, divergent boundaries are where plates move apart, generally creating new crust rather than forming mountains. Transform boundaries involve plates sliding past each other, leading to earthquakes but not directly resulting in mountain formation. Subduction zones, while capable of creating significant geological features, often result in volcanic arcs and trenches rather than folded mountains. Therefore, the distinct geological processes at convergent boundaries make them the primary contributor to the development of folded mountain ranges.
