The zigzag shape of rock layers in mountains is primarily caused by the processes of tectonic activity, specifically folding and faulting. When tectonic plates collide, the immense pressure can cause the rock layers to deform instead of breaking. This deformation often results in the bending and folding of sedimentary rock layers, creating wave-like or zigzag patterns. Additionally, erosion and weathering can further accentuate these shapes by selectively wearing away softer rock layers, leaving behind more resistant rock, which may enhance the zigzag appearance.
