When rock layers are squeezed horizontally during continental collision, they tend to bend rather than break. This bending creates folded structures, with features like anticlines and synclines that form in mountain belts. So “folded” best describes rock deformation from compression.

Faults are fractures where rocks break and slide, which is a different response to stress. Volcanic features come from magma and eruptions, not from compression-induced bending. Uplifted plains describe vertical movement that isn’t the bending of layers associated with folding.
