Which type of stress causes rocks to bend and form folds?

Explanation:
Compressional stress pushes rocks together from opposite directions, causing them to shorten and bend. When rocks deform in a ductile, high-temperature environment, this pushing leads to folding rather than breaking, producing features like anticlines and synclines in mountain regions. Tensile stress pulls rocks apart, leading to extension and cracking or faulting; shear stress makes layers slide past one another, which can cause offset without forming folds; torsional stress twists rocks around a central axis, creating twisting deformation rather than simple folds.
