Web15 de set. de 2016 · As David says, stresses acting on a rock can be resolved into three principal stresses, one of which is vertical. The surfaces of maximum shear stress are failure surfaces (i.e. faults) that ... WebCompression squeezes rocks together, causing rocks to fold or fracture (break) (figure 1). Compression is the most common stress at convergent plate boundaries. Rocks that are pulled apart are under tension. Rocks under tension lengthen or break apart. Tension is the major type of stress at divergent plate boundaries.

http://en.dzkx.org/article/doi/10.6038/cjg2024M0056 WebWhen stress causes a material to change shape, it has undergone strain or deformation. Deformed rocks are common in geologically active areas. A rock’s response to stress depends on the rock type, the surrounding temperature, and pressure conditions the rock is under, the length of time the rock is under stress, and the type of stress.

Sometimes faults move when energy is released from a sudden slip of the rocks on either side. Most earthquakes occur along plate boundaries, but they can also happen in the middle of plates along intraplate fault zones.
