Tensional stress.
Compressional stress.
Earthquakes infrequently occur away from plate boundaries. Most earthquakes occur at plate boundaries because of the stress caused by the interacting plates.
Volcanoes typically occur at two different types of plate boundaries. These two plate boundaries are: the diverging plate boundary where plates separate, and the converging plate boundaries where one plate is beneath another one at subduction zones.
divergent plate boundaries are associated with normal faulting. Thus there is a horizontal least compressive stress, vertical most compressive stress and a intermediate horizontal stress. All stresses are orthoganal to each other.

stress on rocks is greatest
divergent plate boundaries are associated with normal faulting. Thus there is a horizontal least compressive stress, vertical most compressive stress and a intermediate horizontal stress. All stresses are orthoganal to each other.
Subduction, is when one plate is pushed down into the magma, by the other plate sliding over the top.
Compressional stresses occur at convergent plate boundaries.
The type of stress that causes rocks to pull apart is a tension stress. It is the major type of stress found in divergent plate boundaries.
The movement of the plates relative to one another much greater stress along faults than is typically found away from plate boundaries.
