• plate boundaries

• seismic waves

• convection currents

• fault lines

• compression

• shear stress

• aftershock

This type of stress is at convergent boundaries, where rocks are squeezed together, causing them to fold or fracture.

• tension stress

• shear stress

• compression

• confining stress

This is the type of stress affecting a submarine or deep sea diver, where the force acts equally in all directions.

• shear stress

• compression

• tension stress

• confining stress

This is the type of stress at transform fault boundaries where forces slide past each other in opposite directions, tearing rocks apart.

• confining stress

• compression

• shear stress

• tension stress

This is the type of stress at divergent boundaries where tension causes rocks to pull apart and lengthen.
