Faults are cracks in the earth's crust along which there is movement. These can be massive (the boundaries between the tectonic plates themselves) or very small. Fractures are simply cracks in the crust where there is no movement. Faults are classified according to the direction of relative movement along the fault.

why does oceanic plate usually subduct and not the continental plate
mikay2663
Oceanic crust is denser than continental crust. At a subduction zone, the oceanic crust usually sinks into the mantle beneath lighter continental crust. (Sometimes, oceanic crust may grow so old and that dense that it collapses and spontaneously forms a subduction zone, scientists think.)
