How does elastic rebound theory explain when earthquakes occur? What will be an ideal response?
Where the rocks on the opposite side of a fault are on pieces of crust that are moving in different
directions, the rocks are initially locked in place by their strength and friction. The rocks do not move,
but they do deform. As the pressure builds, the strength of the rocks is eventually exceeded. They
rebound to their original shape, but the crust on either side of the fault has moved to a new location.
