  1. The plate slowly begins to bend, because even though the plate material is hard, it can still be bent and folded over a very long period of time.
  2. The plate material from one plate breaks off into small pieces of rock that are about the size of tennis balls, because plates cannot bend.
  3. The plate material from one plate breaks off into large pieces of rock that are about the size of huge boulders, because plates cannot bend.
