Explaining Plate Boundaries

There are three types of Plate Boundaries: 1) Convergent (Plates move apart) 2) Divergent (Plates move together) 3) Transform (Plates slide past each other) The first two are relatively easy to demonstrate, but transform boundaries can be confusing to students of all ages.
