What is the procedure/variables for the plate tectonics lab

The Theory of Plate Tectonics states that the crust of the Earth is composed of seven major

plates and numerous smaller plates. These plates "ride" on the hot plastic upper mantle called

the asthenosphere. This theory also says that most of these plates are in motion, creating

a variety of interactions at the plate boundaries. As plate boundaries, plates may converge,

diverge, or slip (lateral) past each other in a horizontal motion. In addition, some plates may

appear to be inactive.
