This is a key to the Triangulation Exercise developed by Ortiz.

Simulations of Plate Tectonics
http://www.chathamcentralschools.com/hs/academic_dept/Science/Schaefer/graham%20cracker%20plate%20tectonics%20lab%20activity.pdf
The theory of plate tectonics states that the crust of the Earth is composed of 7 major plates and numerous smaller plates. These plates move on the top of the hot plastic upper mantle known as the asthenosphere. This theory also says that most of these plates are in motion, creating a variety of interactions at the plate boundaries. At the plate boundaries, plates may converge (collide), diverge (separate), or slide past each other in a lateral motion. In addition, some plates may appear to be inactivity. The purpose of this lab is to demonstrate interactions of plate boundaries.
My students are doing two labs today.
