I. Objectives
a. Identify different processes that occur along the plate boundaries
b. Differentiating slab pull and ridge push mechanisms
c. Relate how these mechanisms cause earthquakes, volcanic eruption, and tsunami
II. Problem: How the different mechanisms in the mantle cause earthquakes, volcanic eruption, and tsunami?
III. Procedure
