Up to this point, we have focused on what earthquakes are, how we detect them and how they are measured. Now we are going to start trying to answer that nagging question that everyone keeps asking - Why do they happen?
To answer this question we need to understand where they occur. In class today we discovered that there are patterns in their locations, but not always. We also highlighted the 3 major belts for seismic activity: Ring of Fire, Mid- Atlantic Ridge, and the Mediterranean-Himalyan Belt.
Tomorrow, we are going to work on how the plate tectonic theory all came about.
HOMEWORK! Complete the questions using your plate boundary map
