What is the Plate Tectonics theory?
To put it simply, the theory of Plant Tectonics states that Earth’s crust and the outermost part of the mantle are mechanically connected to each other. This layer is broken into several plates that move about Earth’s surface. As they move about, they are constantly interacting with each other along their boundaries. It is the interactions along the boundaries that are responsible for most of the volcanic and earthquake activity that occurs on this planet. If you want a more detailed explanation, they I would suggest looking at the following web site: http://pubs.usgs.gov/publications/text/dynamic.html This is a United State Geological web site that describes the theory in a whole lot more detail than would really be practical here. (I spend a couple of hours talking about this theory in my classes.
