Prime purpose of this lecture is to presentation on Plate Tectonics. To understand plate tectonics one must understand the dynamics involving the solid, rigid lithosphere which is floating on a in some measure molten asthenospherse. Plate tectonics can describe matching coastlines of South USA and Africa, along with matching geology for older rock units on the two continents. Paleontological facts supports plate tectonics along with plate motions. Movement of tectonic plates including relative movement regarding continents can explain the apparent wandering on the paleomagnetic pole over geologic time period.
