These sessions will discuss the overlying theory that explains the way geology operates. We will start with a discussion of the two processes that are responsible for the changes on the earth’s surface over the last 4.6 billion years. These changes are caused by destructive and constructive processes. It is now possible to answer questions that have concerned geologists for many years. How are mountains formed? Why do earthquakes and volcanoes occur where they do? Why are oceanic rocks different from continental rocks? What is the origin of continents? What is the origin of granite?
