In this class we will take a trip through geological time, from the formation of the Earth until the present day.  We will examine the main events of each geological era and period. We will look at how the history of the Earth is divided by mass extinctions, abrupt climatic change and other factors. We will also examine how the age of rocks are investigated using techniques such as radioactive dating and index fossils.
