Laura LewisHost: Laura studied at Royal Holloway University of London and the Open University. She is passionate about science communication and has presented talks about Exoplanets at Oxford University and Imperial College London.

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. Join Laura to go through the ages and immerse yourself into the Geology of each era.
