Gary Lewis, GEOetc.com
A place to learn about geology for teachers, students, rock hounds, and geology enthusiasts - that comes out on Fridays!
Gary Lewis is an Australian-born geologist who loves to share his passion for all things 'geology'. In the GEO podcast, Gary takes you on a journey to learn about rocks, minerals, earthquakes, volcanoes, glaciers and so much more.
It does not matter if you have no experience in geology, Gary will help you to understand the fundamentals of our planet so you can have a greater understanding about when you see when visiting your backyard, your local creek, cliff or beyond.
You can also join Gary as he runs Field Adventures (specialist travel experiences) to see parts of the world through the eyes of a passionate Earth scientist. Find out more at www.geoetc.com.
