Facts about Earth can touch on geology, biology, and astronomy, among many other subjects. The surprising Earth facts in this episode of The List Show will hopefully give you a little more appreciation (and many more fun facts) about our planet. Erin shares a whole lot of facts about the planet Earth, from the etymology of the word earth to weird gravitational anomalies (and the reasons behind them). You’ll learn which type of organism makes up the majority of life on Earth, and which planet inspired albums by Joe Walsh and Marvin Gaye (hint: it isn’t Mars).
