Our planet is alive, and not just because it enables life to live here, but also the land on Earth is constantly shifting and moving. This time on The Children's Hour we learn about our earthquakes from science communicator and geologist, Dr. Wendy Rocks. Then we hear about volcanoes from Dr. Mousumi Roy. We explore what causes earthquakes and volcanoes, and how scientists can (or cannot) predict them. Plus hear a Kids Crew review of a new book about epic mythology: Greeking Out. Let's get shaking with The Children's Hour!
