This book was one of my favorites that I read because it's such a great, informative piece for children. It's a picture book that goes through informing about parts of our world. It starts with Earth's core and atmosphere, and then also explains space facts. There's information on our weather and seasons, and how fossils and rocks appear. It ends with our oceans and the biomes around the world. Such a good informational story that I would recommend to any teacher or parent.
