Earth Science - Gr. 3-7: Understanding Earth's Systems

Earth is broken down into four systems: atmosphere, geosphere, hydrosphere, and biosphere. These systems are all interconnected and help provide balance on Earth and in Earth’s ecosystems. Your readers learn about cycles associated with each system and how they benefit Earth. These books also discuss how people interact with each system and how human activities can negatively impact these systems. Relevant captions help your readers make connections between the main text and images.
