About this product

Discover the grand complexity of our Earth in this informative brochure on Earth's subsystems. Earth is not just a solid, rocky surface-it's a dynamic, living system consisting of four interrelated spheres: the Geosphere (the solid structure of Earth), that include in itself rocks, soil and landforms; the Hydrosphere (all water of Earth's oceans, lakes, rivers and glaciers); the Atmosphere - the layers of gases surrounding Earth that make life possible; and the Biosphere-that is, the realm of life of plants, animals, and microorganisms.

Every subsystem contributes to keeping life on Earth in a delicate balance. The interactions of these spheres control everything from the weather pattern to climate, and, even more importantly, the very survival of species. This brochure shows an in-depth look into how these systems work to form our planet's environment, resources, and its inhabitants.
