This comprehensive set of posters illustrates key concepts in the study of ecology and the environment. The “Eco-Spheres” posters examine Earth's major systems and the continuous interactions among them. Five systems, or “spheres,” are presented: Biosphere (living things), Geosphere (land), Hydrosphere (water), Atmosphere (air), and Anthrosphere (humans and their creations). Photographs, diagrams, and text describe important features and relationships.
Each sphere is examined through a set of three posters: one describing the sphere itself and its interactions with other spheres, and two taking a closer look at the sphere's unique processes and characteristics. Fifteen 18” x 32” posters. © 2002.
