This Earth science resource enables students to view Earth's four spheres--the geosphere, hydrosphere, biosphere, and atmosphere. The visualization is introduced by a paragraph that defines the four spheres. Below the paragraph, there is an image of a globe that a viewer can animate by clicking on it. The globe separates into four globes, each of which shows one sphere and is labeled with the appropriate sphere name. The animation contains a legend to explain the color coding used. Controls allo
