Soil Orders of the World, Wiley (more info)
Seven different soil orders are pictured with respective horizon profiles. Alfisols, ultisols, mollisols, spodosols, vertisols, oxisols, and aridisols are represented on a world map. Inceptisols, entisols, andisols, and gelisols are left off the map. The animation is useful in correlating global temperature and precipitation patterns with soil horizon.
