An old-fashioned scientific diagram illustrating 'The Four Reservoirs': Atmosphere, Biosphere, Geosphere, and Hydrosphere, with labeled arrows showing processes like Photosynthesis, Respiration, Combustion, Diffusion, and Sedimentation.

An old-fashioned scientific diagram illustrating 'The Four Reservoirs': Atmosphere, Biosphere, Geosphere, and Hydrosphere, with labeled arrows showing processes like Photosynthesis, Respiration, Combustion, Diffusion, and Sedimentation.

The Four Reservoirs: Draw four large boxes labeled Atmosphere (air), Biosphere (plants/animals), Geosphere (rocks/fossil fuels), and Hydrosphere (oceans). • The Flows (Arrows): • Photosynthesis: Arrow from Atmosphere to Biosphere. • Respiration/Decomposition: Arrow from Biosphere to Atmosphere. • Combustion: Arrow from Geosphere (fossil fuels) to Atmosphere. • Diffusion: Two-way arrows between Atmosphere and Hydrosphere. • Sedimentation: Arrow from Hydrosphere to Geosphere.
