Nutrient Cycles: We are but stardust… Every atom within us is on a journey… “Odyssey” – part one – by Aldo Leopold Other planets can move matter about… Great Red Spot on Jupiter Wind Storms on Mars Volcano on Io …but as the only planet that contains water in its liquid state… … Earth is the only planet that can effectively move large amounts of solid material from one place to another. Case in Point… Encontras do Aguas, Manaus, Amazonas, Brasil The Andes Mountains are washed away… So too are the Guinea Highlands The Result: Sandy,quartz sediment Silty, volcanic sediment All washes down to the Atlantic Ocean The Upshot Underwater view of deep ocean sediment fan off Amazon. Where were these sediments before? A. P.E.S. digression http://www.sciencecodex.com/biogeochemistry_at_the_core_of_global_environmental_s olutions Major Biogeochemical Cycles on Planet Earth Water (Hydrologic) Cycle Carbon Cycle Nitrogen Cycle Oxygen Cycle Sulfur Cycle Phosphorus Cycle Water Cycle – the driver for all other cycles Carbon Cycle LIFE & LIMESTONE Nitrogen Cycle N-Cycle: Aquatic Science application Oxygen Cycle Aquatic O – cycle Sulfur Cycle Phosphorus Cycle Why is it important that these cycles be kept in balance? How do we throw them out of balance? Aquatic Science Biogeochemical Review Game With 2-3 classmates, create the following… - a board game that reviews the inputs, reservoirs, and outflows of each biogeochemical cycle. Must cover the movement of each cycle, the reservoirs, and anthropogenic effects. Game is due for teacher grade on Tuesday, 6 September, 2011.
