Unformatted text preview: Properties of the Hydrosphere and Lithosphere The Hydrosphere BOD, COD and Eutrophication The Lithosphere Typical Soil Horizons Cation Exchange Capacity Groundwater Summary and Conclusions I. The Hydrosphere Some Important Properties Hydrosphere – Principal Oceanic Currents II. BOD, COD and Eutrophication Increased sediments and nutrients cause increased plant and animal diversity The result is a meadow. Oxygen-Demanding Substances Substances that require O 2 for degradation. Chemical Oxygen Demand (COD) – O 2 required for abiotic degradation of a chemical over 5 days at room temperature. Biological Oxygen Demand (BOD) – O 2 required for microbial degradation of a chemical over 5 days at room temperature. Cyclic Process of Eutrophication Anthropogenic Sources of Nutrients There are numerous sources of plant nutrients. III. The Lithosphere – Soils Composition Typical Soil Soil Texture r Soils are composed of particles of a variety of sizes....
