ENT-3003 Lecture Notes - Lecture 11: Dissolved Organic Carbon, Nitrogen Cycle, Water Cycle
Document Summary
Hydrologic cycle: water falling outside the watershed not be transported into the watershed. Consists of numerous processes that produce rocks and soils depends on the the tectonic cycle for energy and hydrologic cycle for water. Sedimentary- formed by deposited sediment compressed over time metamorphic- formed from another rock that has been altered due to high pressure/temp. Physical weathering- produces sediment like gravel, sand, and silt chemical weathering occurs when weak acids in water dissolve chemicals from rocks \ The initial chemical composition and speci cs of formation determine the chemical nature of rocks (temp. and pressure) the chemical and physical nature of the rocks in turn affects the elements released during weathering. Most carbon is stored within living organisms (terrestrial organisms) most in plants. Carbon occurs in the ocean is several forms dissolved co2. Industrial processes can now convert molecular nitrogen into compounds usable by plants.
