Open And Closed Systems Of Carbon And Water Cycles Flashcards
What is an open system
Boundaries are open to both and outputs of energy and matter
Carbon can move from a forest or peat bog to another store.
What is a closed system
Inputs and outputs of energy but no movement of materials are moved across the boundaries of systems
Finite amount of water on Earth
What is a system
Groups of objects and the relationship that bind them together
What are the major flows between stores
Pecipitation and evaporation
Drainage basins - open systems
Think inputs, processes, stores and outputs
Inputs: precipitation, energy from the sun
Processes: condensation , evaporation, evapotranspiration, stem flow, run-off, percolation, infiltration, groundwater flow
Stores: atmosphere, vegetation, cryospheric stores, oceans, rivers,acquirers and lakes
Outputs: rivers, human extraction, groundwater flow into a basin
