Study Notes
Water Systems Overview
- A system is a set of interconnected components working together as a whole.
- The global water cycle is a closed system.
- The main water stores are the atmosphere, cryosphere (glaciers & ice caps), and hydrosphere.
- The cryosphere holds the largest store of freshwater on Earth.
- A drainage basin is the land area drained by a river and its tributaries.
- The boundary of a drainage basin is called a watershed.
- Precipitation is the main input to a drainage basin.
- Outputs include evaporation, transpiration, and river discharge.
- The water table is the upper level of saturated ground.
- Infiltration is water entering the soil.
- Percolation is water moving downward through soil and rock.
- Throughflow is water moving laterally within the soil.
- Groundwater flow is slow water movement through permeable rock.
- Surface runoff is water flowing over land surfaces when saturated.
- Transpiration is water lost from plants through leaf pores.
- Evaporation involves water loss from surfaces; evapotranspiration includes water loss from plants.
- Interception is water caught by vegetation before reaching the ground.
- Melting ice triggering further melting is a positive feedback loop.
- Deforestation is one human activity altering the water cycle.
- Urbanization increases surface runoff and decreases infiltration.
