Study Notes
The Global Water Cycle
- A system is a set of interconnected components working together.
- The global water cycle is a closed system.
- The atmosphere, cryosphere, and hydrosphere are the main water stores.
- The cryosphere (glaciers and ice caps) holds the largest freshwater store.
- 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 a primary input into 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 the downward movement of water through soil and rock.
- Throughflow is the lateral movement of water within the soil.
- Groundwater flow is the slow movement of water through permeable rock.
- Surface runoff is water flowing over land when the ground is saturated or impermeable.
- Transpiration is water loss from plants through pores in leaves.
- Evaporation is water loss from surfaces; evapotranspiration includes water from plants.
- Interception is water caught by vegetation before reaching the ground.
- Melting ice triggering further ice melt is a positive feedback.
- Deforestation is a human activity altering the water cycle.
- Urbanization increases surface runoff and reduces infiltration.
