Flashcards in Chapter 1 - Water & Carbon Cycle - Complete Deck (157)
Energy entering the system
Energy leaving the system
Energy is stored in the system
Energy moving around the system
From one store to another
Boundary/limit of the system
Define open system?
The system has inputs and outputs of energy
Define closed system?
The system has no inputs or outputs of energy
Define dynamic equilibrium?
There is a balance between the inputs and outputs of energy
Define positive feedback?
When the effects of an action are amplified by other knock-on effects
Define negative feedback?
When the effects of an action are nulllified by other knock-on effects
Characteristics of the elements that may be perceived and measured
Associations that occur between elements and attributes
Name the 6 spheres?
- Atmosphere - Air around us
- Lithosphere - Earth/land
- Cryosphere - Ice/glaciers
- Biosphere - Plants/animals
- Hydrosphere - water
- Pedosphere - soil/ground
Define cascading system?
Output of one system is the input of the next system
Solid --> Liquid
Liquid --> Solid
Solid --> Gas
Gas --> Solid
Gas --> Liquid
Liquid --> Gas

Define drainage basin?
Is an area of land drained by a river and its tributaries.
Define the boundary of a drainage basin?
Are drainage basins open or closed systems?
Define 1 input of water into a drainage basin?
- PRECIPITATION(rain, snow, hail, dew, frost)
Define 5 stores of water in a drainage basin?
- INTERCEPTION (Vegetation intercepts rainfall)
- VEGETATION STORAGE (Water stored in plants)
- SURFACE STORAGE (puddles, ponds, lakes)
- GROUNDWATER (aquifers, water table)
- CHANNEL (river, stream)
