Physical 1: Water And Carbon Cycles Flashcards
What are the 4 components of a geographical system
Inputs
Outputs
Flows/ transfers
Stores
What is an open system
Has external inputs and outputs
What is a closed system
No transfer of matter beyond system boundaries
What 4 systems store water
Lithosphere
Hydrosphere
Cryosphere
Atmosphere
What are the main changes of magnitude of water cycle stores
Precipitation
Evaporation
Condensation
Infiltration
Percolation
Sublimation
Interception
Overland flow
Throughflow
Groundwater flow
What is a drainage basin
An area of land drained by a river and it’s tributaries
What is the water balance equation
Precipitation = tot runoff + evapotranspiration +/- storage
What are the main carbon transfers

Respiration
Decomposition
Combustion
Weathering
What are the physical causes of change in the carbon cycle
Natural climate change
Wild fires
Volcanic activity
