GeographyThe Operation and Importance of the Hydrological CycleA2/A-levelEdexcel Created by: belle-madeleineCreated on: 05-12-17 15:14 Systems Approach System approaches study hydro logical phenomena by looking at the balance of inputs and outputs and how water is moved between stores by flows 1 of 13 Stores Reservoirs where water is held, such as the oceans 2 of 13 Fluxes The rate of flow between the stores 3 of 13 Processes The physical mechanisms that drive the fluxes of water between the stores 4 of 13 Cyrosphere Areas of the Earth where water is frozen into snow or ice 5 of 13 Blue Water Water is stored in rivers, streams, lakes and groundwater in liquid form 6 of 13 Green Water Water stored in the soil and vegetation 7 of 13 Precipitation The movement of water in any form from the atmosphere to the ground 8 of 13 Evaporation The change in state of water from a liquid to a gas 9 of 13 Residence Time The average time a water molecule will spend in a reservoir or store 10 of 13 Fossil Water Ancient, deep groundwater from former pluvial periods 11 of 13 Transpiration The diffusion of water from vegetation into the atmosphere, involving a change from a gas to a liquid 12 of 13 Groundwater Flow The slow transfer of percolated water underground through pervious or porous rocks 13 of 13
