Document Summary

Mountain that gave away due to weathering. Forcing: external or internal disturbance in a system. Hurricane erosion of beach and dune system. Response: the change we observe from perturbation. Recovery: it will recover but it is slow compared to the perturbation. Reaction time: the interval between a disturbance of change in controls and observabe. Relaxation time: the ensuing period of adjustment up to a new equilibrium or another. Resilience: ability to maintain or reestablish behavior following a disturbance or. Can come from internal or extrenal force morphological change threshold adjust stress-absorb stress. Eruption of a volcanoe is an internal force. Positive coupling: a change (increase or decrease) in one component leads to a change of the same direction in another component. Output of a system can influence continuing system operations. Information is returned to various points inthe system via pathways called feedback loops. Increasing co2 -> global warming -> increased evaporation -> increased water vapor -> warms atmosphere.
