Physical geography: Water and carbon cycles: Systems concept. 0.0 / 5 ? GeographyWeather systemsA2/A-levelAQA Created by: ria_needs_to_revisemoreCreated on: 07-11-18 10:38 What is a open system ? Systems that have external inputs and & outputs of energy & matter. 1 of 9 What is a closed system? A system that transfers energy into and outside of the system boundary, does NOT transfer matter. 2 of 9 What is an isolated system? They have no interaction with anything outside of the interaction boundary. No input of energy or matter. 3 of 9 Identify one characteristic of systems Function in the same way- involves inputs and outputs of material (energy/or matter). 4 of 9 identify one incorrect charcteristic of systems Systems accuratley show the reality of what is happening in systems. 5 of 9 Define positive feedback. Enhances and effect, which has an impact on the process- leading to a "SNOWBALL EFFECT." 6 of 9 Define negative feedback. Decreases the level of change, by reducing soem of the inputs. 7 of 9 Define dynamic equillibrium The state of balance in a system, where both the level of inputs and outputs are equal. 8 of 9 Idenitfy one factor that can cause disbalance in the system. Large storm events- storm surges. 9 of 9
