Water/carbon cycle system frameworks Flashcards
What is a flow/transfer?
Form of linkage between a store and another that involves movement of energy or mass
Whats an input?
Addition or matter/energy into a system
What is a store/component?
Part of the system where energy mass is stored or transformed
What is a system?
Set of interrelated components working together
stores, flows and components
What is a model?
Simplified way of showing system
What is an isolated system?
No interactions with anything outside boundary
What is a closed system?
Have transfers on energy both into and beyond the system boundary but not matter
What is an open system?
Matter and energy can be transferred from the system across the boundary into the surrounding environment
What is positive feedback?
Effects of action are amplified by subsequent knock on effects
What is negative feedback?
Effects of action are nullified by subsequent knock on effects
What is dynamic equilibrium?
Balance between inputs and outputs and stores stay the same
What is a cascading system?
Where systems work together to form a chain
