Water Cycle Flashcards
What is a flow/ transfer?
Elements moving around the system
What is an input?
The addition of matter and/or energy into a system
What is a store/component?
Elements being stored in the system
What are elements?
The things that make up the system
What are attributes?
The perceived characteristics of various elements
What are relationships?
Association which occur between elements and attributes
What is an isolated system?
No interactions outside the system boundaryNo input or output of energy or matter
What is a closed system?
There are no inputs or outputs of the system. Matter is confined to the system, but energy may enter or exit.
What is a open system?
Where matter and energy can be transferred from the system across the boundary into the surrounding environment
What is dynamic equilibrium?
When there is a balance between inputs and outputs of the system
What is positive feedback?
Where the effects of an actions are amplified or multiplied
What is negative feedback?
where the effects of an action are nullified
What is cascading system?
A chain of systems
What is a model?
A way of simplifying or representing a complex reality
What is a System?
A model which helps explain relationships within a unit. It consists of a number of components all linked together
What is a cycle?
A continuous system

Where are a majority of lakes found?
a linear formation along the Tropic of Cancer
Where are lakes quite common?
Canada and North America
Where are less lakes found?
areas of little precipitation
Where are drainage basins found?
a linear formation especially along the Tropic of Cancer and the Tropic of Capricorn
Evapouration
Water turns straight to water vapour
Sublimation
Ice turns directly to water vapour
