False
question
What type of feedback maintains stability in a system, i.e. Keeps a system functioning
answer
Negative
question
If a system responds to input by moving further away from its equilibrium ____________ feedback has occured
answer
Positive
question
Best describes the condition of steady state equilibrium
answer
System inputs and outputs fluctuate around a stable average so the system does not move far from its average condition
question

answer
Positive, out of equilibrium
question
Increase in meltponds in Arctic is an example of
answer
Positive feedback because the meltponds absorb more solar energy than the ice did
