What are feedback mechanisms are how do they impact climate?
What will be an ideal response?
Answer: Feedback mechanisms are numerous in all sorts of places in the Earth's subsystems. The student answer here should explain that a feedback is a natural reaction to change in the status of a system. Most feedbacks are negative feedbacks, therefore tending to dampen the swing of the subsystem away from equilibrium. However, some are positive. The student should illustrate feedback mechanisms with an example (e.g., the disappearance of ice that would decrease albedo).
