Answer :
Final answer:
Positive feedback loops amplify system changes while negative feedback loops stabilize systems.
Explanation:
A positive feedback loop is the type of feedback loop that pushes a system to an extreme. It amplifies the initial stimulus, leading to a runaway effect if not counteracted by negative feedback. An example is the melting ice caps, where reduced ice cover leads to more heat absorption, further accelerating ice melt.
On the other hand, a negative feedback loop stabilizes a system, preventing it from reaching extremes. An example is the regulation of the Earth's climate through factors like the ice-albedo feedback and the Planck feedback, which counteract temperature changes to maintain equilibrium.
Understanding feedback mechanisms in the Earth's climate system is crucial for comprehending how environmental changes, such as melting ice caps, can trigger cascading effects.
