Question

what kind of feedback loop pushes a system to an extreme? melting ice caps is an example of this. positive negative

Explanation:

Positive feedback loops amplify changes, pushing a system further in the direction of the initial change. Melting ice caps reduce albedo (reflectivity), leading to more solar energy absorption, which causes more warming and more ice - cap melting, an example of a positive feedback loop. Negative feedback loops counteract changes to maintain stability.

Answer:

positive
