The cycle where ice melt exposes dark water and leads to more warming is called?

• A. Feedback
• B. Amplification
• C. Albedo effect
• D. Damping

Answer: (A)

This is a feedback loop in the climate system. When warming causes ice to melt, darker water or land is exposed, and these surfaces absorb more sunlight because they have lower reflectivity (albedo). That extra absorption leads to more warming, which melts more ice, exposing even darker surfaces, and so on. This self-reinforcing cycle is a positive feedback, where the outcome amplifies the initial change. The general term for this kind of process is feedback. The mechanism behind it is the albedo effect, but the looping nature is captured by the term feedback. Damping would reduce changes, and while albedo describes the reflectivity change, it doesn’t name the looping, and amplification isn’t the standard label for this specific climate loop.
