As arctic temperatures rise,summer sea ice and glacial melt accelerates; lighter color surfaces are thereby replaced with darker-colored surfaces leading to more absorption and surface heating.This is an example of a(n)________feedback.

Question

Quizplus · Accepted Answer

This is a positive feedback loop because it leads to a self-amplifying process. As the ice melts and darker surfaces are exposed, there is more absorption of sunlight and warming of the surface, which in turn leads to more melting and further exposure of darker surfaces. This cycle continues to reinforce itself and magnify the initial warming effect.
