During ice ages,which of the feedbacks in the climate system plays a bigger role?

Question

Quizplus · Accepted Answer

Albedo plays a significant role during ice ages because as ice and snow cover expand, they increase the Earth's reflectivity, or albedo, causing more solar radiation to be reflected back into space rather than absorbed by the Earth. This process amplifies cooling, making albedo a critical feedback mechanism in the climate system during ice ages.
