Marcus read that systems provide feedback, or the return of information. Feedback can either cause a change in the system or keep it stable. Melting glaciers are an example of positive feedback. Why is this considered positive feedback

melting glaciers would let the surrounding air and land get warmer which would cause the glacier to melt faster.

Explanation:

A positive feedback causes a system to remain stable or causes a change in the system. It is the return of the information to all.

In the context, melting of the glacier is considered as a positive feedback because as the glacier melts it causes the land and the surrounding air to get warmer which makes the glacier to melt at a faster rate.
