Question

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

Answer 1

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

Step-by-step 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.
