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? A. Melting glaciers would add more water to the hydrosphere, making it wetter.
B. Melting glaciers would change the land around it, speeding up erosion.
C. Melting glaciers would let the uncovered air and land warm, which speeds up the melting.
D. Melting glaciers would mean more ice at its top, which would slow the glaciers melting.
