Negative Feedback in Systems: Characteristics and Impact

Play an AI-generated podcast conversation about this lesson

What is the impact of negative feedback in a river channel?

Enlarges the channel and reduces velocity (correct)

Increases erosion and reduces channel size

Constricts the flow and decreases velocity

Decreases erosion and increases channel size

How does positive feedback affect warming temperatures and global climate change?

Reduces the overall warming trend and stabilizes the planet

Amplifies temperature rise through reduced albedo effect (correct)

Stabilizes temperatures and maintains the albedo effect

Leads to cooling temperatures and increased ice/snow formation

Which characteristic best describes negative feedback in a system?

Increases response or stimulates processes

Encourages changes in the system

Drives the system towards extremes

Equals stability and enables self-regulation (correct)
