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