Carbon and water cycle

Question 1

Example of positive feed back loop

Water cycle/ global temps

Answer 1

higher temperatures cause more ice to melt, so less solar energy is reflected and more is absorbed, leading to even higher temperatures

Question 2

Example of negative feedback loops

Water cycle, cloud coverage, temps

Answer 2

emperature increase causing increased rates of evapotranspiration and therefore increased cloud cover
- Increased cloud cover reflects solar radiation, reducing temperatures
