W+C Cycles Feedback + Relationship

Question 1

Carbon Positive Feedback Example

Answer 1

• More CO2 In Atmosphere
• Global Temperature Rise
• Increased Ocean Temperature
• Dissolved CO2 Released by Oceans

Question 2

Carbon Negative Feedback Example

Answer 2

• Increase in CO2 in Atmosphere
• More Plant Growth
• More CO2 Absorbed

Question 3

Water Positive Feedback Example

Answer 3

• Increase in Global Temperatures
• Increase in Evaporation
• Increased Water Vapour in Atmosphere - More Clouds
• More Heat Trapped In

Question 4

Water Negative Feedback Example

Answer 4

• Increase in Global Temperatures
• Increase in Evaporation
• Increased Water Vapour in Atmosphere - More Clouds
• Less Sun In

Question 5

Examples of Interaction Between Water and Carbon Cycles

Answer 5

• Increasing atmospheric CO2 has warming effect - increased evaporation + therefore increased precipitation (DE increase)
• Volcanic eruptions release both CO2 and Water Vapour
• Photosynthesis requires both precipitation and CO2
• Decomposition releases CO2 and requires water
• Melting of permafrost releases CO2 and rises sea levels
• Acid rain + Ocean Acidification
