What is Carbon Cycle: Stores, Flows & Climate Feedbacks?
This topic examines the global carbon cycle, including the major stores of carbon (e.g., atmosphere, oceans, biosphere) and the flows between them. It investigates the impact of human activities, particularly the burning of fossil fuels, on the carbon cycle and the implications for climate change. The topic also explores the concept of climate feedbacks, both positive and negative.
Board notes: A key topic for AQA, Edexcel, and OCR, with strong links to climate change. AQA focuses on the concept of the carbon budget. Edexcel requires an understanding of the role of carbon in supporting ecosystems. OCR often asks students to evaluate the effectiveness of different climate change mitigation strategies.
Step-by-step explanationWorked examples
Worked example 1: Core method
To explain the concept of a positive feedback loop in the context of climate change, a student could use the example of melting permafrost. As global temperatures rise, permafrost in the Arctic thaws, releasing large quantities of methane, a potent greenhouse gas. This leads to further warming, which in turn causes more permafrost to melt, creating a self-reinforcing cycle.
Worked example 2: Exam variation
Now change one detail in the question and keep the same structure: name the Carbon Cycle: Stores, Flows & Climate Feedbacks idea being tested, show the method or evidence, then explain why it answers the command word. This helps A-Level Geography students avoid memorising one surface pattern.
Worked example 3: Mark-scheme check
Finish by checking the answer against marks: one point for the correct Carbon Cycle: Stores, Flows & Climate Feedbacks idea, one for accurate working or evidence, and one for a precise final statement. If any step is vague, rewrite it before moving to timed practice.
Mini lesson for Carbon Cycle: Stores, Flows & Climate Feedbacks
1. Understand the core idea
This topic examines the global carbon cycle, including the major stores of carbon (e.
Can you explain Carbon Cycle: Stores, Flows & Climate Feedbacks without copying the notes?
2. Turn it into marks
To explain the concept of a positive feedback loop in the context of climate change, a student could use the example of melting permafrost. As global temperatures rise, permafrost in the Arctic thaws, releasing large quantities of methane, a potent greenhouse gas.
Underline the method, evidence, or command-word move that would earn credit in A-Level Physical Geography.
3. Fix the likely mark leak
Watch for this mistake: Confusing the short-term and long-term carbon cycles.
Write one correction rule before doing another practice question.

Frequently asked questions
What is the difference between the greenhouse effect and global warming?
The greenhouse effect is a natural process where certain gases in the atmosphere trap heat, keeping the Earth warm enough for life. Global warming is the enhancement of this effect due to the increase in greenhouse gas concentrations from human activities, leading to a rise in global average temperatures.
What are some of the strategies for mitigating climate change?
Strategies for mitigating climate change include reducing greenhouse gas emissions (e.g., by switching to renewable energy sources and improving energy efficiency), and enhancing carbon sinks (e.g., through afforestation and carbon capture and storage).
