What is the Carbon Budget?
The amount of carbon that's stored and transferred within the carbon cycle usually measured in petagrams
1 of 17
What are the impacts of the carbon cycle on the Land?
Formation and development of soil, Carbon in the form of organic matter introduces important nutrients and provides structure to the soil and is essential for plant growth and the production of food. Source of energy in form of wood and fossil fuels
2 of 17
What are the impacts of the carbon cycle on the Oceans?
Carbon can be converted to calcium carbonate, used by some marine organisms to build shells, and vital for coral growth. Basic food for phytoplankton, which is the start of an important food chain
3 of 17
What are the impacts of the carbon cycle on the Atmosphere?
Warms earth through Green house effect, allowing for life on earth. Increased emissions due to anthropogenic activity= climate change
4 of 17
Why is vegetation such an important factor in the Carbon Cycle and Global Climates?
Removes carbon dioxide and releases water and oxygen. Regions with dense vegetation experience high rates of photosynthesis and respiration. This increases levels of humidity and the amount of cloud cover which reflects UV radiation
5 of 17
What is the key connection between the carbon and the water cycle?
The absorption of carbon in rainwater
6 of 17
What causes rain to be acidic?
High concentrations of sulphur/carbon dioxide e.g.from emissions
7 of 17
What affect does acidic rainwater have?
Increases weathering, on contact with carbonate rocks it forms calcium Bicarbonate which is soluble
8 of 17
What is a water cycle feedback loop?
Melting ice reduces albedo, which causes more absorption of heat from sun, warming water causing further melting
9 of 17
What Political implications may rise from this Positive feedback loop?
No Arctic sea ice will affect trading routes, the exploitation of resources and settlement development
10 of 17
What positive effect is warmer temperatures having on the carbon cycle?
Higher temperatures have increased the growing season for plants and this has increased carbon absorption from the atmosphere
11 of 17
What negative effect is warmer temperatures having on the Carbon cycle?
Permafrost which is a major carbon store is melting, especially in Siberia
12 of 17
What is estimated about the amount of carbon stored in permafrost?
More carbon in the permafrost then there's currently in the atmosphere
13 of 17
Why is melting permafrost such a major carbon source?
The organic matter in permafrost starts to decompose as oxygen is introduced , bacteria involved in the decomposition produce carbon dioxide and methane as a by product, which escapes to the atmosphere
14 of 17
Why does melting permafrost pose such a huge threat?
It will produce a positive feedback loop where temperatures will increase along with melting
15 of 17
In what way are phytoplankton involved in a negative feedback loop?
Phytoplankton are microscopic plant-like organisms that live in water and photosynthesise absorbing CO2. Marine phytoplankton produce a substance called dimethylsulphide (DMS) that promote cloud formation over oceans, reflecting suns energy=cooling
16 of 17
What impact does cooling have on Phytoplankton?
Their numbers reduce
