the carbon cycle
increasing carbon in the atmosphere is becoming a problem for climate change, we need carbon to survive
stores of carbon - hydrosphere, lithosphere, atmosphere, n biosphere, pedosphere
-
-
the stores
marine sediments and sedimentary rocks - 100,000 billion metric tonnes - long term and largest

fossil fuel deposits - hydrocarbons like coal oil and gas are used and are so important, key cause of climate change
soil organic matter - rotting organic matter, deforestation and combustion release these stores of carbon into the atmosphere
atmosphere - increased in recent years, thus enhancing the greenhouse effect
