How does land cover change move carbon between the land, the atmosphere and the oceans?

Explain how land cover and its transformation function within the global carbon cycle as stores, sinks and sources of carbon
A QCE Geography Unit 3 answer on how land cover functions in the global carbon cycle. Covers carbon stores and fluxes, forests and soils as sinks, deforestation and peatland drainage as sources, blue carbon, and Australian and global cases including the Amazon and Queensland clearing.
