What are the ORIGINS of carbon on Earth?

- interior of the Earth (from within the mantle - semi-molten layer)

- plate boundaries (from mantle. Moves up through due to volcanic eruptions)

- stores such as biomass and oeans

- carbon removal (atmosphere/photosynthesis/when locked up in sedimentary rocks)

Carbon Stores

LITHOSPHERE

- crust and upper mantle

- inorganic form (fossil fuels and limestone)

- also organic form in humic substances (decaying matter)

stores...

- peat

- fossil fuels

- soil

- marine sediments (sedimentary rocks)

HYDROSPHERE

- oceans - dissolved carbon dioxide

- organisms like fish and plankton and some plants

stores...

- surface level

- intermediate layer

- living organic matter

BIOSPHERE

living part

- animals

- peat

- living vegetation

- soil humus

- plant litter

ATMOSPHERE

- carbon dioxide as a gas (control's Earth's temperature)

- atmospheric carbon dioxide is increasing (Mauna Loa Curve)

- caused by human activities releasing carbon dioxide into the atmosphere
