Carbon EQ - 1
Geological carbon
- most carbon is stored in carbonate rocks, mainly limestone formed in ocean, but there is also shale and clay, which is created biologically
- sedimentary rock - formed in low-energy enviornments, where layers are deposited and built up over time.
- compression of layers create chemical reaction, creating carbon itself
Shale, Coal and other rocks: - made up to 330mmya
Ocean sequestration
- oceans are earth's second largest carbon store
Biological pump: - these move carbon dioxide to the ocean surface through phytoplankton and photosynthesis. they convert carbon dioxide into food for zooplankton
- most of carbon is recycled near the surface
Physical pump: - this moves carbon compounds to different parts of the ocean in downwelling + upwelling currents
Carbon cycle
- shows transfer of carbon through terrestrial, oceanic and atmospheric stores
- fluxes between each of the elements on landscapes vary and are measured in Pentagram's (Pg) and Gigatonnes (Gt)
- Sedimentary rocks + ocean sediments
-
Biological carbon
- on land, soil is the largest store of carbon. dead organic matter stores carbon for centuries before it breaks down and is taken up by plants, before being released into the atmosphere
-
-
Fossil fuel combustion
implications for climate: - rising mean global temp, more precipitation and evaporation, sudden shift in patterns, more extreme events, variation region to region
-
Geological processes
- geological carbon can also be released into the atmosphere through geological processes:
- carbon dioxide in atmosphere reacts with moisture to form
The greenhouse effects
- it regulates and alters the distribution of temp and precipitation
- earth's climate is driven by incoming short-wave radiation:
- 31% is reflected back into space
- 69% is absorbed by earths surface + oceans
