Carbon cycle

• lithosphere percentage

  99.9 %
• hydrocarbon percentage

  0.0004 %
• hydrosphere

  second largest store

  0.04 %
• cryosphere

  less than 0.01 %
• biosphere

  0.0004 %
• atmosphere

  0.001 %
• combustion

  releasing carbon from the lithosphere (hydrocarbons) into the atmosphere by burning them

  naturally: occurs via wildfires
• types of sequestration

  ocean

  sediment

  vegetation
• carbonation

  where co2 reacts with water vapor to form acid rain (carbonic acid) which erodes and dissolves rock surfaces
• affect magnitude

  sere scale:

  • photosynthesis
  • respiration
  • combustion
  • weathering
  • decomposition
• land use change

  removal of vegetation

  concrete production levels -> 2016 there was 2.2 bn tons produced which accounted for 8 % of global emissions
