Top processes

Fossil and geologic carbon exchange

2 steps

Mineral weathering and parent material

2 steps

Silicate weathering rate control and CO2 drawdown

2 steps

Bicarbonate and dissolved silica are exported in drainage water to rivers
Weathering consumes atmospheric CO2 (roughly 0.1-0.3 Gt C per year globally for silicates)

Soil inorganic carbon: pedogenic carbonate formation and dissolution

2 steps

Weathering, erosion and sediment transport

1 step

Chemical weathering dissolves silicates and carbonates, consuming Carbon dioxide

Ocean carbon exchange and burial

1 step

Carbonate chemistry converts CO2 to bicarbonate and carbonate

Show 3 more processes

Base cation cycling (calcium, magnesium, potassium, sodium)

1 step

Mobile anions (nitrate, sulfate, bicarbonate) carry cations out in drainage

Pedogenic carbonate accumulation and calcrete formation

1 step

Evapotranspiration removes water and CO2 degasses, so Ca2+ + 2HCO3- precipitates as CaCO3

Living soil system
