Biogeochemical cycles

Global cycles of chemical interactions among environmental compartments: ex. Biosphere (carbon cycle, water cycle, oxygen cycle etc.)

2

CO2 added to atmosphere from different sources

geologic inputs (volcanoes, ocean ridges), biological inputs (respiration), Human activities (deforestation fossil fuel burning)

3

CO2 removed from atmosphere

Geologic removal (chemical weathering of rocks; takes a long time). Biological removal (photosynthesis)
