<P> Carbon dioxide is removed from the atmosphere primarily through photosynthesis and enters the terrestrial and oceanic biospheres . Carbon dioxide also dissolves directly from the atmosphere into bodies of water ( oceans , lakes , etc . ) , as well as dissolving in precipitation as raindrops fall through the atmosphere . When dissolved in water , carbon dioxide reacts with water molecules and forms carbonic acid , which contributes to ocean acidity . It can then be absorbed by rocks through weathering . It also can acidify other surfaces it touches or be washed into the ocean . </P>
the process by which trees remove carbon from the air and store it in their biomass is known as
photosynthesis
