Carbon cycle

/ˈkɑrbən ˈsaɪkəl/ noun

Definition

The biogeochemical cycle that describes how carbon moves between the atmosphere, oceans, land, and living organisms through processes like photosynthesis, respiration, and combustion. It includes both short-term biological processes and long-term geological processes.

Etymology

From Latin 'carbo' meaning 'charcoal' or 'coal' and Greek 'kyklos' meaning 'circle.' The concept developed in the 19th century as scientists began understanding how carbon moved through different Earth systems.

Kelly Says

The carbon cycle operates on multiple timescales simultaneously - from seconds during photosynthesis to millions of years in rock formation! Human activities have dramatically accelerated the release of carbon that was stored over geological time, disrupting the natural balance.
