The Carbon Cycle - NASA Earth Observatory
Through a series of chemical reactions and tectonic activity, carbon takes between 100-200 million years to move between rocks, soil, ocean, and atmosphere in the slow carbon cycle. On average, 10 13 to 10 14 grams (10–100 million metric tons) of carbon move through the slow carbon cycle every year.
Carbon cycle - Understanding Global Change
Carbon cycles through the atmosphere, biosphere, geosphere, and hydrosphere via processes that include photosynthesis, fire, the burning of fossil fuels, weathering, and volcanism.
CHAPTER 1: OVERVIEW OF THE GLOBAL CARBON CYCLE
The global carbon cycle comprises a fast carbon cycle, having relatively rapid exchanges among the ocean, terrestrial biosphere, and atmosphere, and a slow carbon cycle, involving exchanges with geological reservoirs such as deep soils, the deeper ocean, and rocks.
Global Carbon Cycle - an overview | ScienceDirect Topics
The global carbon cycle refers to the exchanges of carbon within and between four major reservoirs: the atmosphere, the oceans, land, and fossil fuels.
