The carbon cycle describes the continuous natural movement of carbon between which of the following components of Earth’s environment?
Explanation
The carbon cycle describes the continuous natural movement of carbon atoms between several major components of Earth’s environment, including the atmosphere, where carbon exists largely as carbon dioxide gas, living organisms, which absorb and release carbon through processes like photosynthesis and respiration, the oceans, which absorb and store significant amounts of dissolved carbon dioxide, and soil, which stores carbon within organic matter and various rock formations. This ongoing cycling of carbon between these different interconnected reservoirs helps maintain a relatively balanced overall carbon concentration within Earth’s atmosphere and broader environment. Human activities, particularly the large-scale burning of fossil fuels, have significantly altered the natural balance of this cycle in recent history, contributing to rising atmospheric carbon dioxide levels.
