Carbon Cycle

The carbon cycle refers to the continuous movement of carbon atoms between the Earth's atmosphere, oceans, soil, plants, animals, and geological formations. It is a crucial part of the Earth's climate system and involves the exchange of carbon dioxide (CO2) and other carbon compounds. The cycle can be summarized as follows: carbon is released into the atmosphere through processes like respiration, volcanic eruptions, and combustion of fossil fuels. Plants absorb CO2 during photosynthesis, which is then stored in their tissues and released back into the atmosphere through respiration and decomposition. Animals consume plants and each other, incorporating carbon into their bodies. When plants and animals die, their carbon is returned to the soil or oceans, where it can be stored for long periods. Over geological timescales, carbon can be sequestered in rocks and fossil fuels, or it can be emitted back into the atmosphere through processes like weathering and the combustion of fossil fuels. Understanding the carbon cycle is essential for predicting how human activities, such as deforestation and burning fossil fuels, affect global climate patterns.
