Széndioxidkörforgás

Széndioxidkörforgás is the process by which carbon dioxide (CO2) is exchanged between the atmosphere and the oceans, atmosphere, and land. This cycle is also known as the carbon cycle.

The process begins with the decomposition of organic matter in the environment, releasing CO2 into the atmosphere. Plants, on the other hand, absorb CO2 from the atmosphere through a process called photosynthesis, producing oxygen as a byproduct. This oxygen is released into the atmosphere, while the carbon is stored in the plant's tissues.

The oceans play a crucial role in the széndioxidkörforgás. They absorb CO2 from the atmosphere, which then reacts with water to form carbonic acid, bicarbonate, and carbonate. These compounds are incorporated into the skeleton of marine organisms such as coral and shellfish, which eventually sink to the ocean floor, removing the carbon from the cycle.

In addition to the oceans, the Earth's atmosphere also plays a key role in the széndioxidkörforgás. Weathering and erosion of rocks release CO2, while volcanic activity releases large amounts of CO2 into the atmosphere. The atmosphere also acts as a reservoir for CO2, storing it in the form of dissolved gas in ocean water and atmospheric carbon dioxide.

Human activities have disrupted the natural széndioxidkörforgás, primarily through the burning of fossil fuels, which releases large amounts of CO2 into the atmosphere. This has led to an increase in atmospheric CO2 levels, contributing to climate change. Understanding the széndioxidkörforgás is essential for managing this complex process and mitigating the impact of human activities on the environment.
