Answer:
Explanation:
Hard-shelled organisms absorbed calcium and carbonate iron and use them in making their hard shells which are calcium carbonate. When these organisms die, there shells are used in the formation of limestone rock. Limestone rocks are a huge store carbon. When acid rain reacts with limestone, these trapped carbon are released to the atmosphere thereby causing an Increase in atmospheric carbon.
Conclusively, the accumulation of limestone rock and subsequent reactions with acids such as acid rain has resulted in an increased atmospheric carbon throughout the years.
Atmospheric amount of carbon dioxide has increased in the last 550 million years which has affected the Earth's climate via global warming.
Given to enormous amount of limestone that has been produced from the shells of hard-shelled organisms, there has been an increase in the amount of carbon dioxide in the atmosphere.
Carbon dioxide can be broken down or released from Limestone via various means. One of such ways is when acid rain reacting with limestone. Carbon dioxide is released from Limestone when acid rain acts on it.
In essence, the abundance of Limestone rock has over the years led to increased level of atmospheric carbon dioxide.
Carbon dioxide is one of the major gasses that has contributed to global warming by creating what we call the greenhouse effect. This has resulted in climate change as extreme temperature are now being recorded including the melting of ice caps on a large scale.
Therefore, the increase in the production of Limestone from the shell of hard-shelled organisms has increased the level of atmospheric [tex]CO_2[/tex], and it has caused climate change through it's greenhouse effect on earth.
