Document Summary
3. in the long-term reservoir atmospheric carbon dioxide reacts with water and minerals in rocks to form calcium bicarbonate which enters rivers and ends up in the ocean where it becomes shells of various marine organisms. When these organisms die the shells accumulate on the ocean floor and are eventually transformed into rocks and petroleum. Over millions of years this transformed material is buried at depths of thousands of feet and the heat and pressure melts the rocks and converts the carbonate back to carbon dioxide. Some of these rocks become part of volcanoes and the carbonate is released as carbon dioxide via volcanic eruptions. There are two main ways in the short-term reservoir that carbon dioxide is removed from the atmosphere and enters the ocean. 2. discuss in detail the long term c cycle. The whole long term carbon cycle takes more than 100 thousand years.
