October 12, 2007 GEOG 1011-010 Chemical weathering applies when the atmospheric CO2 dissolves in raindrops, making the acidic. The rocks exposed at the surface undergo a chemical attack known as chemical weathering. This weathering in soils or organic carbon in sedimentary rocks reacts with oxygen, releasing carbon dioxide into the atmosphere. Mining, pumping and combustion of fossil fuels accelerate the weathering process. The CO2 concentration of the atmosphere changes continuously in response to changes in the flux of carbon. As we can see now, the atmospheric concentration of CO2, which is directly related to greenhouse gases, has been steadily increasing. However, in both carbonate and silicate weathering, the products are transported to rivers and ultimately to the oceans, which proves important to balance the carbon cycle. The reason carbonate weathering does not lead to the net removal of CO2 can be solved by setting carbonate weathering and carbonate precipitation equal to each other
