Streams carry calcium ionsâ€”the result of chemical weathering of rocksâ€”into the ocean, where they react with carbonate dissolved into the water.
Through a number of chemical responses and tectonic task, carbon takes between 100-200 million years to go between stones, soil, ocean, and environment when you look at the slow carbon period. Every year on average, 10 13 to 10 14 grams (10â€“100 million metric tons) of carbon move through the slow carbon cycle. In contrast, human being emissions of carbon to your environment are regarding the purchase of 10 15 grms, whereas the carbon that is fast moves 10 16 to 10 17 grms of carbon each year.
The motion of carbon through the environment towards the lithosphere (stones) starts with rainfall.
Atmospheric carbon combines with water to create a weak acidâ€”carbonic acidâ€”that falls to your area in rainfall. The acid dissolves rocksâ€”a process called chemical weatheringâ€”and releases calcium, magnesium, potassium, or salt ions. Streams carry the ions into the ocean.
The merchandise of the effect, calcium carbonate, will be deposited on the ocean flooring, where it becomes limestone. (Photograph Â©2009 Greg Carley.)
The calcium ions combine with bicarbonate ions to form calcium carbonate, the active ingredient in antacids and the chalky white substance that dries on your faucet if you live in an area with hard water in the ocean.
