The Slow Carbon Cycle. Through a series of chemical reactions and tectonic activity, carbon takes between 100-200 million years to move between rocks, soil, ocean, and atmosphere in the slow carbon cycle. On average, 10 13 to 10 14 grams (10–100 million metric tons) of carbon move through the slow carbon cycle every year.62% divided by 100 = 0.62 x 2,000 lbs/ton = 1,240 lbs of effective lime material (ELM) so you will need more of the 62% ECCE coarse limestone to equate to 1 ton or 2,000 lbs of effective lime material. 2,000 lb ELM/ton divided by 1, 240 lb ELM/ton = 1.61 x $48/ton = $77.42. Compare this to the cost of a ton of the fine limestone (ECCE 100% ...Weathering is the deterioration of rocks, soils and minerals (as well as wood and artificial materials) through contact with water, atmospheric gases, sunlight, and biological organisms.Weathering occurs in situ (on-site, with little or no movement), and so is distinct from erosion, which involves the transport of rocks and minerals by agents such as …
