Document Summary
More chemistry of co2: most co2 ends up at calcium carbonate, all of the first 4 must be satisfied simultaneously, as the partial pressure of co2 rises, ph falls, equation 5 is important in volcanoes and cement manufacture. More chem of co2: delta h is negative, warming the ocean releases a lot of co2. It is the chemical decay and physical fragmentation , under conditions on the earth"s surface, of minerals that formed for the most part at high temperatures and pressures in the interior of the. Earth: a highly simplified example, these minerals are usually the product of volcanic eruption and silicate-rich rocks. Single-celled protists with shells: 100 micrometers - 20 centimeters long. Surface rock crushed under ice: weathering, this exposes sulfide minerals which then get oxidized. Sulfuric acid reacts with h2so4 which then creates co2 which then goes back into atmosphere.
