Document Summary
Volcanic eruption, negative feedback loop, constantly monitoring volcanoes for safety, sulfur emissions from volcanoes are good for cooling effect, pollutants a. i. ii. iii. Both of these are associated with acid deposition, associated with things such as acid rain, acid snow, etc: we see a dramatic drop in ph of surface water over time with acid deposition ecosystem does, why does soil ecosystem soil not drop that rapidly, whereas the aquatic i. ii. Strong bases: sodium, potassium, calcium, ammonium hydroxide: neutralize strong acid reactions as the hydroxyl combines with the proton to produce water, oh + h+ > h2o e. i. ii. iii. iv. Dolomite mgca(co3) < magnesium carbonate: dolomite is much more resistant from acid deposition than calcite, gargoyles here are made out of dolomitic limestone, that is why it still looks good, agronomic standpoint: excess magnesium as a macronutrient is when dolomite is used v.
