Question 1: Describe the difference between physical and chemical weathering. Describe the four main types of chemical weathering, give an example of each, and state if each is an example of congruent or incongruent dissolution.
Question 2: Explain why kinetic factors are often more influential in determining soil mineralogy than thermodynamic factors, citing an example.
Question 3: Provide two chemical equations that depict the oxidation of pyrite in acid mine (or rock) drainage systems (include one involving ferric iron as reactant). In what way is this reaction different than most other mineral dissolution reactions in natural systems?
