Illegible answers are wrong. (1 point each)0T 1. Buffer solutions are at equilibrium.1T 2. The following reaction is temperature dependent.1F 3. There is more carbon dioxide in the atmosphere than is dissolved in the ocean. 0T 4. The effects of acid rain are worst in headwater streams and high-altitude lakes.2F 5. The discussion of carbonate equilibrium is made easier by the lack of kineticproblems. Equilibrium is usually maintained in the oceans, and equilibriumthermodynamic calculations provide excellent agreement with observed values. 2F 6. Soil water occupies the phreactic zone, where it fills all available pore space, and isnot in contact with gas. 0T 7. The effectiveness of biological activity in regulating the flux of elements in a givenarea is often seasonal. 2T 8. Carbonate mineral weathering is usually congruent dissolution by acid. 0T 9. One result of mineral breakdown is a release of essential nutrients in soluble formsusable by plants.3F 10. Expressed on a parts per million basis, the range of dissolved load in rivers variesover a much wider range than that of suspended load.4F 11. Suspended load almost always exceeds dissolved load (on a ppm basis) by a widemargin.1F 12. Rivers that carry the highest suspended loads are always very large rivers.
