10. Vegetation is often used to stabilize slopes and prevent mass wasting - the primary reason is: (A) it deflects rainfall which might destabilize the slope (B) the roots can hold the slope together (C) it decreases the rate of soil weathering by absorbing moisture (D) none of the above-adding vegetation adds weight, making the slope more unstable 11. Abrupt and catastrophic slope failure commonly occurs because of all the following except: (A) increased load due to buildings, water etc. (B) steepening of the slope beyond the angle of repose (C) orientation of weak "failure surfaces" downslope (D) seasonal freeze-thaw cycles 12. Most mass wasting events are typically called by laypersons "landslides" which of the following is actually the correct description of a landslide? (A) Rapid downslope movement of rock or debris down a non vertical slope. (B) Rapid downslope movement of water saturated slurry of fine sediment (C) Massive slippage of a coherent block of rock or regolith. (D) Vertical collapse of rock or regolith. 13. During metamorphism, which of the following properties does not change between the protolith and the metamorphic rock? (A) mineral assemblage; (C) grain size and arrangement; (B) bulk chemical composition; (D) all of these properties may change. 14. Which is not a characteristic of dynamic metamorphism (within fault zones)? (A) exceptional heating; (B) grain deformation; (C) alignment of crystals; (D) localized evidence of high shear stress. 15. Which of the following metamorphic rocks would be found at the core of a mountain belt that formed during a continental collision, where the rocks were subjected to the highest temperatures and greatest pressures? (A) slate, (C) gneiss, (B) garnet-rich biotite schist, (D) welded tuff.
