mass writing multiple choice question

1. What type of mass movement event would most likely occur in Yosemite National Park, or any other place with exceptionally steep cliffs of solid bedrock?A. rock slumpB. debris flowC. rock fallD. earth creep    2. Go to http://seismo.berkeley.edu/blog/seismoblog.php/1996/12/10/199. In 1996 Yosemite NP experienced a fatal mass movement event. What knocked over the trees between the base of the cliff and Happy Isles Visitor Center during this event?Select one:a massive rockb. the wind blast from a massive rockc. seismic shaking3. Which best describes what causes mass movements of land? Select one:a. Friction between debris and bedrock causes debris to move downslope.b. Movement occurs when force of gravity exceeds resisting strength.c. Mass movement is caused when materials are on inclined slopes.d. The more cohesive the materials, the more likely they are to move.4. Which factor, when present, generally increases slope stability (that is, makes them less likely to fail)?Select one:a. weatheringb. faults and fracturesc. large amount of waterd. vegetation5. How is the mass movement phenomena classified when the slope failure occurs along a spoon-shaped, curved sliding surface?Select one:a. creepb. debris flowc. slumpd. rock slide6. What would make a hill slope less stable?Select one:a. Bedding planes perpendicular to the slopeb. Bedding planes parallel to the slopec. Foliation perpendicular to the sloped. Shallow slope angle7.

From what you have learned in lecture, what type of mass wasting event is seen in this video?Select one:a. mudslideb. rock slidec. soil creepd. debris flow8. Which one of these is not a factor contributing to landslide or rockfall hazards.Select one:a. The material strengthb. The orientation of bedding planes, foliation, and joints.c. None of the aboved.

Which events could increase the chance or trigger slope failure (landslide)?Select one:a. increase in steepness due to stream or waves under-cutting or development (road-cut)b. addition of weight or water to the slope through development or irrigationc. a wet stormd. wildfire or logging destroying vegetatione. all of the these
