GEOL 140 Final: Study Guide
Document Summary
Steps of the scientific method: questions hypothesis experiment . Dependent variables variables we observe/measure (they depend on the treatment) Control group group where no effect is expected. Controlled variables independent variables kept exactly the same among all treatments. Be able to interpret graphs of experimental results. Be able to plan an imaginary experiment (or parts of it) Landslide/mass wasting: the sliding down of a mass of earth or rock from a mountain or cliff. Slope steeper slopes less stable; natural or manmade slopes. Lack of vegetation from clearcutting, fire, or previous erosion. Triggered by consecutive storms with rainfall similar to those of hurricanes francis and ivan. Had about four times as much rainfall as usual, especially in higher elevations. Exfoliation fractures & groundwater seepage contributed as well. It"s super important people should know if they"re in danger. Pros safety, people knowing where landslide hazards are. Cons expensive, will take a long time. Origin of earth melty ball of magma.
