GEOL 140 Study Guide - Midterm Guide: Continental Crust, Oceanic Crust, Geophysical Global Cooling
Document Summary
Questions hypothesis experiment results . 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) The sliding down of a mass of earth or rock from a mountain or cliff. What variables/conditions make landslides more likely: water (rainfall, groundwater) Slope (steeper slopes less stable; natural or manmade slopes) Lack of vegetation (from clearcutting, fire, or previous erosion) Triggered by consecutive storms with rainfall to those of. Had about four times as much rainfall as usual, especially in higher elevations. Exfoliation fractures & groundwater seepage contributed as well. Convection: circulation of rising (hot, low density) material and sinking (cooler, denser) material. Convecting mantle pushes/pulls on rigid crust: crust breaks into tectonic plates. Tectonic plates constantly moving and reshaping (due to.
