Document Summary

What is good about volcanoes: builds up land (makes continents, they are beautiful (tourism, geothermal energy, good soil for agriculture, generate ore deposits. E. g. copper; gold; diamonds (in kimberlites: atmosphere + hydrosphere effect. Co2 producer (saved us from snowball earth ) The downslope movement of solid earth materials under just the influence of gravity. Earthquakes and volcanoes predominantly at plate tectonic boundaries. Everywhere you look there are slopes where landslides can happen (1) understand the hazard (in general) What determines whether a landslide occurs or not: slope steepness, nature of the material, soil/aggregates (loose stuff and debris, solid rock/ice. How much internal strength: triggering effects e. g. , rain on a slope; earthquakes; human action; etc. Leads to a wide variety of down-slope movements let"s look at a classification chart. Based on: mechanism (flow, slip, and fall, velocity (low to high) Rock or debris: soil- fluction saturated debris) avalanche. Fall: earthflow debris, earthflow with slump (rotational)
