Document Summary
Module 2: the shaking earth - earthquakes the shaking. Earth - earthquakes: describe the global distribution of earthquakes and how often quakes of various magnitudes occur. The earthquakes occur at the boundaries between earth"s tectonic plates: majority of recorded earthquakes have occurred on edges where continents meet oceans. Fault: a region where rocks have broken over some area, the fracture plane in the earth where the two sides move relative to each other, source of earthquakes. Dip-slip faults: vertical motion along slanting plane: normal fault: side leaning on its neighbour drops down (as gravity would suggest) divergent boundaries, reverse fault: side being leaned on drops down convergent boundaries. Strike-slip faults: horizontal motion transform boundaries (largest quakes. Oblique faults: combination of horizontal and vertical motion (not studied in. Type 1 & 2 produced here) great detail: describe how the earth builds, stores, and releases energy in earthquakes (elastic rebound) Stores: mexico ex seismic energy can be trapped in soft sediments.
