EESA06H3 Chapter Notes - Chapter 3: Oceanic Crust, Submarine Volcano, Transform Fault
Document Summary
Continental drift: wegener argued that the continents were once joined together but later drifted apart. They had not seen the southern hemisphere data. Wegener could not explain why or how the continents moved. Most earthquakes occur in discrete belts, like the one that runs along the western coasts of. Most earthquakes in the oceans occur along the winding crests of mid-ocean ridges. Few earthquakes occur in large areas of the seafloor. More earthquakes occur on narrow continental shelves compared to wider ones. Many earthquakes occur in ocean trenches and associated island arcs. Commonly occur in belts, like the one extending along the western coasts of north and south. Some occur in the centers of oceans, like the ones near iceland. Some form in the middle of continents. Earthquake & volcanic activity and the earth"s lithosphere. Earthquakes, volcanoes, and other processes that deform the crust and mantle are called tectonic activity or simply tectonics.
