Notes:
Besides having an affect on the physical location of the continents, plate tectonics accounts for the major geological features of our planet. This map shows some of the phenomena associated with subduction zones: volcanoes, earthquakes, and deep ocean trenches. The extremely hot temperatures of the inner earth causes super heated water and gasses from the subducting plate to rise, leading to a chain of chemical reactions that melts the mantle above the subducting plate. This melted rock is magma.
