Draw a cross-section of an oceanic-continental convergent plate boundary. Show the directions of
  relative plate motion. Put stars for the locations of earthquakes. Put triangles with smoke out the top
  for the locations of volcanoes. Label the trench and subduction complex. What will be an ideal response?

Plate tectonics explains, at least to some extent, all of the following phenomena: the distribution of
earthquakes and volcanoes, the locations of ore deposits and mountain systems, climate and ocean
circulation patterns, and the geographic distribution, evolution and extinction of life forms.
