some factors that help explain differences in density that you observe in these
rocks.
w Sketch a diagram illustrating
the internal structure of the earth as defined by density of its layers.

Using maps in the classroom, the world map you printed, and
the 14 sites you plotted, make a list giving the topography and geographic
setting of each site. (Keep this list handy for future use!)
