locations of plate boundaries represented with lines. Note the legend; each type of boundary is
represented by a different line color:
Consider three pairs of cities: (1) Palm Springs and Yucca Valley, California, USA; (2) Mecca, Saudi
Arabia, and Port Sudan, Sudan; and (3) Lahore, Pakistan and Leh, India. For each pair of cities, are
the cities moving towards each other, away from each other, or parallel to each other? How do you
know?
(Hint: Search for each pair of cities in Google Earth and look at their locations relative to the nearest
plate boundary. The first pair of cities is shown below. The plate boundary is represented by the blue
line.)
