___ 4) Points A and B are reference points on the topographic map below. The symbols show the highest elevations on

Eagle Hill and Timony Hill. Elevations are shown in feet.

State a possible elevation of the top of Patriot Hill in the given topographical map.

___ 5) The passage describes the New Madrid fault system. The numbers on the map show the predicted relative damage atvarious locations if a large earthquake occurs along the New Madrid fault system. The higher the number, the greater therelative damage.

THE NEW MADRID FAULT SYSTEM:The greatest earthquake risk area east of the Rocky Mountains is along the New Madrid fault system. The New

Madrid fault system consists of a series of faults along a weak zone in the continental crust in the midwestern UnitedStates. Earthquakes occur in the Midwest less often than in California, but when they do happen, the damage is spreadover a wider area due to the underlying bedrock.

In 1811 and 1812, the New Madrid fault system experienced three major earthquakes. Large land areas sank, newlakes formed, the course of the Mississippi River changed, and 150,000 acres of forests were destroyed.

(a) On the map below, draw the 4, 6, and 8 isolines indicating relative damage.

(b) Using the predicted damage numbers plotted in part (a), place an X on the map to indicate where the New Madridfault system mentioned in the reading passage most likely exists.
