Determine the contour interval for the map 2. find the known elevation closest (o the point. This may be a benchmark or acontour line. Remember that every fifth contour line is a heavier index contour, but you may have to follow contour lines some distance before finding an elevation label 3. Determine whether the point is higher or lower than the known elevation by examining the sequence of adjacent contour line elevations and by taking note of nearby feature names, such as "fire tower," “valley” and so forth, 4. Estimate the distance between the point and the contour lines that bracket it to get the elevation Using this procedure and what you have learned in the text, answer the following questions (a) In Figure 9.18, how high is the highest point on the rim of the crater? Explain how you made this estimation. 4 [ ey 13 0ok 350 ihe ¢ (b) In Figure 9.18, what is the elevation of the lowest paint of the crater?

The map below shows surveyed elevations for a coastal area Using these elevation data, construct a topographic map on the figure that shows the topography of the area, using, 3 contour interval of 20 feet. One line has been done to get you started Remember that contour lines must follow the rules you have just learned, including the guideline that contour lines donft go straight across streams— thelines must form a v oriented correctlyto indicate the direction of streamflow Points at elevations of 20, 40, 60, and 80 feet wil ie on contour lines and help you locate the lines. You will have to estimate where those contour ines pass between the other elevation points. (A contour hine vll be neares 10 point whose value is close to that of the contour fine, and farther away from apoint whose value Is farther from that of the contour line ) R Shesa— | ey Rules for Reading Contour Lines on Topographic Maps Section: Date: Complete the following sentences to summarize what you've learned about contour lines exmS o citlerent >leyancn (a) Two different contour lnes cannot cross because ALY YTPY (b) The spacing between contour lines on a map reveals thi S the ground surface.
