Step $5$: Add the CI to the starting value and repeat the steps for the next contour line. For example, if the

starting elevation you selected was $100$ ft $,$ and the CI is equal to $20$ ft $,$ the next contour line would be

$120$ ft $.$ Continue until you reach the highest possible value on the map.

Activity $5$: Complete the following contour maps.

Map $1$: Start at elevation $)=(5ft$
