On a topographic map how would you show an island in the ocean with an elevation of 80 feet if the contour interval is 10 feet?

Answer 1

You would just add 10 every contour line you pass until you get to the number 80.

Answer 2

To show an island with an elevation of 80 feet on a topographic map with a contour interval of 10 feet, you would draw a closed contour line at the 80-foot elevation. This contour line would encircle the entire island. Additionally, you would draw contour lines at intervals of 10 feet above and below the 80-foot contour line to represent the varying elevations of the island. The contour lines closer together indicate steeper terrain, while contour lines farther apart indicate flatter terrain.

Answer 3

You would draw a closed contour line at 80 feet above sea level, and then use multiple contour lines at intervals of 10 feet below that (70, 60, 50, etc.) to show the slope and shape of the island. The contour lines would get closer together as the terrain becomes steeper.

Answer 4
