If the contour interval of a map is doubled, how many contour lines are needed to show the same increase in elevation? a. half as many

b. twice as many

c. the same number

The answer is "Option a"

Explanation:

The vertical distance or height gap between both the contour maps is now a contour interval. Its indexed outlines from each of the fifth contour maps appear clear. The height of its terrain will also increase unless the number associated with specific contour lines are increasing unless the outline interval is increased, half the number of outline lines are needed to indicate the same elevation rise.
