How to calculate contour intervals?
Understand the Problem
The question is asking for the method or steps required to determine the contour intervals on a topographic map. This involves understanding elevation differences between contour lines and might also require specific measurements or calculations based on the scale of the map.
Answer
Vertical distance between contour lines on a topographic map.
The final answer is the vertical distance between contour lines, calculated by dividing the elevation difference of two index contours by the number of intervals between them.
Answer for screen readers
The final answer is the vertical distance between contour lines, calculated by dividing the elevation difference of two index contours by the number of intervals between them.
More Information
Contour intervals help in understanding the topography of an area by showing the rise and fall in elevation across a terrain.
Tips
A common mistake is not correctly identifying the index contour lines, which leads to incorrect calculations.
