Question

interpreting contour lines
use the drop - down menus to answer the questions about the topographic map.
what is the elevation at point a?
what is the elevation at point b?
what is the relief between points a and b?

Explanation:

Step1: Identify elevation of Point A

Point A lies on the 750 contour line, so its elevation is 750 units.

Step2: Identify elevation of Point B

Point B lies on the 700 contour line, so its elevation is 700 units.

Step3: Calculate relief between A and B

Relief = Elevation of A - Elevation of B
$\text{Relief} = 750 - 700$

Answer:

What is the elevation at point A? 750
What is the elevation at point B? 700
What is the relief between points A and B? 50
