प्रश्न
Distinguish Vertical Interval and Horizontal Equivalent.
उत्तर
The difference in height between two adjacent contour lines is known as the Vertical Interval (V.I.). Whereas the distance between any two adjacent contour lines is called the Horizontal Equivalent (H.E.). The Horizontal Equivalent is calculated with the help of the scale of the map. The value of the H.E. is less when the slope is steep and more when the slope is gentle.
