Question

What is a contour interval

Answer 1

Answer:

Vertical distance between contours is called contour interval

Explanation:

Contour lines are lines that connects point of equal height. The vertical distance or the difference in elevation between two contour lines is known as contour interval. For example  a set of 100 contours is used to represent a hill of height 500 ft. So, the vertical distance between each  contour will $\frac{500}{100}$feet

$= 5$ft contour interval.

Answer 2

A line drawn on a topographic map to indicate ground elevation or depression. If the contour intervals are closer together, the steeper the elevation.
