Question

What is a contour interval

Answer 1

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

Answer 2

Vertical distance between contours is called contour interval

Step-by-step 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
`(500)/(100) \\`feet

`= 5`ft contour interval.
