What is a 'contour'?
Solution 1
Contours are imaginary lines joining places having the same elevation above mean sea level. In other words, these are imaginary lines joining all the points of equal elevation or altitude above mean sea level. They are also called “level lines”. A map showing the landform of an area by contours is called a contour map. The method of showing relief features through contour is very useful and versatile. The contour lines on a map provide a useful insight into the topography of an area.
