The lines that are drawn on a map or a globe to show the heights of specific areas are called contour lines. Contour lines represent the elevation of an area above sea level. These lines connect points of equal height, allowing us to visualize the shape and steepness of the terrain on a map. Contour lines closer together denote steeper slopes, while contour lines that are further apart represent gentler terrain. By analyzing the contour lines, it is possible to understand the topography and relief of an area.
