Contours show the elevation above sea level. The steeper the slope the closer the contour lines. Therefore, on a low elevation the contours will be far apart.
In areas with low relief, the contour interval on a map will typically be smaller. This is because the elevation changes are gradual and subtle, so more contour lines are needed to accurately depict the gentle slopes and terrain features. Smaller contour intervals help to provide a more detailed representation of the topography in areas with low relief.
The Relationship between the relief of an area and the contour interval on a map of the area is A contour line
Contour line connect points of equal elevation on a map, whereas relief is the difference in elevation from the highest and lowest on a map.

Contour lines are lines on a map that connect points of equal elevation, indicating the shape and steepness of the terrain. Relief, on the other hand, refers to the variation in elevation and the physical features of the landscape, encompassing both the high and low areas. Together, contour lines provide a detailed representation of the relief by illustrating how elevation changes across the map, helping users visualize the topography of the area.

To calculate the total relief on a topographic map, subtract the elevation of the lowest contour line from the elevation of the highest contour line within the map area. This difference represents the total vertical distance between the highest and lowest points on the map.
Choropleth map
Relief on a topographic map is shown using contour lines, which represent different elevations. The closer together the contour lines are, the steeper the terrain, while farther apart lines indicate flatter areas. Relief can also be depicted using shading or hill shading to show the three-dimensional nature of the landscape.
