Contour

Explanation:

• The brown line in grid square 1516 called Contour in the year 2005 topo​sheet.
• Contour lines are the imaginary lines drawn on a toposheet to mark the places on an equal level to the mean sea level.
• They mark the points of equal elevation.
• That is why they are also known as "level lines".
• The height and slope or  gradient of the landform can be predicted using the contour lines on a contour map.
• The distance between the contour lines determines the slope. If they are closely packed then the slope is steep but if they are far apart then the slope is gentle.
