UPSC 2015 CDS I GK Paper

The contours of an area given in the question indicate several relief features. The Conical hill is the relief feature which is not depicted here. In Cartography, a contour line (often just called a ‘contour’) joins the points of equal elevation (height) from the mean sea level. A conical hill should be shown with the help of equally spaced almost concentric contours, which is not the case here. Widely spaced contour indicates flat surface. Closely spaced contour indicates steep slope ground. Equally spaced contour indicates uniform slope. Irregular contours indicate uneven surface.
