Read the para ‘Contour Lines’ and comment on it. Contour Lines A contour is a line joining the places with equal heights. On the map of Nimpur you would have seen that there is a line passing through the village, this is the 50-meter contour line. All places on this line will have the same height of 50 meters. Contour lines will be in irregular shape depending upon the landform. These cannot cut with each other. The distance between two contour lines will depend upon the landscape. If the land has a steep climb then the contour lines will be near to each other. If the slope of the land is gentle, then the contour lines will be quite far from each other.

Answer» A contour line of a function of two variables is a curve along which the function has a constant value. In cartography, a contour line joins points of equal elevation above a given level, such as mean sea level. Contour lines are curved, straight or a mixture of both lines on a map describing the intersection of a real surface with one or more horizontal plains.
