Imaginary lines showing the height of land above sea level.

Lines indicating depth of water bodies.

Symbols showing population density.

Contours are imaginary lines that connect locations that have the same elevation above mean sea level. In other words, these are imaginary lines that connect all points of equal elevation or altitude above mean sea level. They are also known as "level lines." A contour map is a map that depicts the landform of a region using contours. The method of displaying relief features through contour is extremely useful and versatile. The contour lines on a map offer valuable information about an area's topography.

Study the contour pattern and answer the following questions. Name the type of slope between A and B ; C and D and E and F .

A and B Gentle Slope C and D Steep Slope E and F Gentle Slope If the contours are widely spaced it represents gentle slope and if the contours are closely spaced it represents a steep slope. In the above representations of contours, Between A and B, and E and F there are closed contour lines and between C and D there are widely spaced contour lines.

Study the contour pattern and answer the following questions. Find out the direction of E , D and F from G .

From G, E is in the west, D is in the North, and F is in the South directions. The knowledge of directions is must to understand any geographical construction. It helps in identify the actual position of that structure on the Earth.

Study the contour pattern and answer the question follows: Name the geographical feature formed by contours.

Plateau is the geographical feature formed by contours. In the topography of the plateau, the edge-contour lines are drawn close by while the intermediate portion is almost devoid of contour lines. Here in the picture one side contour lines are closed which shows comparatively high slope. A plateau is a large area of high and fairly flat land. It rises from a few hundred meters to a few thousand meters from sea level.
