GEOLOGY

Detailed explanation-1: -Contour lines are lines drawn on a topographic map connecting points of equal elevation. They are also called “level-lines”. Contour lines are useful because they depict the shape of land used by countless professions-foresters, hunters, miners, engineers etc.

Detailed explanation-2: -Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level. Contours make it possible to show the height and shape of mountains, the depths of the ocean bottom, and the steepness of slopes.

Detailed explanation-3: -A contour line is a line drawn on a topographic map to indicate ground elevation or depression. A contour interval is the vertical distance or difference in elevation between contour lines.

Detailed explanation-4: -Contour lines are lines drawn on a map connecting points of equal elevation, meaning if you physically followed a contour line, elevation would remain constant. Contour lines show elevation and the shape of the terrain. They’re useful because they illustrate the shape of the land surface-its topography-on the map.

Detailed explanation-5: -Contour lines are Imaginary lines joining places that have the same height above the sea level. And the method of representing the height on the map by using contour lines is called Contouring.
