Question

A series of closely spaced contour lines represents a :

• A. Steep slope
• B. Uniform slope
• C. Plane slope
• D. Gentle slope

Answer 1

The correct option is A Steep slope

A series of closely spaced contour lines represent a steep slope.

Note: A contour may be defined as an imaginary line passing through points of equal elevation on the earth's surface.

Characteristics of contour lines

All the points of a contour line have the same elevation.

Two contour lines do not intersect each other except in the cases of an overhanging cliff or a cave penetrating the hillside.

Equally spaced contours represent a uniform slope and contours that are well apart represent a gentle slope.

Closely spaced contours represent sleep slope.

A set of close contours with a higher figure inside and lower figure outside indicate a hillock, whereas in the case of depressions and lakes etc, the lower figures are inside and the figures are outside.





Irregular contours represent an uneven ground surface.

The direction of the steepest slope is along with the shortest distance between the contours.
