TYPES OF CONTOUR A. INDEX CONTOUR - Every FIFTH CONTOUR LINES is an (INCHES LINES) and is indicated by HEAVIER BROWN LINE. B. INTERMEDIATE CONTOUR - Are the (FOUR LIGHTER CONTOUR LINES) drawn between the (INDEX CONTOURS) C. SUPPLEMENTARY CONTOUR - Represents (HALF INTERVALS) between (INTERMEDIATE CONTOURS) and is shown by (BROWN LINES) D. DEPRESSION CONTOUR - an AREA THAT IS LOWER IN ELEVATION that all the surroundings terrain is indicated (TICK MARKS POINTING DOWN A SLOPE) E. APPROXIMATE CONTOUR - BROKEN LINES (of the same thickness and type as the contour replayed) CONTOUR LINES TO IDENTIFY GROUND FORMS. A. HILLS - SERIES OF CONCENTRIC CONTOUR LINES which (GRADUALLY GROW SMALLER, ENDING WITH A SMALL CLOSED CONTOUR LINE IN THE CENTER) B. PEAKS OF HILL TOPS - SMALL CLOSED, RELATIVELY CIRCULAR CONTOUR at the CENTER OF THE SERIES OF CONCENTRIC CONTOUR LINE. C. RIDGES - SERIES OF CONNECTING PEAK OR A VALLEY FLOOR D. SADDLE - LOW POINT BETWEEN TWO PEAKS (along the crest of a ridges) E. SPUR - That form a (SERIES OF SUCCESSIVE ROUNDED U SHAPES) F. CLIFF - LINES THAT FORM A SERIES OF SUCCESSIVE V-SHAPE - STREAM COURSE THAT NEITHER HAS NOR DEVELOPED A VALLEY FLOOR
Understand the Problem
The question appears to be a detailed description of different types of contour lines and their characteristics used in topographic mapping. It outlines various categories of contour lines and their specific features or definitions. The purpose is to educate on how to identify different ground forms based on contour lines.
Answer
Index, intermediate, supplementary, depression, and approximate contours.
Types of contour lines include index contour, intermediate contour, supplementary contour, depression contour, approximate contour, each serving different functions in depicting elevation changes on topographic maps.
Answer for screen readers
Types of contour lines include index contour, intermediate contour, supplementary contour, depression contour, approximate contour, each serving different functions in depicting elevation changes on topographic maps.
More Information
Contour lines graphically represent the elevation and shape of the terrain on topographic maps, showing vertical dimensions across horizontal regions. Each type of contour line helps understand different levels and characteristics of the landform.
Tips
A common mistake is failing to recognize different line types, which could mislead interpretations of topographic features. Remember that elevation is indicated only on index contours.
