Question

Which colours are used in Contour maps?
A) Brown
B) Blue
C) Green
D) All of the above

Answer 1

Hint: Contours are imaginary lines that connect points with similar elevations above sea level.A contour map, such as a topographic map, is a map with contour lines that display valleys and hills, as well as the steepness or gentleness of slopes. In steep terrains, contour maps are frequently used on actual maps to depict altitude.

Complete answer:
Colours are used to signify physical, economic, and cultural characteristics. It would be impossible to comprehend the contour map without the use of colour.
Let us look at the given options.
A)Most contour lines on a map, which are relief features and elevations, are coloured brown. Contour lines, which are commonly curved, parallel brown lines, connect locations of equal elevation to indicate the form and elevation of the ground. Thus, option A is correct.
B)The water (blue) is frequently one of the first features visible on a topographic map. Lakes, bogs, rivers, and drainage are all represented by the colour blue. Thus, option B is correct.
C)The topographical map uses the colour green to depict agricultural fields. Green is used on most topographic maps to represent vegetation, national parks, and animal control zones. Thus, option C is also correct.
D)Since options A, B, and C are right, this is the correct answer. Therefore ‘All of the above’ is the correct answer.

Thus the correct answer is option ‘D’.

Note: Different colours may be used to depict area features on topographic maps. They'll also use the red colour to denote places of strategic importance. Boundaries are depicted in black colour, with various sorts of dashes and/or dots used to indicate the type of boundary: international, state, county, or other governments.
