Question

Which color is used in the topographical map to show water bodies like perennial river, canal, well, tank, and spring?
A. Red
B. Yellow
C. Blue
D. Black

Answer 1

Hint: Maps drawn at relatively large scales are called Topographical maps, which are also known as general-purpose maps. Important cultural and natural features are shown by these maps such as water bodies, relief, settlements, vegetation, cultivated land, and transportation networks, etc. The National Mapping Organisation of each country prepares and publishes these maps.

Complete step-by-step solution:
The topographical maps use the color blue to show water bodies like perennial rivers, canals, well, tanks and springs. Most contour lines, which are relief elevations and features, are denoted by the colour brown on a map. The colour green is used to denote vegetation such as woods, trees, etc.
The topographical maps in India are prepared the Survey of India for the entire country. The topographical maps are drawn at different scales in the form of a series of maps. Hence, all maps employ the same projection, reference point, symbols, scale, conventional signs, and colours in a given series. The International Map Series of the World and India and Adjacent Countries Series are the two series under which the topographical maps are prepared in India.
Thus, option (C) is correct.

Note: The Survey of India prepared the topographical maps under India and Adjacent Countries Series till the coming into existence in 1937 of Delhi Survey Conference. Thereafter, the Survey of India abandoned the preparation of maps for the adjoining countries and consequently, it confined itself to prepare and publish the topographical maps for India according to the specifications laid down for the International Map Series of the World.
