Answer 1

Hint:The word topography has been derived from two Greek words topos' and 'grapho' which means a place' and to draw or depict, respectively.

Complete answer:
However, it is different from a physical map as it uses contour lines to show changes in the landscape. All topographical maps show two types of features:
(a) Physical features: These include valleys, hills, plateaus, peaks, passes, waterfalls, etc. They are depicted by 'Contours' i.e., the lines that join places having the same height above mean sea level. By noticing the pattern and density of the contour lines we can determine the shape, height and gradient of a particular area with its specific features.
(b) Cultural or Man-made Features: These include roads, railways, bridges, buildings, canals, etc. They are represented by symbols called Conventional Signs.
 The map has three dominant colours. These are green, yellow and white. The green area contains vegetation, chiefly forests. Note the type of forests indicated on the map. There are three types of forests-dense jungle, dense mixed jungle and fairly dense jungle. All the area covered in yellow is cultivated land. The white portion is barren land. No crops are grown in this land. Part of it is also open scrub. Most of the hilly terrain is also.There is a patch of white. It indicates that the forest has been cut and deforestation has taken place.

Hence, the correct answer is option (B).

Note:In India, Ordnance maps are published by the 'Survey of India Department', Dehradun.A topographic map is similar to a physical map in the sense that it shows different physical landscape features.
