Answer 1

1. 1. 6913
   2. 674190
2. 1. The number of grid squares enclosed between Eastings 66 and 71 and Northings 15 and 19 is 20. As each grid square represents an area of 1 km × 1 km, or 1 sq. km, the total area covered by these 20 grid squares is 20 sq. km.
   2. Hanumanji ka Mandir is located to the north-east of Gautam Maharishi Mandir.
3. 1. ‘Falls 15m’ in grid square 6718 shows a waterfall with a height of 15 metres. Such falls are formed in hilly regions where a river makes a sudden and nearly vertical drop along its course.
   2. The distance measured on the map is 3.2 cm. As the scale is 2 cm = 1 km, the real distance comes out to be 1.6 km.
4. 1. Abu is a hilly region that receives its water from seasonal streams, wells, and artificial lakes. This is because:
      (A) There are no perennial rivers; only seasonal streams are found in the area. (B) Perennial lined wells and Nakhi Talao are present, as shown by the blue conventional symbols on the map.
   2. The large number of closely spaced contours shows that the land has a steep slope.
5. 1. The broken black lines in grid square 6221 represent broken ground. Such features are commonly found in arid or semi-arid areas, especially along the banks of seasonal rivers or streams. This occurs because the soil is soft and sandy, and it cracks and breaks easily due to alternating wet and dry periods.
   2. Except for Abu, there are no other settlements shown in the given map extract, as most of the region is covered with forests and rocky knobs, and there is a lack of perennial streams, transport facilities, and employment opportunities.
