Answer 1

(a)
(i) The six-figure grid reference of ∆ 364 is 957744.
(ii) The six-figure grid reference of the temple at Rampura is 954806.

(b)
The two features which show that the region has seasonal rainfall are:
(i) Dry river with water channel shown in the northern part of the map extract.
(ii) Dry tanks shown in the southern region of the map extract.
The above two features show that they have water in them during the rainy season.

(c) The distance between Juvol and Amiwada is = 5 cm = 2 1/2 km (or 2 km and 500 metres) = 2 km 500 metres (as per scale of the map).

(d)
(i) The chief form of irrigation shown in the map extract is perennial lined wells.
(ii) There is a clear evidence of this type of irrigation shown in the north-west corner of the map extracted around the Juvol and Chekhla villages, which are situated on a cultivable land and the perennial lined wells found in that area are the only source of the irrigation.

(e) The streams in grid square 9478 do not join the main river as these are “disappearing” streams, they do not have enough water to reach the main river and dry up in the sand. Similar type of streams are found in the grid square 9575 also.

(f)
(i) These are disappearing streams, which are generally shown with black broken lines..
(ii) Black curved lines show the broken ground.

(g) The landforms shown by the contours in grid square 9876 are:
(i) A conical hill with spot height 381.
(ii) The southern part of this hill is a ‘spur’.

(h)
(i) Balram Nadi is flowing from South-East to North-West.
(ii) Balram Nadi joins the main river on its left bank.

(i) (i) The main occupation of the people living in the area shown in the map extract is agriculture.
(ii) ‘Most of the area has ‘yellow wash’ which indicates cultivated land.

(j) 
(i) The scale is defined as the ratio between the distance of any two points on the map with the actual distance of the same points on the ground.
(ii) The scale of the map extract provided, is 2 cm = 1 km. which means 2 cm on the map is equal to 1 km on the ground.
