(l) Abu is a popular holiday resort. Mention any three features seen in the map extract which attract holiday makers to Abu.

Answer 1

(a) The compass direction of Sunset point from the settlement of Anadra is South-East.

(b) The drainage pattern in grid square 2315 is Radial.

(c) There is a dry ‘Nadi’ flowing from Lakhawa Ka Khera and also some dry tanks in that area which show that the region has seasonal rainfall, as when the rain falls these features ‘Nadi’ and Tanks are full of water.

(d) 9.6 cm = 2.8 km.

(e) Verbal Scale is not a suitable method of representing the scale of a map as in this method we make statements such as 1 cm = 1 km or 1 inch = 5 miles, but this type of statement can not be used in different parts of the world as they require to know the units of measurement. But in the Representative Fraction this problem is not there as the unit of measurement in the numerator and denominator is same.

for example : `(1 ("Distance on map"))/(100000 ("Distance on ground"))` or 1 : 100000

It means 1 unit on the map represents 1,00,000 units on the ground, if the unit of measurement is cm then it will be 1 cm on the map = 1,000 cm on the ground. The unit of measurement can be changed or converted to any unit. Thus it has its international value and called ‘International Scale’.

(f) 
(i) Anjini Devi ka Mandir is at 229160 six figured grid.
(ii) Six figured grid of D 1327 is = 217105.

(g) The three different kinds of roads in grid square 2411 are:
(i) Metalled Road (ii) Unmetalled Road (iii) Pack track
One kind of road in grid square 2515 is ‘Foot path’.

(h) The people living in the northern region of the map extract adopt two main occupation:
(i) Cultivation: On the north western region of the map extract people adopt cultivation as their occupation because the ‘yellow wash’ in this region shows that the land.is cultivable, secondly it has lot of perennial wells which supports the cultivation in this region.
(ii) Forestry: On the north eastern region there are evidences of the forests, as it is coloured in green colour and at two places its written ‘Fairly dense mixed jungle’ and ‘Open mixed jungle’ so the forestry is the main occupation of the people in this region.

(i) In grid square 2115 the slope is gradual and gentle as the contour lines drawn in this region are far a part from each other where as in 1811 the contour lines are drawn very close to each other which means it has steep slopes.

(j) 
(i) Fire line is a clearing made in the forest to prevent the spread of forest fire as shown in grid square 2316.
(ii) The pipe line in grid square 2209, takes the water from the perennial tank Kodra reservoir shown is southern part at 220090 grid to the main town ‘Abu’.

(k) 
(i) The red square in grid square 2514 show the ‘temporary hut’.
(ii) 4r is in grid square 1612 shows the relative height of the embankment on dry or seasonal tank is 4 metres.

(l) 
(i) Mt Abu is situated on a high altitude which provides pleasant climate, some of the peaks are 1409 and 1327 metres.
(ii) There are lot of temples to see as Anjini Devi ka Mandir, Adhor Devi ka Mandir, Dilwara Temple, etc.
(iii) It also provide scenic beauty such as the whole area is covered with forests, steep slopes attract people for mountaineering, sunset point and cave dwelling etc.
