Study the extract of the Survey of India Map Sheet No. 45 D/10 (Toposheet No.1) and answer the following questions (Easting 11-21, Northing 13-23): (a) Give the four figure grid reference of the settlement of Pamera. [2) (b) Give the six figure grid reference for the surveyed tree North East of Bamba settlement. [2] (c) What is the direct distance in kms between Malgaon and Gulabganj ? [2] (d) What is the difference between drainage pattern in grid square 2013 and 1422? [2] (e) Draw the conventional symbols for: (i) A tehsil boundary (ii) A temple [2] (f) What evidences on the map show that the region receives seasonal rainfall? (g) What is the main occupation of the p eople of the region in the map extract? Give reasons for [2] your answer. (h) Give a reason for each of the follow ing (i) Disappearing streams in grid square 2018. (ii) Broken ground along the banks of River Sipu. [2] (i) What is the area in square Kms of the region enclosed within Easting 13 and 18 and Northing 17 and 21? [2) (j) What is the R.F. of this map? What does it mean? [ICSE Specimen Paper, 2018) [2] Ans. (a) Pamera- 1622 (b) Samba- 195146 (c) The direct distance on the map between Malegaon and Gulabganj is 6.5 ems. Scale given 2 em = 1 km Yz x 6.5 = 3.25 kms. distance on the ground. (d) 2013- Radial, 1422- Dendritic. (e) (i) A tehsil boundary (ii) A temple ~ (Red in colour) (f) The evidences are the presence of broken ground, and seasonal streams. (g) The main occupation is agriculture. The presence of lined perennial well and yellow cultivable land gives evidence. (h) (i) It is because of scanty rainfall and high temperature due to which water is evaporated. In sandy porous ground disappeared water. (ii) Due to soil erosion when flood occurs during monsoon. (i) Basting 13 and 18 = 5 grids Northing 17 and 21= 4 grids Each grid is of 1 sq.km. Therefore, 5x4=20 km2 (j) is missing Q.2. Study the extract of the Survey of India Map sh eet No. 45D/7 and answer the following questions : (a) Give the six figure grid reference for : (i) A268 (ii) Temple south east of Khara [2] (b) Nam e the following : (i) The drainage pattern seen in 9185. (ii) The pattern of settlement seen in 9787. [2) (c) What do the following symbols m ean ? (i) 3r in 9089. (ii) 200 in 9383. [2] (d) Name two types of vegetation found in the region east of easting 93. [2] (e) Give two evidences which suggest that the rainfall received in the region shown on the map extract is seasonal. [2] (f) Calculate the area of the region between 85-90 northing and 90- 95 easting. Give your answer in kilometer. [2] (g) Mention any two man made features and two natural features in grid square 9080. [2] (h) What is the direct distance in kilometers between the surveyed tree west of Rampura (9580) to the chhatri in Juvol (9282)? [2] (i) Mention : (i) The most commonly used means of transport in the area shown on the map extract. (ii) The main occupation of the people of the region in the south eastern part of the map extract. [2] (j) (i) What is the compass direction of Rampura (9580) from Karja (9781)? (ii) Identify the landform marked by contours in 9782. [2] [ICSE, 2018) s. (a) (i) 950834 (ii) %3861 (b) (i) Radial pattern of drainage. (ii) Dispersed settlement. (c) (i) Dry tank with embankment of 3 meter relative height. (ii) Contour height from sea level. (d) Dense mixed jungle and dense jungle. (e) Seasonal rainfall is experienced in the map extract: (i) Seasonal streams (ii) Broken ground (f) Scale 1:50 000 - therefore 1 em on the map represents 50,000 em on ground 85-90 = 5 90 - 95 = 5 5 X 5 = 25kfi2 (g) Man-made feature: Permanent settlement and perennial wells. Natura] feature- seasonal river and broken ground. (h) 3.5 kilometres. (i) (i) Cart-track (ii) Agriculture (j) (i) South-west (ii) Escarpment. [ICSE Marking Scheme, 2018] ---~--
