Solutions

Question 1.

(a) Classify maps showing the following areas into small scale or large scale

(1) Building, (2) School, (3) Country of India, (4) Church, (5) Mall, (6) World Map (7) Garden, (8) Dispensary, (9) Maharashtra State, (10) The north sky at night

Answer :

The classification of maps showing the given areas is as follows :

  • Small scale maps : (1) Country of India (2) World map (3) Maharashtra state (4) The north sky at night.
  • Large scale maps : (1) Building (2) School (3) Church (4) Mall (5) Garden (6) Dispensary.

(b) There are two maps with respective scales of 1cm = 100m and 1cm = 100 km. Give a well reasoned answer as to which of then would be a large scale map and which a small scale map. Recognize the type of maps.

Answer :

Out of the two maps with respective scales of 1 cm = 100 m and 1 cm =

100 km, a map with respective scale of 1 cm = 100 m would be a large scale map.

Reasons :

  • 1 metre is equal to 100 centimetres and 100 metre is equal to 10000 centimetres.
  • Thus, the value of the given verbal scale (1cm = 100 m) is 1 : 10000 in numerical terms (scale).
  • A map having a numerical scale of 1 : 10,000 or less than it is called large scale map. Therefore, 1cm = 100 m would be a large scale map.

Types of maps :

  • Maps of villages, church, agricultural fields, etc. are the large scale maps.
  • Maps of state, country, continent, world, etc. are the small scale maps.

Question 2. Using a map of India from the atlas measure straight line distance between the following cities and complete the table below.

Cities Distance on map Actual Distance
Mumbai to Bengaluru ............. ----km
Vijaypura to Jaipur ............. ----km
Hyderabad to Surat ............. ----km
Ujjain to Shimla ............. ----km
Patna to Raipur ............. ----km
Delhi to Kolkata ............. ----km

Answer :

Cities Distance on map Actual Distance
Mumbai to Bengaluru 0.98 cm 980 km
Vijaypura to Jaipur 2 cm 2000 km
Hyderabad to Surat 0.9 cm 900 km
Ujjain to Shimla 1.14 cm 1140 km
Patna to Raipur 0.75 cm 750 km
Delhi to Kolkata 1 cm 1000 km

Question 3.

(a) The distance between two points A and B on the Ground is 500m. Show this distance on paper by a line of 2cm. Express the map scale by any one method and mention it.

Answer :

(b) Convert verbal scale of 1cm = 53km to a numerical scale

Answer :

  • 1 kilometre is equal to 100000 centimetres. Therefore, 53 kilometres is equal to 5300000 centimetres.
  • Therefore, the verbal scale of 1 cm= 53 km can be converted to a numerical scale as — 1 : 5300000.

(c) Convert the numerical scale of 1:10,000 000 to a verbal scale in the metric system.

Answer :

  • 100000 centimetres is equal to 1 kilometre. Thus, 10000000 centimetres is equal to 100 kilometres.
  • Therefore, numerical scale of 1 : 10000000 to a verbal scale in the metric system can be converted as 1 cm = 100 km.

Question 4. Help them, using road and railway maps of the state of Maharashtra. Use the scale given in the maps.

Answer :

It is activity based question, student should do it by self
