Map Scale Class 8 Geography Question b.
There are two maps with respective scales of 1cm = 100 m and 1cm = 100 km. Give well reasoned answer as to which of them would be a large scale map and which a small scale map. Recognize the types of maps.
Answer:
A. 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.
B. Reasons :

  1. 1 metre is equal to 100 centimetres and 100 metre is equal to 10000 centimetres.
  2. Thus, the value of the given verbal scale (1cm = 100 m) is 1 : 10000 in numerical terms (scale).
  3. 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.

C. Types of maps :

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

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

Write short notes on:

Question a.
Verbal scale.
Answer:
1. A scale in which distances are expressed with the use of words indicating measurement is called verbal scale.
2. For example, 1cm = 100 km.

3. In verbal scale, the word indicating measurement on the left hand side indicates the distance between any two points on a s map. On the other hand, the word indicating 1 measurement on the right hand side! indicates the ground distance between those two points.

4. When the map is reduced or enlarged by taking its photo copy, the verbal scale on the original map does not change.

Question b.
Numerical scale.
Answer:

  1. Numerical scale: A scale in which distances are expressed as ratio is called numerical scale.
  2. For example, 1:10000. It is also known as representative fraction.
  3. In numerical scale, the same measuring unit is used for the figures on the left hand side and right hand side. However, no words are used to indicate this measuring unit.
  4. In numerical scale, number 1 on the left hand side indicates the distance between any two points on a map. On the other hand, the number 10000 on the right hand side indicates the ground distance between those two points.
  5. When the map is reduced or enlarged by taking its photo copy, the numerical scale on the original map does not change.
