5V. Answer the following in a sentence or two.1 questions
Q.G51. Define “Map scale”.v
Solution

Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground.
The map scale is stated in words i.e., 1 cm to 1 km.
2. What is a physical map?
Map which shows the physical feature of an area is called a physical map.
3. Write a short note on map projection.
A map projection is a way of representing the spherical earth on a flat surface of a map. The curved surface of the earth cannot be shown accurately on a map. So, cartographers use map projections while mapping the earth surface which would help them to reduce distortions.
Samacheer Kalvi 9th Social Science Guide Geography Chapter 7 Mapping Skills
4. Name the Intermediate directions.
The intermediate directions are northeast, north west, south east, and south west.
5. What are the uses of a cadastral map?
Cadastral maps are useful for local administration such as the city survey, taxation, management of estates and to define property in legal documents.

Answer:

Map scale refers to the relationship (or ratio) between distance on a map and the corresponding distance on the ground.
The map scale is stated in words i.e., 1 cm to 1 km.

6VII. Answer in a paragraph.2 questions
Q.G61. Explain the different types of scales in detail.v
Solution

Scales on maps can be represented in three different ways. They are:
Statement or Verbal scale
Representative Fraction (RF) or Ratio Scale
Graphical or Bar Scale
1. Statement or Verbal scale:
In this method, the map scale is stated in words i.e., 1 cm to 1 km.
It means 1 cm distance on the map corresponds to 1 km distance on the ground.
Thus it is written on the map like 1 cm to 1 km.
2. Representative Fraction (RF) or Numerical Fraction or Ratio Scale:
It shows the relationship between the map distance and the corresponding ground distance in the same units of length.
R.F. is generally shown as a fraction.
3. Graphical or Bar Scale or Linear Scale:
A graphic scale looks like a small ruler drawn at the bottom of the page.
This line is divided and sub-divided into lengths each of which represents a certain distance on the ground.
This scale has an added advantage for taking copies of maps as the measurement does not change.
Samacheer Kalvi 9th Social Science Guide Geography Chapter 7 Mapping Skills
2. Describe the Cadastral map and its importance.
The Cadastral map refers to a map which shows the boundaries and ownership of land within a specified area.
They are sometimes called plans.
They show full details of boundaries and buildings.
They are useful for local administration such as city survey, taxation to define property in legal documents.
It is maintained by the government as a public record.
Importance:
It surveys documents boundaries of land ownership, diagrams, sketches plan, and maps.
They are originally used to ensure reliable facts for land valuation and taxation.
3. Write a paragraph about the conventional signs and symbols.
The conventional signs and symbols:
Conventional signs are symbols used in maps to represent different features.
The symbols are explained in the key of the map.
These symbols give a lot of information in a limited space.
With the use of these symbols, maps can be drawn easily and the concept of the map can be understood well. There is an international agreement regarding the use of certain symbols.
The symbols that fall under this category are Called Conventional Symbols. Another category is called contextual symbols which are decided by the cartographers.

Answer:

Scales on maps can be represented in three different ways. They are:
Statement or Verbal scale
Representative Fraction (RF) or Ratio Scale
Graphical or Bar Scale
