Answer:
With the help of conventional symbols, we can read a map made in any country without knowing the languages of that country. These symbols make the map reading easy and quick.
E. Answer the following questions.
Question 1.
Why is a globe considered a perfect representation of the Earth? Give any three reasons.
Answer:
- A globe represents the three-dimensional view of the earth. It shows the shape of the oceans and the continents correctly.
- It gives us a better idea of parallels i. e., latitudes and meridians i.e., longitudes.
- It helps us to understand how day and night occur and how seasons are caused.
Question 2.
What is a scale? Why is it an important component of a map?
Answer:
A scale refers to the ratio between the distance on a map and the actual distance on the ground. A map shows a large area on a small sheet of paper. Each map is drawn according to a scale. The map scale is the ratio of distance between two points on a map with the actual distance between the same points on the ground. So, the scale written on the map can be converted by the given ratio and the actual distance between the two points can be found out.
Question 3.
Distinguish between a physical and a political map.
Answer:
Physical map. These maps represent relief features like mountains, plains and plateaus, rivers, lakes, etc.
Political map. These maps show cities, towns, states and countries of the world.
Question 4.
If you are lost in a jungle, how can a topographic map help you to come out of the jungle?
Answer:
Topographical maps show great details of both natural and man-made features of a small area, with the help of conventional symbols. So, geographers, geologists and surveyors use such map all over the world. Hence, these maps help us to come out of the jungle.
Question 5.
Describe the history of map-making.
Answer:
The earliest map was made in 2300 BC in Mesopotamia (Iraq). It was made on a clay tablet. But the maps of that period were not very clear. They only showed the boundry of the land. Different techniques of map-making were adopted in different parts of the world. Eskimos made maps by sewing animal skins of different colours.
The Egyptians engraved the boundaries and features on metal plates. The ancient maps were based on memory and information. They were not drawn to a scale. Ptolemy, an Egyptian, was the first cartographer, who made the map of the world according to scale and direction. He was the first person to represent the earth as a sphere. He was known as the ‘Father of map making’.
With the development of computer technology, the techniue of map-making has undergone changes. A computer helps to draw very accurate, sharp and neat maps. The new maps possess high degree of accuracy.
Value-Based Question
Christopher Columbus was an Italian bom navigator who sailed for Spain. He thought earth is round and on the other side of Europe, India is located. He was seeking a western sea route from Europe to Asia. On the morning of October 12, 1492, he stepped ashore on an island in America with the impression that he reached India. Although, Christopher was mistaken in his goal but he helped the world to know about America. He had shown magnificent seamanship and powerful leadership. He had shown courage and dedication in his long voyage over the unknown sea of darkness. ‘Christopher Columbus is known as a great voyager.’ How does his life inspire you?
Answer:
Christopher Columbus was the son of a weaver. But he had shown courage and dedication in his long voyage over the darkness of sea. He did not set out to discover a new world. He set out with a desire to expand the knowledge of the sea and sea routes. While never knowing exactly what he had discovered, his discovery made other explorers willing to embark on voyages that would come to make up the Era of Discovery. He was the first and his voyages encouraged others. His life inspires us that we can also get some unexpected good result if we do our work dedicatedly.

C. Short Answer Type Questions
Question 1.
What is a compass? Wute in brief about it.
Answer:
A compass is an instrument used to find directions. It has a magnetic needle which rotates freely on a pivot. By placing it on a plain surface, the needle comes to rest. It Lhen points the north and south direction. The darker or coloured sides of the needle at rest, always points towards north.

D. Long Answer Type Questions
Question 1.
What are the main components of a map? Describe them.
Answer:
The main components of a map are-scale, direction, symbols and colour scheme.
1. Scale. Maps are drawn according to a scale. The map scale is the ratio of distance between two points on a map with the actual distance between the same points on the ground. For example, if the distance of 5 km on ground is represented as 1 cm on the map, the scale written on the map shall be 1 cm = 5 km. The same can be represented on a scale which is called linear scale.
2. Direction. It indicates the location and position of the places in relation to each other. North, south, east and west are the cardinal points of the compass. North-West, SouthWest, Sout-East and North-East are intermediate directions.
3. Symbols. Symbols are used to show forests, rivers, hills, railway lines and roads on a map. These symbols are universally accepted and help in map-reading. We call these symbols conventional symbols.
4. Colour scheme. There is a common colour scheme used to show different relief features on a map. For example, blue colour is used for showing water-bodies, green colour is used for showing low lands and plains, etc.
Question 2.
