Maps and Map Reading
1. Fill in the blanks with appropriate words.
(a) A representative drawing of the earth or a part of it on a flat surface is called a map.
(b) A map that shows mountains, rivers, deserts, etc. is called a physical map.
(c) A map that shows political boundaries, cities, towns, etc. is called a political map.
(d) The ratio between distance on the ground and distance on the map is called the scale.
(e) An accurate drawing of a building, park, etc. is called a plan.
2. Choose the correct answer.
(a) Maps showing the distribution of rice, sugar cane and wheat, etc. in India are
(i) political maps.
(ii) physical maps.
(ii) thematic maps. (✔)
(iv) sketches.
(b) Scale on a map is an essential requirement
(i) to show symbols.
(ii) to measure distance. (✔)
(iii) to find intermediate directions.
(iv) to show cardinal directions.
(c) A political map of India shows
(i) longitude and time.
(ii) states and capitals. (✔)
(iii) mountains and rivers.
(iv) major train routes.
(d) The layout of a school building can be best shown by a Vi plan. (iv) aerial photograph.
(i) plan (✔)
(ii) map.
(iii) sketch.
(iv) aerial photograph.
(e) The location of shops, cinema halls, hospitals, etc. in our neighbourhood can be shown using a/an
(i) sketch. (✔)
(ii) plan.
(iii) aerial photograph.
(iv) physical map.
3. Match the column:
A-B
States - physical maps
mountains -thematic
north-east - intermediate point
rainfall - scale
ratio-political maps
Solution--
A-B
States - political maps
mountains - physical maps
north-east - intermediate point
rainfall - thematic
ratio-scale
4. Write true or false. Correct the false sentences in your notebook.
(a) A scale on a map shows correct direction. False
Scale is the ratio of the distance between two places in a map and the distance between the same two places on the ground.
(b) The globe is the actual representation of the earth. True
(c) 1 cm = 500 km is a small scale map. True
(d) 1 cm = 2 km is a small scale map. False
These maps show landforms like mountains, plains, rivers, coastline features, etc.
(e) A physical map shows towns and cities. False
Physical maps show landforms like mountains, plains, rivers, coastline features, etc.
5. Answer the following questions in one or two sentences.
(a) Why do maps have an advantage over globes? Give two reasons.
Ans- Maps have following advantages over globe:
1- They can show accurate details of even very small areas.
2- Maps can be easily carried from one place to another.
3- Maps can be used to understand the relationship between different aspects. For example, we can place the rainfall map of an area on the vegetation map of the same area to understand the relationship between the two.
(b) What is the importance of a scale on a map?
Ans- A scale is defined as a relationship or ratio of the distance between two places on a map and the actual distance between the same two places on the ground.
The scale helps us to find out the distance between two places from a map.
(c) What do you understand by cardinal points?
Ans- There are four major directions on a compass which is used to find directions on the ground- North(N), South(S), East(E), and West(W). These directions are called the cardinal directions.
(d) What is the North Line?
Ans- Most maps have an arrow or a line with N (for North) written on the top. This line is called the north line.
With the help of it all the directions can be understood.
(e) What is the need to have conventional signs and symbols in a map?
Ans- There is an international understanding for using symbols to show different features in maps. These symbols are called conventional signs or symbols. They are necessary, so that people of different countries who speak different languages can easily understand maps.
6. Answer the following questions in four or five sentences.
(a) Explain the different types of map scale with examples.
Ans- A scale is defined as the relation for ratio of the distance between two places on a map and the actual distance between the same two places on the ground. There are two types of map scales:
1- Small Scales- If 1 cm on paper covers 200 km on the ground, then the detailed features cannot be shown in the map. Such maps are called small scale maps.
2- Large Scales- If 1 cm represents only 1 kilometre, then the map can show many more features. Such maps are called large scale maps.
(b) Explain the difference between cardinal and intermediate directions.
(c) Why are conventional signs important?
Ans- Conventional signs are important because they are used on most maps all over the world. People of different countries who speak different languages can easily understand these symbols. Geographers have internationally accepted these signs and symbols.
(d) What is a sketch?

A sketch is a rough drawing that one can use to show the location of a place. Sketches have no scale to give accurate measurement of distances. However, such drawings are used as a base for preparing a proper final plan or a map at a later stage.
For example, a shop on a street across from your home or a temple on the far side of your town or a picnic spot can be shown using a sketch.
(e) What is a plan? How is it different from a sketch?
(Image courtesy: Wikipedia)
Plans are accurate drawings of a small area on a large scale. These are made by architects and town planners. Plans are made to scale and show correct directions.
Such drawings generally show the layout of buildings, parks, hospitals, roads and parking, public gardens, playgrounds, classrooms, etc.
